Early detection of the #1 earthquake occurred on September 15, 2010 9PM (see ATS post above)
#1 earthquake strikes September 16, 2010 at 04:41:33 PM at epicenter
Piezoseismic reading 16.5 Outdoors, and 6.5 Indoors
18+ hours minimum advance warning detection occurred for a small M3.3 earthquake from 150+ miles
Early detection of the #2 earthquake occurred on September 19, 2010 2AM (see ATS post above)
#2 earthquake strikes September 19, 2010 at 05:01:47 PM at epicenter
Piezoseismic reading 14 Outdoors, and 6 Indoors
15+ hours minimum advance warning detection occurred for a small M3.5 earthquake from 150+ miles
* The piezoseismic system is only fired up once a day for less than 5 minutes on any given day; unless an earthquake is being tracked down to its
epicenter.
As you will notice from the above, the M3.3 earthquake has just a little weaker piezoseismic value than the M3.5 earthquake even though they are
basically from the same distance away. This proves that magnitudes are determinable before earthquakes strike (a lower piezoseismic value in the same
range means the signal is stronger, meaning that a stronger earthquake detected at the same range should have a stonger value as is shown above).
