Earthquake in Japan
Earthquakes are common in Japan, which sits on the Pacific “Ring of Fire,” an arc of intense seismic activity that stretches through Southeast Asia and across the Pacific basin.
The country has strict construction regulations intended to ensure buildings can withstand strong earthquakes, and emergency drills are routinely held to prepare for a major jolt.
