Japan accounts for about one-fifth of the world’s earthquakes of magnitude 6 or greater, according to Reuters.The country lies along the Pacific “Ring of Fire”, a vast zone surrounding the Pacific Ocean where several tectonic plates meet. The region is responsible for about 90% of the world’s earthquakes and is the planet’s most active seismic zone.Japan experiences thousands of small tremors each year, along with hundreds of moderate-to-strong earthquakes measuring magnitude 4 or higher.The JMA says earthquakes above magnitude 5 can make it difficult for people to walk without holding on to something stable, while unsecured furniture may topple over.
