Virginia earthquakes slide down the megathrust

I'm having more confidence in their depth calculations, since they must have some decent seismometers by now.  They have just had an earthquake that is 16 km deep, which is very unusual for a small earthquake, since this won't be felt, and is difficult to detect.

This has happened way down on the gently dipping megathrust.  If there were to be more of these, I would say it is setting up for an M7.  The lake water cannot be turned off, and continues the stress corrosion of the silicates.

As for timing, who knows?  Probably not for Christmas.....
