Japan experiences tremors — both minor and major — almost every day, making it one of the most earthquake-prone countries in the world. The East Asian country sits on the “Ring of Fire,” where several tectonic plates converge, triggering many of the world’s earthquakes and volcanic eruptions.

Nearly 20% of global earthquakes measuring 6.0 or higher occur in Japan. Since 2011, when a 9.0-magnitude earthquake and tsunami triggered meltdowns at three reactors at the Fukushima Daiichi nuclear power plant, Japan has significantly strengthened its earthquake warning systems and evacuation protocols.
