8.8 Earthquake Struck Off Russia’s Kamchatka Peninsula: A powerful undersea earthquake measuring 8.8 on the Richter scale struck off Russia's Kamchatka Peninsula early Wednesday, setting off a series of seismic aftershocks across the region. According to the United States Geological Survey (USGS), the initial quake struck at a depth of 74 kilometres below the ocean floor. Its impact was strongly felt in Severo-Kurilsk, Petropavlovsk-Kamchatsky, and several surrounding settlements across Sakhalin.
What Is Tsunami?
Tsunamis are large ocean waves generated by sudden vertical shifts in the seafloor, often due to powerful earthquakes along shallow faults or massive underwater landslides. As these waves approach coastal areas and enter shallower waters, they grow significantly in height, according to the US Geological Survey (USGS).
