You tube earth quake hit japan9/28/2023 ![]() “We took a boat all the way from the middle of the island up to Banda Aceh, the hardest hit area, and for hundreds of kilometers it was as if somebody had taken an eraser and erased everything underneath the 20-meter line,” says Titov. Titov will never forget the scene of widespread devastation he witnessed on Sumatra even months after the tsunami waters had subsided. “This was the most extreme tsunami event since 1960,” says Borrero, referring to the 8.6-magnitude Chilean earthquake and tsunami that punished the Pacific, including the leveling of Hilo, Hawaii, 15 hours after the quake. Borrero remembers coming upon a colossal freighter loaded with bags of cement that had been flipped on its back with its propeller in the air. It was during these expeditions that scientists confirmed maximum wave heights of more than 131 feet on the northwestern tip of the island. Geological Survey expeditions in early 2005 to measure the full extent of the tsunami that struck Sumatra. “So without a natural warning, without an official warning and with no history of tsunamis, hitting coastlines full of people, that’s the perfect combination to cause a lot of death and destruction.”īoth Borrero and Titov took part in U.S. “ came ashore in these places that had no natural warning either, because they were far enough away that they didn’t feel any of the earthquake,” says Borrero. “Almost no injuries, because it’s such a difficult disaster to survive.”Īn earthquake and tsunami of the magnitude that struck in 2004 is so rare that catastrophic tsunamis are all but unknown in the long cultural histories of India and Sri Lanka, explains Jose Borrero, a tsunami researcher with the University of Southern California and director of eCoast, a marine consultancy based in New Zealand. ![]() It’s completely reversed with tsunamis,” says Titov. “In earthquakes, a certain number of people die but many more are injured. Once caught in the raging waters, if the currents don’t pull you under, the debris will finish the job. “It’s more like the ocean turns into a white water river and floods everything in its path.” “It’s a wave, but from the observer’s standpoint, you wouldn’t recognize it as a wave,” Titov says. Titov emphasizes that tsunamis look nothing like the giant surfing break-style waves that many of us imagine. The effect was like dropping the world’s largest pebble in the Indian Ocean with ripples the size of mountains extending out in all directions. In the process, massive segments of the ocean floor were forced upward an estimated 30 or 40 meters (up to 130 feet). Rather than delivering one violent jolt, the quake lasted an unrelenting 10 minutes, releasing as much pent-up power as several thousand atomic bombs. The 2004 quake ruptured a 900-mile stretch along the Indian and Australian plates 31 miles below the ocean floor. ![]() “They are the largest faults in the world and they’re all underwater,” says Titov. The quake originated in a so-called megathrust fault, where heavy oceanic plates subduct beneath lighter continental plates. He credits the unsparing destructiveness of the 2004 Indian Ocean tsunami on the raw power of the earthquake that spawned it. Vasily Titov is a tsunami researcher and forecaster with the National Oceanic and Atmospheric Administration Center for Tsunami Research. But some of the worst devastation was reserved for the island nation of Sri Lanka, where more than 30,000 people were swept away by the waves and hundreds of thousands left homeless.Īs proof of the record-breaking strength of the tsunami, the last victims of the Boxing Day disaster perished nearly eight hours later when swelling seas and rogue waves caught swimmers by surprise in South Africa, 5,000 miles from the quake’s epicenter. The death toll in Thailand was nearly 5,400 including 2,000 foreign tourists.Īn hour later, on the opposite side of the Indian Ocean, the waves struck the southeastern coast of India near the city of Chennai, pushing debris-choked water kilometers inland and killing more than 10,000 people, mostly women and children, since many of the men were out fishing. Curious beachgoers even wandered out among the oddly receding waves, only to be chased down by a churning wall of water. Despite the time-lapse, locals and tourists were caught completely unaware of the imminent destruction. With waves traveling 500 mph across the Indian Ocean, the tsunami hit the coastal provinces of Phang Nga and Phuket an hour and a half later.
