Vanuatu – M6.3 – Mar 20, 2019 at 15:23:58 UTC

52km E of Luganville, Vanuatu

Position: – 15.595°S 167.651°E  – Depth: 119.0 km

USGS Information Page

Distance from Exton PA: 120.5 Deg – 13,380 Km – Azimuth: 52.5 Deg

Detail of P wave arrival (no filter applied).

SeisComP3 traces for AM.R8C73.00.SHZ (Exton PA), LD.WUPA.BHZ (West Chester PA), and PE.PSUB.HHZ (Media PA) showing the P wave arrivals. There isn’t much to see here as only a weak spike was detected from this very distant event. Note however that the RaspberryShake (R8C73) was the only seismometer to actually generate an arrival in SeisComP3. The other two instruments, expensive lab grade seismometers at local universities did not generate arrivals in SeisComP.
