Japan is on the 'Pacific Ring of Fire' and is used to frequent earthquakes. The 'Ring of Fire' is a collection of volcanoes in the Pacific Ocean. However, a big jolt raises the possibility of a tsunami. One such tsunami devastated Japan in 2011 after a 9.1 undersea earthquake. This was the most powerful earthquake ever recorded in Japan. 

The 2011 Japan tsunami killed 20,000 and caused the meltdown of three reactors at the Fukushima Daiichi nuclear plant.

Japan has three levels of issuing tsunami alerts — Tsunami Advisory, Tsunami Warning, and Major Tsunami Warning.
