Seismic Activity in Japan
Japan lies at the intersection of four tectonic plates, making it one of the most seismically active regions on Earth with frequent earthquakes and tsunamis.
Understanding Earthquakes
- Magnitude 2.5-4.9: Minor earthquakes, usually felt but rarely cause damage
- Magnitude 5.0-5.9: Moderate earthquakes, can cause damage to poorly constructed buildings
- Magnitude 6.0-6.9: Strong earthquakes, can cause significant damage in populated areas
- Magnitude 7.0+: Major earthquakes, can cause severe damage over large areas
Stay Prepared
If you live in Japan, it's important to be prepared for earthquakes. Have an emergency kit ready, know safe spots in your home, and follow official guidance during seismic events.
Frequently Asked Questions
How often do earthquakes occur in Japan?
Japan experiences varying levels of seismic activity. Our real-time map shows all recorded earthquakes magnitude 2.5 and above.
How is earthquake magnitude measured?
Earthquakes are measured using the Moment Magnitude Scale (Mw), which replaced the Richter scale. Each whole number increase represents about 32 times more energy released.
What causes earthquakes in Japan?
Earthquakes in Japan are primarily caused by tectonic plate movement. The region's geological setting makes it prone to seismic activity.
