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.^[1] A Seattle Mariners game was in progress when the quake hit, and play was temporarily postponed to verify no structural damage to the Kingdome.^[2] 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.^[3]
