Seismic Cluster Strikes Offshore Oregon

Larger Shocks May Occur

Cluster of at least 9 shocks strike offshore Oregon

Earthquake measuring about 5.4Mw struck the offshore Oregon about 500km west of Eugene on Friday, May 07, 2010 at 17:46:15UTC.

Epicenter of the earthquake was located near 44.396°N, 129.437°W and occurred at a depth of  10 km (6.2 miles). The initial shock was followed by at least 8 other events [aftershocks] measuring a mean magnitude of about 4.4Mw.

Center of the cluster was about 1,000km (600 miles) south of  a magnitude 8.1 shock that occurred on the Queen Charlotte Fault off Queen Charlotte Island on August 22, 1949. That event was Canada’s largest earthquake since 1700.
