The tsunami struck Higo Province on the other side of Ariake Bay before bouncing back and hitting Shimabara again. Out of an estimated total of 15,000 fatalities, around 5,000 are thought to have been killed by the landslide, around 5,000 by the tsunami across the bay in Higo Province, and a further 5,000 by the tsunami returning to strike ...
Giant landslides and collapses of ocean island volcanoes were first described in 1964 in Hawaii and are now known to happen in almost every ocean basin. [1] As volcanoes grow in size they eventually become unstable and collapse, generating landslides [2] and collapses such as the failure of Mount St. Helens in 1980 [3] and many others. [4]
Before and after imagery also helps to reveal how the landscape changed after an event, what may have triggered the landslide, and shows the process of regeneration and recovery. [ 50 ] Using satellite imagery in combination with GIS and on-the-ground studies, it is possible to generate maps of likely occurrences of future landslides. [ 51 ]

Storegga tsunami deposits (grey upper layer), bracketed by peat (dark brown layers), taken at Maryton on the Montrose Basin, Scotland. At, or shortly before, the time of the Second Storegga Slide, a land bridge known to archaeologists and geologists as Doggerland linked Britain, Denmark and the Netherlands across what is now the southern North Sea.
The landslide, which took place last year in September, triggered a massive tsunami in Dickson Fjord, creating puzzling tremors and a planet-wide “hum”, scientists said.
On 17 June 2017, a landslide measuring 300 m × 1,100 m (980 ft × 3,610 ft) fell about 1,000 m (3,280 ft) into Karrat Fjord, generating a megatsunami that hit Nuugaatsiaq. [ 2 ] [ 3 ] [ 4 ] Initially it was unclear if the landslide was caused by a small earthquake (magnitude 4), [ 2 ] [ 5 ] but later it was confirmed that the landslide had ...
“It requires an 8.7 to get a tsunami all the way to Japan,” Tobin said. The people who recorded the incident in Japan couldn’t have known that the ground had shaken an ocean away, in the ...
