The Lituya Bay megatsunami caused damage at higher elevations than any other tsunami, being powerful enough to push water up the tree covered slopes of the fjord with enough force to clear trees to a reported height of 524 m (1,719 ft). [9] A 1:675 recreation of the tsunami found the wave crest was 150 m (490 ft) tall. [14]
The height of the tsunami was limited due to relatively shallow sea in the area of the impact; had the asteroid struck in the deep sea the megatsunami would have been 4.6 kilometres (2.9 mi) tall. Among the mechanisms triggering megatsunamis were the direct impact, shockwaves, returning water in the crater with a new push outward and seismic ...
A magnitude 7.6-7.7 earthquake struck near the coast of western Mexico on 19 September 2022. A tsunami about 1.75 m (5.7 ft) high was reported near the epicentre. [209] The tsunami was detected as far away as Ecuador, where tsunami waves as high as 12 cm (4.7 in) were observed. [210] 2023 Greenland 2023 Greenland landslide: Landslide
They were among the 31 Europeans who died in the earthquake and tsunami. [6] [7] Right after the earthquake, a large tsunami reportedly swept through the coast of the island. On the Hitu peninsula, the waves were thought to be as high as 100 metres (330 ft), nearly topping the coastal hills. Entire forests and plantations were uprooted and ...
The Okushiri, Hokkaidō tsunami, which struck within two to five minutes of the earthquake on July 12, 1993, created waves 30 metres (100 ft) tall—as high as a 10-storey building. The port town of Aonae was completely surrounded by a tsunami wall, but the waves washed right over the wall and destroyed all the wood-framed structures in the area.
The tallest tsunami was recorded 1.34 m (4 ft 5 in) at Amami Ōshima, Okinawa. [115] Tsunami waves of less than a metre were reported along the Hokkaido Pacific coast. [116] The JMA said that the tsunami struck 2.5 hours earlier than predicted. [117] Small tsunami waves were observed on the coast of Taiwan.
At Port Blair, the water receded before the first wave, and the third wave was the tallest and caused the most damage. Results of the tsunami survey in South Andaman along Chiriyatapu, Corbyn's Cove and Wandoor beaches: [citation needed] 5 m (16 ft) in maximum tsunami height with a run-up of 4.24 m (13.9 ft) at Chiriyatapu Beach
Okushiri had been struck by another tsunami 10 years earlier. A maximum run-up of 32 m was recorded on the western part of the island near Monai. A tsunami was widely observed in the Sea of Japan with a run-up of 3.5 m at Akita in northern Honshu, up to 4.0 m in southeastern Russia and up to 2.6 m on the coast of South Korea. [9]
