Strangemaps shows San Francisco immediately post '06 quake. I love comparing old geography to modern geography, to see how humans have changed things. Look how China Basin once had so much water, and is now mostly filled in.
The epicenter (long thought to be at Olema, at the neck of Point Reyes) was actually a bit left of where the P in "Pacific Ocean" is, on this map, just offshore where the San Andreas goes into the sea near the Daly City/SF line.
Earthquakes simultaneously fascinate and terrify me. I can read just so much about them, and then I have to stop. Seismology is one of my favorite hobby fields, but I don't think I could study it as a focus in geology without becoming a gibbering mass of anxiety.
