Earthquake correction


I thought it felt a little bigger than 5.3.... the Taiwan central weather bureau, monitoring agency for the more than one hundred seismometers stationed on the island, have reported the earthquake from the other night at 6.0

USGS, using a global array and being positioned on the opposite side of the globe, have considerably less constraint on the near-field data of the event... I tend to trust the local knowledge... after all, the Taiwanese are experts on seismicity almost by default of living smack in the middle of not one, but two active subduction zones and one of the most active subaerial orogenic wedges on the planet. Even the USGS seismic hazard map for Taiwan shows almost the entire island scoring off the chart on predicted seismic activity.
