The first recorded tsunami in Japan struck on 29 November 684 AD off the coast of the Kii, Shikoku, and Awaji region. The earthquake, estimated at a magnitude of 8.4, [44] was followed by a large tsunami, but there are no estimates of the number of deaths. [60] From then on, the Japanese would keep meticulous records of tsunamis. [61] [citation ...
Lituya Bay has a history of megatsunami events, but the 1958 event was the first for which sufficient data was captured and was responsible for the deaths of 5 people. [ 9 ] [ 19 ] [ 17 ] A subsequent analysis to the 1999 one that examined the wider impact of the event found that the rockfall itself was inadequate to explain the resulting ...
A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres.The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2]
Khao Lak also experienced the largest tsunami run-up height outside of Sumatra. [91] [page needed] The highest-recorded tsunami run-up was measured 19.6 m (64 ft) at Ban Thung Dap, on the south-west tip of Ko Phra Thong Island and the second-highest at 15.8 m (52 ft) at Ban Nam Kim. [92]
It was the first detailed documentation of a tsunami in Indonesia and the largest ever recorded in the country. [1] The exact fault which produced the earthquake has never been determined, but geologists postulate either a local fault, or a larger thrust fault offshore. The extreme tsunami was likely the result of a submarine landslide.
Five died from the tsunami in Oregon, [14] and 12 died from the tsunami in Crescent City, California. [15] [16] Property damage was estimated at $116 million [3] ($0.87 billion in 2023 dollars). [17] United States Geological Survey video explaining the earthquake and footage

The earthquake measured a magnitude between 7.9 and 8.3 on the surface-wave magnitude scale, making it the largest earthquake recorded in Panamanian history. It struck the San Blas Islands and was strongly felt in the City of Colón as well as the capital of Panama City. The earthquake also produced a major tsunami that had a maximum run-up of ...
