The M5.4 quake is strike-slip with a little extension (slightly oblique normal).
Canie, Glen, comments? I recall that Canie thought that Baja and/or Gulf of California quakes tended to be followed by Salton Trough quakes or something like that, but not sure I have seen that relation work. Not sure if this would be considered in part of Salton Trough or not.
I hit the google earth map link and did not see any obvious fault near this quake. The maps at this site do not show any good fault map, but theer are big ones related to the San Andreas that must come through here somewhere. I need to find my California fault map and keep it at home.
