An 8.7-magnitude earthquake occurred near Russian waters, triggering a tsunami warning.

An 8.7-magnitude earthquake occurred near the Kamchatka Peninsula, causing a tsunami that has already flooded areas near the coast of Hokkaido, Japan. Americans predict that tsunamis over 3 meters high may occur along the coasts of Russia and Ecuador, while tsunamis between 1 and 3 meters high may occur in Japan, Hawaii, Chile, and the Solomon Islands.

Japan is located on the Pacific Ring of Fire, at the junction of the Pacific Plate, Eurasian Plate, Philippine Sea Plate, and North American Plate. The mutual compression and subduction of these plates, especially the subduction of the Pacific Plate beneath the Eurasian Plate, leads to the accumulation of crustal stress, which frequently triggers strong earthquakes. When a strong earthquake occurs on the seafloor, sudden vertical displacement of the seafloor pushes a large amount of seawater, forming a tsunami wave. The 2011 Japanese 9.0-magnitude earthquake caused a slip of more than 50 meters along the plate boundary fault, triggering a tsunami with waves over 40 meters high. In comparison, this tsunami is much smaller.
