From North Korean nuclear tests to home-grown Mentos-n-Coke cocktails, if there's one thing our world has plenty of these days, it's explosions. Despite the frequency of modern explosions, however, there are a few historical booms which blow away the competition -- pun intended -- and are remembered today not only for their awesome destructive force, but for being audible many hundreds, if not thousands, of miles away.
The Tunguska Event
The cause of this famous 1908 explosion in Siberia is still contested by some -- everything from alien spacecraft to long-distance energy transmission experiments by Nikola Tesla gone wrong have been posited as its cause -- though most experts believe the culprit was a meteor, which exploded while it was still about six miles above a remote portion of Siberian forest. The blast released 15 megatons of energy—about a thousand times that of the atomic bomb dropped on Hiroshima—and flattened 770 square miles (2,000 square kilometers) of forest. The shock wave broke windows and knocked people off their feet hundreds of miles away, and according to the 1966 Guinness Book, due to the rotation of the Earth, if the meteor had fallen just four and a half hours later it would've wiped the city of St. Petersburg from the map. And in semi-breaking news, scientists think they may have just found the meteorite's impact crater -- some 99 years later.
Certainly the biggest bang in recent history, the 1893 volcanic explosion on the Indonesian island of Krakatoa rocked the Southern hemisphere, sending 120-foot tidal waves crashing into nearby Java and Sumatra, smoke and debris into the atmosphere in such prodigious quantities that it caused global cooling of about four degrees over the next year, and could be heard from as far away as Perth, Australia (1,930 miles) and the island of Rodrigues near Mauritius (a stunning 3,000 miles distant). And as long as we're comparing explosions to Hiroshima, Krakatoa's force was about 1,000,000 times that of the famed nuke. What's more, all that atmospheric debris made for some dramatically blood-red sunsets 'round the world, which apparently inspired the apocalyptic sky in Munch's The Scream.
It seems no one can throw an eruption like Indonesia, also the site of the devastating 1815 eruption of Mount Tambora. The deadliest eruption ever recorded (it probably claimed some 92,000 victims), it ejected so much light-blocking debris into the atmosphere that 1816 was known as "The Year Without a Summer." Indeed, the crop failures and livestock deaths that resulted in much of the Northern hemisphere caused the worst famine of the 19th century -- all thanks to one big explosion. Though more destructive, it doesn't seem to have been as loud as Krakatoa (it was heard a mere 1,200 miles away on Sumatra), though that's still pretty darn loud. In 2004, archaeologists discovered extensive, Pompeii-like remains beneath deep pockets of eruption deposit, including victims, homes and items undisturbed in the positions they had held since the morning they were buried.
An urban legend about a videotape that kills its viewers seven days after they see it turns out to be true. To her increasing horror, reporter Rachel Keller (then-newcomer Naomi Watts) discovers this after her niece is one of four teenage victims, and is in a race against the clock to uncover the mystery behind the girl in the video before her and her son’s time is up.
Released 15 years ago, on October 18, 2002, The Ring began a trend of both remaking Japanese horror films in a big way, and giving you nightmares about creepy creatures crawling out of your television. Here are some facts about the film that you can feel free to pass along to anybody, guilt-free.
1. DREAMWORKS BOUGHT THE AMERICAN RIGHTS TO RINGU FOR $1 MILLION.
There were conflicting stories over how executive producer Roy Lee came to see the 1998 Japanese horror film Ringu, Hideo Nakata's adaptation of the 1991 novel Ring by Kôji Suzuki. Lee said two different friends gave him a copy of Ringu in January 2001, which he loved and immediately gave to DreamWorks executive Mark Sourian, who agreed to purchase the rights. But Lee’s close friend Mike Macari worked at Fine Line Features, which had an American remake of Ringu in development before January 2001. Macari said he showed Lee Ringu much earlier. Macari and Lee were both listed as executive producers for The Ring.
2. THE DIRECTOR FIRST SAW RINGU ON A POOR QUALITY VHS TAPE, WHICH ADDED TO ITS CREEPINESS.
Gore Verbinski had previously directed MouseHunt. He saidthe first time he "watched the original Ringu was on a VHS tape that was probably seven generations down. It was really poor quality, but actually that added to the mystique, especially when I realized that this was a movie about a videotape." Naomi Watts struggled to find a VHS copy of Ringu while shooting in the south of Wales. When she finally got a hold of one she watched it on a very small TV alone in her hotel room. "I remember being pretty freaked out," Watts said. "I just saw it the once, and that was enough to get me excited about doing it."
3. THE RING AND RINGU ARE ABOUT 50 PERCENT DIFFERENT.
Verbinski estimated that, for the American version, they "changed up to 50 percent of it. The basic premise is intact, the story is intact, the ghost story, the story of Samara, the child." Storylines involving the characters having ESP, a volcano, “dream logic,” and references to “brine and goblins” were taken out.
4. IT RAINED ALMOST EVERY DAY WHEN THEY FILMED IN THE STATE OF WASHINGTON.
5. THE PRODUCTION DESIGNER WAS INFLUENCED BY ANDREW WYETH.
Artist Andrew Wyeth tended to use muted, somber earth tones in his work. "In Wyeth's work, the trees are always dormant, and the colors are muted earth tones," explained production designer Tom Duffield. "It's greys, it's browns, it's somber colors; it's ripped fabrics in the windows. His work has a haunting flavor that I felt would add to the mystique of this movie, so I latched on to it."
6. THERE WERE RINGS EVERYWHERE.
The carpeting and wallpaper patterns, the circular kitchen knobs, the doctor’s sweater design, Rachel’s apartment number, and more were purposely designed with the film's title in mind.
7. WATTS AND MARTIN HENDERSON HAD A FRIENDLY INTERNATIONAL RIVALRY.
The New Zealand-born Henderson played Noah, Rachel’s ex-husband. Since Watts is from Australia, Henderson said that, "Between takes, we'd joke around with each other's accents and play into the whole New Zealand-Australia rivalry."
8. THE TWO WEREN’T SURE IF THE MOVIE WAS GOING TO BE SCARY ENOUGH.
After shooting some of the scenes, and not having the benefit of seeing what they'd look like once any special effects were added, Henderson and Watts worried that the final result would not be scary enough. "There were moments when Naomi and I would look at each other and say, 'This is embarrassing, people are going to laugh,'" Henderson told the BBC." You just hope that somebody makes it scary or you're going to look like an idiot!"
9. CHRIS COOPER WAS CUT FROM THE MOVIE.
Cooper played a child murderer in two scenes which were initially meant to bookend the film. He unconvincingly claimed to Rachel that he found God in the beginning, and in the end she gave him the cursed tape. Audiences at test screenings were distracted that an actor they recognized disappears for most of the film, so he was cut out entirely.
10. THEY TRIED TO GET RID OF ALL OF THE SHADOWS.
Verbinski and cinematographer Bojan Bazelli used the lack of sunlight in Washington to remove the characters’ shadows. The two wanted to keep the characters feeling as if “they’re floating a little bit, in space.”
11. THE TREE WAS NICKNAMED "LUCILLE."
The red Japanese maple tree in the cursed video was named after the famous redheaded actress Lucille Ball. The tree was fake, built out of steel tubing and plaster. The Washington wind blew it over three different times. The night they put up the tree in Los Angeles, the wind blew at 60 miles per hour and knocked Lucille over yet again. "It was very strange," said Duffield.
Moesko Island Lighthouse is Yaquina Head Lighthouse, at the mouth of the Yaquina River, a mile west of Agate Beach, Oregon. The website Rachel checks, MoeskoIslandLighthouse.com, used to actually exist as a one-page website, which gave general information on the fictional place. You can read it here.
13. A WEBSITE WAS CREATED BY DREAMWORKS TO PROMOTE THE MOVIE AND ADD TO ITS MYTHOLOGY.
Before and during the theatrical release, if you logged into AnOpenLetter.com, you could read a message in white lettering against a black background warning about what happens if you watch the cursed video (you can read it here). By November 24, 2002, it was a standard official website made for the movie, set up by DreamWorks.
14. VERBINSKI DIDN’T HAVE FUN DIRECTING THE MOVIE.
“It’s no fun making a horror film," admitted Verbinski. "You get into some darker areas of the brain and after a while everything becomes a bit depressing.”
This isn’t just any image of Africa. It represents the first of its kind: a high-resolution map of the different types of land cover that are found on the continent, released by The European Space Agency, as Travel + Leisure reports.
Land cover maps depict the different physical materials that cover the Earth, whether that material is vegetation, wetlands, concrete, or sand. They can be used to track the growth of cities, assess flooding, keep tabs on environmental issues like deforestation or desertification, and more.
The newly released land cover map of Africa shows the continent at an extremely detailed resolution. Each pixel represents just 65.6 feet (20 meters) on the ground. It’s designed to help researchers model the extent of climate change across Africa, study biodiversity and natural resources, and see how land use is changing, among other applications.
Developed as part of the Climate Change Initiative (CCI) Land Cover project, the space agency gathered a full year’s worth of data from its Sentinel-2A satellite to create the map. In total, the image is made from 90 terabytes of data—180,000 images—taken between December 2015 and December 2016.
The map is so large and detailed that the space agency created its own online viewer for it. You can dive further into the image here.
And keep watch: A better map might be close at hand. In March, the ESA launched the Sentinal-2B satellite, which it says will make a global map at a 32.8 feet-per-pixel (10 meters) resolution possible.
