Chile Earthquake 27/02/2010 Recorded at Keele

A very large earthquake, at 8.8, the sixth largest since modern seismic recording began around 1900, has struck off-shore southern Chile. More details from the USGS and Ole Nielsen.

At 107° epicentral distance, Keele is just in the shadow zone so the direct P and S-waves are not recorded. However, even at a distance of almost 12,000 km our seismometer went off-scale during the surface wave arrivals.
