Earthquake  detected on Earth Tide signals in Texas and Florida

Note: First ever power grid quake detection on land shown below.


Panama area 5.1 M gives a nice clean pulse on the Earth Tide Trace 0- 100 uHz.  About an hour long pulse.  Electronically received time wise, not the usual mechanical long time propagation of earthquake machines.

The same time in Texas produced a very small detection but on a much different distance and path. See on the lower plot.


-First Power Grid detection of Earthquake on land-

Texas station recorded this 2.9 M from near by Oklahoma


Two hours later a second quake in Nevada following the one in Oklahoma.
