This earthquake advisory is based on strong EM Signals that were detected at the following times, both UTC:

2011/11/12 15:45:00
2011/11/12 14:44:00

75% of the time when two strong signals are detected within a few hours of one another like that it is an indicator to me that the approaching earthquake responsible for the signals will occur within 5 days.

However, in this case the data clearly pointed to specific likely locations. And I have been watching for a powerful earthquake to occur along one of the following longitude lines:

115W 25W 65E 155E

There has not been any significant activity along any of those longitude lines as far as I can tell. And since that 5 day window is over, this advisory is just being posted to cover the 25% possibility that the expected earthquake is going to be delayed.

There is also the possibility that the signals were related to recent activity in the Hierro volcano at 18W. Volcano activity related EM Signals appear to be much stronger than the earthquake related ones. And I don’t yet know if the volcano longitude would be accurately reported by my forecasting computer programs.

I especially hope that there won’t be a significant earthquake along the 65E longitude line in the near future as I believe that ones there can be fairly destructive.

Time will tell with this one.
