Most of them are in the 2.5 - 3 range and in the Westmoreland/Imperial region. Are there any Dopers who live in that area?
In the meantime, a 6.4 happened within the past hour in Tonga.
I like this seismograph, which is in someone’s basement in Lincoln, NE.
Well that was interesting in a way. I didn’t realize that the “vertical” lines running through the scroll were ticks made by the stylus at every minute. I guess I just always pictured a siesmograph drum as having those in spite of having seen images of siesmographs plenty of times.
There were 3 earthquakes in the magnitude 3 range in Milpitas, just west and north of San Jose and south of where I live. We felt one, lots of people around here felt others. Nothing major yet, but it does make me nervous.
