Pacific-North American Plate Stress Update MT Observations Taken at 10:00 UTC

[Frank Condon]

Hello all:
The latest observation are indicating a number of MT excursions have taken place during the past 24 hours, which began just prior to the M6.3 earthquake epicentered in the Gulf of California. The latest excursion was detected at 10:27 UTC. These are atypical, and in negative territory when compared to those of the past. It's similar to a piezo-magnetic pulse with a large negative polarity. For a couple of hours prior to the M6.3 seismic event, a high frequency ULF burst was also detected. The duration of these MT excursions remains very short at approximately one second. Possibly it's related to the recent seismic activity in the Gulf of California, and the nucleation process as stress moves further north along the plate boundary and into Southern California. This is something new to report, and it needs to be monitored very carefully.
