Hi All,

I was scanning through the messages on the OES site to see what they issued yesterday for the MTJ quake and found this one on the Geysers which clearly states it was triggered by the MTJ event...I thought you might want to see it..Petra

PRELIMINARY EARTHQUAKE REPORT
California Integrated Seismic Network

USGS/Caltech/CGS/UCB/UCSD/UNR

Version 2: This report supersedes any earlier reports about this event.

This event was reviewed by the USGS on-duty seismologist.

This quake was triggered due to the passage of the seismic waves of
the Mw7.1 Mendocino quake. The initial magnitude of 5.1 was incorrect
because
the amplitude reflected the seismic waves of the Mendocino quake.
