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.
