Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake.
Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake.
The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists from Tokyo Tech. This work highlights the need for more precise tsunami prediction technologies to prepare for future events.
In 2024, a 7.5 magnitude earthquake struck the Noto Peninsula in Japan on New Year's Day, causing strong shaking, landslides, fire, liquefaction, land uplift, and devastating tsunamis. Ishikawa Prefecture, the hardest hit area, saw at least 241 fatalities, and about 75,187 houses damaged. Although the Noto Peninsula has experienced frequent earthquakes and tsunamis in the past, the 2024 tsunamis were different.
