A strong earthquake in Japan leaves 9 people with minor injuries. But there was no tsunami danger

TOKYO (AP) — A strong earthquake that struck southwestern Japan left nine people with minor injuries and caused damage such as burst water pipes and small landslides, authorities said Thursday. But there was no danger of a tsunami.

The magnitude 6.6 temblor late Wednesday was centered just off the western coast of the southwestern main island of Shikoku, in an area called the Bungo Channel, a strait separating Shikoku and the southern main island of Kyushu.

The quake occurred about 50 kilometers (30 miles) below the sea’s surface and posed no danger of a tsunami, the Japanese Meteorological Agency said.

The Fire and Disaster Management Agency said Thursday that six in Ehime prefecture, one in neighboring Kochi and two others in Oita on Kyushu island suffered minor injuries, mostly from falling at home.

Water pipes were ruptured at a number of locations in Sukumo City in Kochi prefecture, and grave stones collapsed at a Buddhist temple in Ainan town in Ehime prefecture, according to local media reports. Falling rooftiles were also reported.

The Nuclear Regulation Authority said that no abnormalities were reported from four reactors operating at three nuclear power plants in Shikoku and Kyushu.

As part of the Pacific “ring of fire,” Japan is one of the world’s most earthquake-prone areas. A magnitude 9.0 earthquake and subsequent tsunami in March 2011 devastated large areas along Japan’s northeastern coast, killing nearly 20,000 people and triggering the Fukushima Daiichi nuclear meltdowns. On Jan. 1, a magnitude 7.6 quake struck the north-central region of Noto and left 241 people dead.
