That's a very nice map, John. Thanks. I notice that the square symbols are for quakes "not in SCSN network." So, is this map as complete as the USGS versions for central and northern California?

Also, there appears to be a SCSN station well offshore of Point Concepcion. Pretty rough waters there! Do you suppose that station is actually where it's shown? On the seabed, perhaps? It's shown as near the epicenter of the large (M7.5?) 1927 "Lompoc" earthquake.
