At 13:17 (GMT) on July 12, an earthquake measuring magnitude 7.8 on the Richter scale struck near Okushiri Island off the coast of southwest Hokkaido, Japan. The earthquake and subsequent tsunamis that struck Hokkaido caused 197 deaths. As of July 27, 42 people were still missing.
The Japan Meteorological Agency (JMA) broadcast tsunami warnings for the coasts of Japan with a possible maximum tsunami height greater than 3 m soon after the earthquake occurred. Unfortunately, the earthquake occurred very close to Okushiri Island and the southwest coast of Hokkaido, and the warning was too late to save everyone.
