Kantō earthquakes
A Kantō earthquake (関東地震, kantō jishin) is a megathrust earthquake occurring in the Kantō region of Japan that originate from slippage in the Sagami Trough. Kantō earthquakes are thought to occur with a 200-year return period.
Only two earthquakes in the Kantō region are thought to be megathrust earthquakes:
- 1923 Great Kantō earthquake; most common usage
- 1703 Genroku earthquake
Other earthquakes in the Kantō region, which may or may not be due to slippage in the Sagami Trough:
- The Ruijū Kokushi mentions an earthquake that struck the area in 818
- 1855 Edo earthquake
A future "big one" striking Greater Tokyo. Not to be confused with future Nankai megathrust.
