161 km S of ?yama, Japan

A magnitude 7.1 earthquake — a major event — struck near 161 km S of ?yama, Japan on August 9, 2009, at a intermediate-depth depth of about 292 km. An earthquake this size would have been felt strongly across the surrounding region; intermediate-depth events inside a subducting slab are often felt over a wide area but do less surface damage than shallow quakes. 433 people submitted "Did You Feel It?" shaking reports to the USGS. Casualties, damage and the recovery depend on local building standards, population and distance from the epicentre — the news coverage, references and photos below capture what happened on the ground.
