The 1996 Duvall earthquake hit Duvall, Washington, about 25 miles North East of Seattle, at 9:04pm (PDT) on May 2. It hit with magnitude 5.6, and could be felt all over western Washington, northern Oregon, southern British Columbia, and east to Wenatchee. The earthquake was 5 miles (7 km) deep. A Seattle Mariners game was in progress when the quake hit, and play was temporarily postponed to verify no structural damage to the Kingdome. At least 45 aftershocks of a magnitude 2 or higher were reported in the subsequent days following the quake. This was the biggest earthquake in Washington since April 1965 until the 2001 Nisqually earthquake.
