A tsunami surge of 64-centimetre (25 in) hit Norfolk Island and tsunami waves of 30-to-40-centimetre (12 to 16 in) hit New Zealand, while a much larger tsunami of 2.64 m (8.7 ft) in height hit Raoul Island, closest to the epicentre of the earthquake. 2021 Ambon Earthquake-triggered underwater landslide
The second and third waves came in 10 minutes intervals after the first wave. The third wave was the strongest, with a maximum tsunami wave height of 11 m (36 ft). Waves nearly three stories high devastated the Indian Air Force base, located just south of Malacca. The maximum tsunami wave height of 11 m (36 ft).
Amplitude, Wave Height, or Tsunami Height: Refers to the height of a tsunami relative to the normal sea level at the time of the tsunami, which may be tidal High Water, or Low Water. It is different from the crest-to-trough height which is commonly used to measure other type of wave height.
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 ...
Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). [8] Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). The narrow entrance of the bay has a depth of only 33 feet (10 m). [8]
Tsunami Calculated travel time map for the tectonic tsunami produced by the 1964 Prince William Sound earthquake in Alaska. Tsunami Travel Times computed using Tsunami Travel Times software v3.1 (P. Wessel). The map does not show the height or strength of the waves, only the calculated travel times.
The geological record of the region indicates on average, these mega earthquake and tsunami events happen every 500 years. This part of the US is at highest risk for a devastating tsunami Skip to ...
The tsunami at Ryōri Bay (綾里湾), Ōfunato reached a height of 40.1 metres (132 ft) (run-up elevation). Fishing equipment was scattered on the high cliff above the bay. At Tarō, Iwate, the tsunami reached a height of 37.9 metres (124 ft) up the slope of a mountain some 200 metres (660 ft) away from the coastline.
