I think plate tectonics, volcanoes and geology in general is most interesting, so yes but not out of great concern for your son. Unfortunately, earthquakes can only be generally predicted within an area. A "based on history and geology, you can expect so and so" sort of a thing. The San Francisco area is far better prepared for a bad earthquake than most of the world. Up here in the Pacific Northwest, we are far less prepared but we will eventually have a large destructive quake.

It hasn't cost me any sleep.

I'm watching "Tsunamis: Megadisasters" on the History Channel, presently.

Maybe I'll just go to bed.

Howdy Neighbor.

Did you see those 2 micro quakes 14 miles off of Newport last week.

Been here watching USGS for 20 yrs and that is the closest action I have seen.
I have felt two offshore (IIRC about 100 miles) in the last ten years or so.

I just shake my head when looking a those homes on the sand spit up in the Taft area with the Tsunami warning signs adjacent on Hwy 101.
