The moderate tremor at a depth of about 4.9 miles and was centered about 66 miles northeast of Shibetsu, located in western Hokkaido.
Several weeks ago, a 6.6 magnitude earthquake struck off Hokkaido, causing landslides, destroying buildings, and killing 40 people, AFP noted.
Japan sits along the Pacific “Ring of Fire” and is particularly earthquake-prone. In March 2011, a 9.1 magnitude quake triggered widespread damage, killing at least 15,000 people while crippling the Fukushima Daiichi power plant, forcing the evacuation and permanent relocation of thousands of people within an approximately 10-mile radius from the plant.
“The Ring of Fire isn’t quite a circular ring. It is shaped more like a 40,000-kilometer (25,000-mile) horseshoe. A string of 452 volcanoes stretches from the southern tip of South America, up along the coast of North America, across the Bering Strait, down through Japan, and into New Zealand. Several active and dormant volcanoes in Antarctica, however, ‘close’ the ring,” according to National Geographic.
