Fault Plane Solution for this event showing that the earthquake occurred along a north-south or east-west strike slip fault.

SeisComP3 scmv (map view) display as few minutes after the event. The triangles with red and green borders are stations where Seiscomp has detected and picked a P wave arrival. the color of each triangle indicates ground motion. Note the orange and red triangles in northern Europe and Greenland closest to the epicenter where the ground motion is highest.

Azimuth: 31.2 Deg.

SeisComP3 traces for AM.R8C73.00.SHZ (Exton PA), LD.WUPA.BHZ (West Chester University, West Chester PA), and LD.GEDE.BHZ (Greenville DE) showing the P wave arrivals. Filtered with a 3rd order Butterworth bandpass filter with corner frequencies of 0.7 and 2 Hz,

This event had a highly impulsive P wave as seen in these unfiltered traces from AM.R8C73.00.SHZ and LD.WUPA.BHZ.

These Jamaseis Heliocorder traces also show the impulsive nature of P waves for this earthquakes. Note that for LD.WUPA.BHZ the P wave amplitude exceeds that of the strongest surface waves.

SeisComP3 scolv display showing the fault plane solution for this event. This varies somewhat from USGS solution, but both show a similar focal mechanism.
