余震

Aftershocks refer to the aftershocks of an earthquake, and are small earthquakes that occur after a strong earthquake. Aftershocks are attracting attention due to the recent increase in seismic activity in Japan. Increased seismic activity is considered a sign of tectonic movement, and aftershocks can increase the risk of earthquakes. Japan has a high risk of earthquakes, and information on aftershocks is an important element of evacuation plans and safety measures.
