Context
Japan is located along the Pacific Ring of Fire, a highly active seismic zone prone to frequent earthquakes and volcanic eruptions. The country has a robust earthquake monitoring and early warning system, including the Japan Meteorological Agency (JMA), which issues alerts for seismic events. Tsunami warnings are typically issued if an earthquake's magnitude exceeds 7.0 or if its epicenter is underwater, generating potential waves. Japan experiences thousands of earthquakes annually, though most are minor and cause little to no damage.
