They are especially dangerous in harbors where the water can become trapped and compressed, causing higher waves. In 1964, a massive 9.2 magnitude earthquake in Alaska resulted in a tsunami in ...

Should a similar earthquake happen today, scientists say a giant tsunami would wash away coastal towns, destroy U.S. 101 and cause $70 billion in damage over a large swath of the Pacific Coast.
Smaller (M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only a few minutes at a time. Landslides The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide.

The residents of the coastal towns and villages were taken completely by surprise because the tsunami had only been preceded by a relatively weak shock. The magnitude of the tsunami has been estimated as M t =8.2 while the earthquake shaking only indicated a magnitude of M s =7.2. This discrepancy in magnitude requires more than just a slow ...
