March 11 Japanese tsunami waves topped 40 meters (130 feet)

July 2, 2011JAPAN – Japan’s massive tsunami on March 11 reached heights of up to 131 feet (40 meters), according to the latest data from Japan’s Meteorological Agency. That’s the agency’s best estimate, but the precise height will likely never be known because the earthquake and tsunami destroyed tide gauges and triggered blackouts and communication failures along the country’s coast. The 131-foot tsunami was recorded in Miyako City in Iwate Prefecture, reported the Japan Broadcasting Corporation.Other cities had wave heights ranging from 33 to 115 feet (10 to 35 m). The tsunami spread across the Pacific Ocean, hitting Hawaii and California. The tsunami was similar in height to the 2004 Indian Ocean tsunami, which killed an estimated 230,000 people in Indonesia. That tsunami reached heights of up to 98 feet (30 m), and was caused by an earthquake of between magnitude 9.1 and 9.3. Japan’s largest tsunami is believed to have hit the island of Kyushu, Japan, in May 1792, when one of Mount Unzen’s peaks collapsed during an earthquake and volcanic eruption. An avalanche fell into Ariake Bay, triggering wave heights of up to 330 feet (100 m). The landslide and tsunami killed 15,000 people. The largest tsunami in recorded history hit on July 9, 1958, at Lituya Bay on the southeast coast of Alaska. The wave is recorded at 1,720 feet(524 meters high), but because the area was relatively isolated and in a unique geologic setting, the tsunami did not cause much damage. It sank a single boat, killing two fishermen. Japan’s massive tsunami was caused by a magnitude 9.0 quake — the country’s largest ever recorded — which struck off the coast of Japan’s largest island, Honshu, on March 11. An estimated 30,000 people were killed during the earthquake and tsunami. When an earthquake ruptures along a fault line, the surface around that fault is pushed up and then dropped back down. That movement displaces the entire water column above that chunk of the surface. Not all undersea quakes generate tsunamis, as some occur so deep in the Earth’s crust that they won’t cause this push. –Amazing Planet

    super nice languaging dude!

    It’s very hard to imagine a wall of water that tall bearing down on anyone. The speed it was traveling must have been tremendous too!

    California next? California is riddled with many highly-active fault zones, and a great number of them have not seen major seismic activity for a long time. Based on the pattern of heavy seismic activity taking place around the Pacific “Ring of Fire” in recent months, which represents the patchwork of fault line-ridden land masses circling the Pacific Ocean, California appears to be next in line for a major shaker.

    Mother nature is great……
