Far out… I was just there on Sunday (blog entry coming). There has been a swam of 5 earthquakes near Julian, just down the road from us here at Temecula.

Yeah yeah, its pretty much exactly the same as the old one and yes, I am a little disappointed on just how similar it is, but eh, no going… Continue reading New seismograph

This is why I am glad to be part of the… Continue reading Seismic waves visualized.
