Around the world, over 600 million people live near one of 1500 active terrestrial volcanoes. Who's keeping them safe from potential future eruptions? The women and men who study these gas-and-ash-and-lava belching windows into the center of the earth: volcanologists.

You might not be sure what volcanologists do or why they matter—especially if you live thousands of miles away from one of these fiery mountains. So, Mental Floss went searching for answers from four volcanologists working in various capacities around the country, who shared their experiences in the field, under the ocean, and gazing far out into space.

1. THEY STUDY EVERYTHING FROM MAGMA COMPOSITION TO VOLCANIC GASSES AND BEYOND.

"When I tell people what I do, 95 percent of the time they ask, 'What is that?'" says Arianna Soldati of the University of Missouri, who researches lava flows.

Volcanology is the study of how volcanoes form, what they're made of, and what they eject, among other areas of research. Many volcanologists have degrees in geology; some, like Soldati, are physical geologists, collecting samples on site and then analyzing them to figure out their composition. Others are geophysicists who study tectonic plates and their role in volcanic eruptions and earthquakes. Geochemists and petrologists study volcanic gasses and minerals, and geodesists look at deformations on and around volcanoes to figure out if magma is pooling up underneath them. All these disparate disciplines work together, Soldati says, to "understand how the planet works, so we can understand how eruptions work."

2. THEY WORK WITH OTHER VOLCANOLOGISTS AROUND THE GLOBE IN THE NAME OF SAFETY.

Jacob Lowenstern is Chief of the Volcano Disaster Assistance Program at the United States Geological Survey (USGS), a government agency that monitors our country's 169 active land volcanoes, largely via observatories in Hawaii, Alaska, Washington, and Oregon. But it also offers assistance and training to volcanologists in other countries because, as Lowenstern points out, an active volcano system respects no human borders. The program helps keep people and animals safe from the destruction wrought by lava flows, mudslides, and gas: When eruptions happen, localities issue alerts based on data from USGS.

Underwater volcanoes can create shipping hazards, like floating chunks of pumice, but a land-based volcano can create serious chaos worldwide. When Iceland's Eyjafjallajökull erupted in 2010, its miles-high ash cloud grounded aircraft to and from Europe and Britain for about a week. "We didn't even know what concentration of ash it was safe to fly through, because no one had studied it before," Soldati says. (They do know now, although the answer depends on how long the aircraft is aloft [PDF]). Back when Tambora erupted in Indonesia in 1815, it kicked off the Year Without a Summer, as ash circled the globe and blocked out the Sun, resulting in crop failures, famine, and a total of 100,000 human deaths. "At some point, something truly global [like that] is going to happen again," Lowenstern says. Volcanologists aim to be prepared.

3. SOME OF THEM WORK UNDERWATER ...

An estimated 80 percent of eruptions happen beneath the oceans' waves. It hasn't been easy for volcanologists to research them—for starters, there was no comprehensive map of the ocean floor until just a few years ago. And not being able to see a volcano that's 3000 feet underwater makes observation … challenging. Historically, scientists mostly monitored underwater volcano activity using fickle, battery-operated equipment installed on the seafloor, which could only store (rather than transmit) data. The first complete footage of an underwater eruption wasn't captured till 2009.

William Wilcock says technology has finally caught up to the thirst for information. He studies the Pacific Ocean's Axial Seamount—the most active volcano in the Northeast Pacific—via the Cabled Array ocean observatory, 550 miles of fiber-optic cable equipped with sensors that allow scientists to to monitor the Juan de Fuca ridge off of Oregon's coast. Using the array, they can monitor the chemicals and temperature in the water column, measure the volcano's magma chamber, and keep tabs on earthquakes, which could signify an eruption.

The array sends underwater volcanologists data in real time—fast enough that they can sometimes deploy autonomous vehicles for a closer look at eruptions as they happen. In April 2015, the project's team was able to witness an entire eruption of Axial Seamount from start to finish, leading to “the most detailed observations ever made” of an undersea volcano, as Wilcock told The Washington Post. The data they gleaned helped them understand how the seamount's caldera falls during eruptions and then reinflates with gases and magma before reaching a particular threshold, at which it erupts. Understanding how that inflation works is important for land volcanoes too, which is part of why data from the array is posted on the internet for scientists around the world to use.

4. ... AND SOME STUDY VOLCANOES IN SPACE.

The only scientist NASA sent to the moon was geologist Harrison “Jack” Schmitt, who flew on Apollo 17. (All of the other astronauts were military men-turned-NASA test pilots.) Schmitt—who was actually allergic to regolith, a.k.a. moon dust—helped prove that the moon was once volcanically active. This fact makes NASA's Alex Sehlke incredibly proud—and envious. He's a volcanologist who conducts research in Idaho's Craters of the Moon National Monument in preparation for the agency's planned return there in a few years. Craters of the Moon is geologically similar to our actual moon, in part because it was formed by lava erupting from the middle of the continent, not a juncture where two plates meet; moon volcanos were likely formed in a similar fashion, since the moon is covered, basically, by a single giant plate.

Volcanologists like Sehlke usually play supporting roles in space exploration. They test equipment and speculate about how, say, Craters of the Moon's lava tubes are like those under the surface of the actual moon and might make for a good base of operations. "Imagine looking at the surface of the moon [from Earth] when you're planning a mission and saying, ‘Hmm, looks alright,'" Sehlke says. "But there are questions we need to answer before we go—maybe the terrain is treacherous."

They may also offer guidance from mission control to astronauts (often about areas that look like they might be interesting to explore), and analyze data from probes—like the first images of an ice volcano erupting on Saturn's moon Enceladus, captured by the Cassini spacecraft in 2005.

5. SOME OF THEM ARE LOOKING FOR THE BEGINNINGS OF LIFE.

Hydrothermal vents—openings in the seafloor where water enters, becomes heated, then spurts back out—support a lot of weird microbes that Wilcock says may be similar to the first organisms that ever existed on our planet. Studying them and the conditions that created them may help us understand how to look for life on other planets and moons—one of NASA's primary objectives. But Sehlke and others are also looking for life by scanning data from probes exploring our solar system: "Wherever volcanoes sit, on Enceladus or elsewhere, there is heat or fluids that maybe provide the necessary environment for microorganisms like the ones we know on Earth," Sehlke says. Volcanoes like these "give us the highest chance of finding life" out in space.

6. THEY ALSO WANT TO UNDERSTAND HOW TO SUSTAIN THE LIFE WE ALREADY HAVE.

While volcanoes created Earth's original atmosphere by emitting the carbon dioxide and nitrogen necessary for life, other volcanic gasses, like sulfur dioxide, increase the ability of our current atmosphere to retain heat [PDF]. "Learning how these things balance out is hugely important to understanding our future" on the planet, Soldati says. That's why new studies are looking at the links between volcanic activity and climate change, and how they may exacerbate each other.

Some volcanologists are particularly concerned about Iceland, where melting ice caps may be releasing pressure on magma chambers, contributing to more—and more explosive—volcanic eruptions in the future. The effect of the reduced pressure is similar to how “the cork of a champagne bottle flies into the air when it has loosened sufficiently,” geophysicist Magnus Guðmundsson told Hakai magazine. Another new study urged those making models of our climate future to include volcanic eruptions as a variable, which they find are under-sampled in such models but can have big effects on temperatures, sea levels, global radiation, and ocean circulation, among other key elements of the climate.

7. THEY GET TO USE A LOT OF COOL EQUIPMENT ...

Volcanologists use a lot of very high-tech equipment in their line of work. Seismometers measure earthquakes on volcanic slopes. Infrared cameras measure the heat of lava flows. Correlation spectrometers measure the amount of sulfur dioxide in the air, which is released when magma is rising to the surface (and so can signal when a volcano might be ready to erupt). Tiltmeters measure, literally, the tilt of the land around a volcano. If instruments like these, having been mounted on a volcano, fall apart during an eruption, "we sometimes use helicopter drops to put new equipment on the ground," Lowenstern says. More and more, though, volcanologists monitoring land volcanoes rely on equipment mounted on aerial or space-based unmanned craft, "so we don't put people in harm's way." This includes technology called InSAR (Interferometric Synthetic Aperture Radar), which, from a satellite in space, can measure a volcano stretching and contracting. That helps scientists keep tabs on just what the magma inside a volcano is doing—and whether it's about to come up.

8. ... BUT ONE OF A VOLCANOLOGIST'S MOST IMPORTANT TOOLS IS A ROCK HAMMER.

Out in the field, Soldati says, her most important tools are her notebook, for jotting observations, and her steel rock hammer, which she uses both to chip away at rock and to gather samples of molten lava. To grab a sample, she swings into the lava with the pointed end of the hammer, then drops the molten material—which is around 2000°F—into a pail of water; quickly cooling the lava in this way turns it to glass (slow cool it, and it becomes rock), which she transports back to the lab.

Once there, Soldati relies on machines like a concentric cylinder viscometer, which melts lava samples so she can measure their viscosity—which tells her how explosive a volcano's eruptions are. Less viscous lava trickles out of a volcano, while more viscous, and hence more explosive, lava can blow out the whole side of a mountain, sending burning lava, rocks, and other debris flying.

9. IT DOESN'T LOOK LIKE THE MOVIES.

Volcanologist suit

One thing field volcanologists almost never use: those clichéd silver flame-proof proximity suits. "They're heavy, and since you usually have to walk hours to get to your field site, no one wants to carry all that weight," Soldati says. Besides, "heat is almost never the hazard that matters in the situations in which we work," writes Aaron Curtis, a volcanologist working at NASA's Jet Propulsion Laboratory. (You have a greater chance of "being hit by ballistics, or getting gassed," he notes.) "The reason you see those suits so often is that they look really cool on TV."

So what do they wear? Jessica Ball, a Postdoctoral Fellow at the U.S. Geological Survey, writes that "sturdy boots, hard hats, work gloves, rip-resistant clothing with long sleeves, and sunglasses or safety goggles are pretty standard, and I will add a gas mask if I’m going to be in an area with lots of fumes. Also, sunscreen is always important, because I’m often out in the sun all day."

10. SOME OF THEIR WORK IS DANGEROUS IN UNEXPECTED WAYS.

Lava and flying debris aren’t the only hazards during fieldwork. Tina Neal, a volcanologist with the USGS, has reported that she’s had several encounters with bears while working at Ukinrek Maars in Alaska. She also says, "I think the aircraft work of volcanologists is as dangerous if not more so than the active volcanoes we visit and study." Geologist Christina Heliker has described the most fearful moments during her time on staff at the Hawaiian Volcano Observatory as being those that involved flying in a helicopter over continuously active Pu`u `O`o. Once, while trying to return to camp after mapping lava flows, “It was almost dark, and we were sandwiched between an incandescent field of `a`a [lava] and this thick layer of clouds that were glowing orange from the reflected light of the lava,” she told an interviewer. “I was plenty relieved when the pilot decided to give it up and fly out to somewhere else.”

11. THEY WANT YOU TO KNOW: VOLCANOES AREN'T ALL BAD.

Volcanologists aren't drawn to their work only because of the destructive power of their research subjects. "[Volcanoes] also have a positive impact on our life," Soldati says. She points out that volcanoes fertilize the soil—some of the most productive crops on our planet are grown in mineral-rich volcanic ash. They also create new land; the Hawaiian volcano Kilauea has added 500 acres to the Big Island since 1983. So don't say volcanoes never give back.

14 Secrets of Cruise Ship Workers

From an outsider’s perspective, working on a cruise ship might seem like a dream job. What could be more glamorous than getting paid to travel the world by sea, without having to pay for housing or food? But as with many “dream” jobs, there are a few significant downsides to consider before you fill out an application. We spoke to a few cruise ship employees about what it’s like to live and work on a floating hotel.

1. Americans are the worst cruise workers.

On most large cruise liners, the majority of staff and crew are not American. “On any given contract, you’re working with about 64 nationalities,” says Kat, who spent three years working for a major cruise line. There are a number of possible drivers behind this statistic, but one is that cruise ship employees work really long hours and almost never get a day off, which isn’t particularly appealing to Americans used to a 40-hour workweek and relaxing on weekends. “On my worst contract, I was working close to 300 hours a month,” Kat says. “Yeah, you might be in beautiful places, but you’re so tired sometimes you don’t even want to go out and explore. A lot of times they won’t even hire Americans because the rate of people quitting is so high.”

Americans are also more expensive to employ, even if they do the same work as their counterparts from developing countries. Sam, who worked on Princess Cruises for two years, says her monthly salary of $1100 was higher than that of her Filipino boss. According to Sam, the official reason the ship gave was that the dollar is worth more to people from developing countries than it is to Americans.

2. Cruise ship workers are trained for pirate attacks.

It’s rare for pirates to take on a massive cruise ship, but it can happen, and if it does, the crew is prepared. Nolan, who worked for both Princess Cruises and Oceania Cruises, says he was trained to get all guests away from windows and spray the intruders with giant water cannons.

“Our ship can totally outrun their little dinghies,” he says. “We could spray them with water and they’d be helpless.” Other ships may be equipped with Long Range Acoustic Devices that emit loud, painful noises to deter attacks. That’s how a luxury cruise liner escaped a pirate attack off the coast of Africa in 2005.

3. Want to lose weight? Work on a cruise liner.

While passengers are feasting on steak and scrumptious seafood, the staff and crew aren’t so lucky. “Imagine eating at your high-school cafeteria three meals a day, seven days a week for a year,” writes one former cruise ship worker on Reddit. Kat recalls strange offerings like goat foot stew. The unappetizing food, combined with the many hours spent running the length of the ship, often mean crew members lose a significant amount of weight during their time at sea. “I would lose about 10 to 12 pounds per contract,” Kat says.

Gavin, who worked as a waiter for a major cruise line, said the crew would occasionally get treated to whatever leftovers remained from the passenger buffet, but “it would disappear so fast.”

4. Crew members sometimes mess with passengers.

Life at sea can get a bit monotonous. “It got mundane really fast,” writes one former worker on Reddit. “It was basically the same comedy of errors each day of the week, with a different ‘cast’ of passengers each week.”

Some crew members shake things up by getting a rise out of passengers in the form of good old practical jokes. According to another former crew member, “a favorite was while in a passenger area say to another crew member, loud enough to be heard by passengers, ‘Meet you in the bowling alley tonight!’” Of course, there wasn’t actually a bowling alley on board. “Then we'd wait for the comment cards to come in: ‘Why do crew get a bowling alley when we don't?’”

5. … and chance are the workers might be drunk.

When they’re not working, employees are probably drinking and partying. “We partied our asses off,” Gavin says. “We joked about how it makes a frat house look like a monastery.” The staff get their own designated watering holes on board, referred to as the crew bars, where the drinks are dirt cheap. “At the passenger bars they were charging like $15 for a drink and we’d go down into the crew bar and you could get a beer or mixed drinks for $1.25,” Sam says.

And what happens when you give copious amounts of cheap alcohol to people who are cooped up together for months at a time? “It seems like a cliche, but everyone was hooking up with each other,” Sam says. “In a lot of the crew areas there were these huge posters about STD prevention.”

The crew is regularly threatened with the possibility of random breathalyzer tests (and drug testing), but even this isn’t always enforced. “There was a strict limit on our ship of no more than .04 blood alcohol content at any time,” Gavin says, “but as long as you didn’t make a fool of yourself, you wouldn’t get randomly breathalyzed, so people would break that rule all the time.”

6. For the crew, hooking up with guests on the cruise is strictly forbidden.

So you spotted a cute crew member on your ship and are thinking of chatting them up? Good luck with that. Having sexual relations with a guest is one of the fastest ways for a crew member to get fired. This is mainly to protect the cruise line from reputation-damaging accusations of abuse. Ship security keeps a close eye on crew members day and night. That doesn’t mean hookups never happen, but if a crew member is caught in the act with a guest, they’re kicked off the ship at the next port.

7. Crew passengers are almost always being watched.

“It is safe to assume if you are outside of your cabin you are probably on camera,” Gavin says. “In the event of any kind of emergency, they could pull security footage at any time.”

8. Passengers have a lot of power over how much the crew gets paid.

At the end of a journey, you might be asked to rate your experience and share any praise or complaints on a comment card. These reviews are taken very seriously and often translate directly into salaries and bonuses for workers. “For most people, their salaries are quite low and they rely on those bonuses,” Kat says. So if you leave a bad review and mention someone by name, you can be sure they’ll feel the impact on their paycheck.

“The very best thing you can do for a crew member is to write a glowing review, mentioning them specifically on your comment card,” says a former cruise worker on Reddit. “Their superior’s superiors take note of that.”

9. Some cruise workers have double lives.

“You get a lot of married people that have their own separate lives on the cruise ship,” Kat says. “I’ve worked with couples that have wives at home and a whole different relationship while they’re on the cruise ship. It’s kind of like a don’t-ask-don’t-tell policy.”

Gavin says one of his fellow employees lived as an out-of-the-closet gay man while on board, but was still closeted on land.

10. They have no idea what’s going on in the world.

“You stop following news and sports and pop culture,” Gavin says. “You’re really kind of isolated out there.” It can be difficult (and expensive) to find an internet connection while at sea, so many ship workers completely lose track of current events while on contract.

11. They speak in code.

Crew members have shorthand codes for everything from fires to medical emergencies, which they can announce over the loudspeaker without alarming passengers.

Code Adam: a child is missing
Code Alpha: there’s a medical emergency
Code Oscar: man overboard
Code Bravo: fire on the ship

12. The cruise ship has many mafias.

But not the kind that will make you an offer you can’t refuse. According to Sam, the crew members on her ship were split into “mafias” based on their country of origin, and each mafia dealt in specific goods. For example, the Indian mafia was in charge of getting good food for the crew parties, she says. Because Sam worked in the youth center, she was tasked with providing art supplies for crew costume parties. “That’s just one of the economies of the ship,” Sam says. “Everyone is always trying to figure out what they can get from another person.”

One former cruise ship worker says the Filipino mafia was known for getting good booze at all hours. “If you wanted anything after hours, they would get it for you! The crew bar would close around 1 or 2. If you wanted to keep drinking, but were out of booze, you would just go to the Filipino mafia and get what you needed. You paid a huge markup obviously, but it was still pretty cool!”

13. There’s a morgue on board.

Roughly 200 people die on cruise ships every year, and cruise lines need some place to store the bodies safely until they get back to shore. As a result, many ships have small morgues on board that can hold five or six bodies. “We definitely had a morgue on board,” one former ship employee told me. “Because the line was for older demographics, we had people die on the ship pretty regularly.”

14. They will leave you behind.

If you leave the ship for an on-land excursion, make sure you get back before departure time. Cruise lines pay massive fines if they overstay their port time, so chances are high the ship will leave without you if you’re running behind. “You’re on your own,” Kat says. “They won’t wait.”

14 Things You Might Not Know About Sephora

iStock/RiverNorthPhotography
iStock/RiverNorthPhotography

It’s the store that’s all about that face … and nails, and skin. Makeup mecca Sephora was first born as a perfumery in 1969. French business owner Dominique Mandonnaud wanted to remove fragrances from behind the counter and allow customers to touch, smell, and spritz on the scents. Three-plus decades later, the cosmetics juggernaut—which is currently in the news for shutting down its stores for an hour today (June 5) to host diversity and inclusivity workshops for all of its 16,000 employees—employs the same client-first philosophy. (Did you know you could get a free 15-minute makeup service at any location?) Try on these other facts.

1. BEAUTY IS (SORT OF) IN THE NAME.

The official line is that Sephora originates from the Greek word sephos (which the company claims means "beauty") and the name Zipporah—she was Moses’ exceptionally pretty wife in the Book of Exodus. Not everyone buys this explanation, however, noting that "sephos" is nothing like the ancient Greek word for "beauty" or "beautiful."

2. IT'S A TOURIST DESTINATION.

Approximately 6 million cosmetics-seekers stroll through the company’s Parisian flagship store on the Champs-Élysées every year. That’s almost as many annual visitors as the Eiffel Tower receives.

3. CHANGED YOUR MIND ABOUT A PRODUCT? THAT'S COOL!

Stores will take back makeup—even opened products!—within 60 days of purchase. Employees admit it’s often heartbreaking for them to have to trash barely-used makeup.

4. SHOPPERS CAN SCORE TONS OF PERKS …

Along with complimentary mini makeovers, stores offer a 45-minute session when customers spend $50, and a 90-minute consultation (it includes a makeover and personal shopping session) when they shell out $125. The company’s (free) Beauty Insider program also has its benefits. Signing up means you can attend any beauty class gratis and each dollar you spend nets you a point that you can use towards fun gifts. (In some cases, they’ll even let you go into a negative points balance to score the product.)

The company also tracks your purchases to give you recommendations for other products. (Bridget Dolan, VP of Interactive Media, told Forbes that 80 percent of their transactions “run through our loyalty program.”)  Spending $350 a year catapults you to VIB (Very Important Beauty Insider) status and gains you access to private shopping events and first dibs on new products. Shell out $1,000 annually and you get Rouge Status—that means free two-day shipping on all orders, unlimited in-store makeovers, and invites to chic store events. At one, VIBs got the chance to meet Jennifer Aniston!

5. … AND MORE SAMPLES THAN THEY KNOW WHAT TO DO WITH.

Sephora employees are told that customers shouldn’t leave without new products to try. That means you can get a trial size of just about every product they carry. (Most makeup products can be tested in-store and they’ll pour any liquid product, such as a night cream or fragrance, into a sample-size vial.) The general rule, say employees, is that customers are entitled to three samples each trip. Shopping online? Each purchase comes with a choice of three freebies. And while the store rarely has sales, you can score big at the site’s Beauty Deals section.

6. GETTING A SPECIFIC PRODUCT RECOMMENDATION CAN BE TRICKY.

Employees aren’t allowed to refer shoppers to particular brands. So instead of asking for their favorite lip shade, it’s smarter to ask which lip products perform the best. (Translation: What are other shoppers buying and not returning?)

7. NEED THE PERFECT FOUNDATION? THEY HAVE AN APP FOR THAT.

Okay, well, it’s a device. The handheld Color IQ scans the surface of your skin and then finds the scientifically precise foundation—there are 1,500 options—for your visage. To create the library, the Pantone Color Institute researched and mapped out 110 different skin tones.  

8. THEY HAVE THEIR OWN LANGUAGE.

Each store is divided into three distinct “worlds”: fragrance, skincare and color. In a 2008 interview with Jezebel, one employee spilled on the lingo. The sales floor is known as the “stage” (which makes everything else “backstage”), employees are called “cast members,” and managers are dubbed “directors.” As for the required all-black outfits, they’re not uniforms, they’re “costumes.”

9. EMPLOYEES REALLY ARE BEAUTY EXPERTS …

Some cast members undergo a month of intensive, all-day training at the company’s beauty school, Science of Sephora. There, according to the company’s website, they learn about “skin physiology, the history of makeup, application techniques, the science of creating fragrances, and most importantly, how to interact with Sephora’s diverse clientele.”

10. … AND THEIR MEDICINE CABINETS ARE STOCKED.

Employees have said working at Sephora means constantly receiving new products from companies to try out. A particularly good sales day can also net a salesperson a “gratis ticket” from their manager. Plus, there’s the 20 percent employee discount that jumps up to 30 percent during the holiday season.

11. LOOKING GOOD IS A REQUIREMENT.

Part of the employee handbook: thou shall embrace eyeliner. Cast members are told to wear a certain amount of makeup while working.

12. THEY'RE WARY OF RESALE.

One cast member says they limit people from buying more than six identical items (unless they offer a good reason, such as bridal party gifts). Explains the employee, “This is to discourage people reselling our products at their own establishments.”

13. UNPOPULAR PRODUCTS USUALLY GET THE BOOT.

Stores keep lists of the products that get returned most often, and the products that don’t work are phased out over time. While it's hard to nail down an official list of frequently-returned goods, individual employees will occasionally open up about the company's most loathed and/or most misunderstood makeup.

14. SEPHORA'S APPEAL IS WIDE.

In 2014, the L.A. Review of Books dug through the contents of a Power Mac G4 once owned by Susan Sontag and discovered the famed author was on Sephora’s Beauty Insider mailing list.
