The data are now starting to make some sense.

The recent strong EM Signal matches several earthquakes that occurred the day before. That also happened with the signal detected on July 3.

Something is generating EM Signal energy. That energy then interacts with fault zones where earthquakes recently occurred. And the types of EM Signals that I work with are then generated.

So, the question is, what is it that is generating that original EM Signal energy. Solar storms are likely involved. But there is something else involved as well. It might be that continuing Popo volcano activity. But more likely it is an approaching strong earthquake.

The July 3 signal was a fairly good match for the PNG aftershcck that occurred a few hours after that recent 7.3 magnitude PNG earthquake. The original earthquake was quite deep. The aftershock was much closer to the surface.

Anyway, those are the present "working" theories.

These are personal opinions.
