In a stretch of land 40 or 50 miles long north-south and maybe 10 miles wide, about 100 miles east of San Diego, there have been, in the last 13 hours and 30 minutes,

  • 38 earthquakes 3.5 to 3.9
  • 28 between 4.0 and 4.0
  • a 5.0 and 5.3
  • 7.2
The shaking from the 7.2 went on maybe 30 seconds, but nothing fell off the shelves where I am. One hopes this is releasing enough energy to put off the big one a while rather than putting more strain on the San Andreas to make it happen sooner.

Two good sites about earthquakes:
  • California Integrated Seismic Network. Pick northern or southern California for a list of all recent quakes 3.5 or bigger and links to a map of the earthquake area.
  • This is a map of California color-coded to the probability of an areas's experiencing a 6.0 or larger in the next 24 hours. Right now it looks like a sunrise over Calexico.

  1. Not good news for those of us in the Triple Junction ...regardless of how much the geologists claim that there is no proof one quake triggers another (outside off aftershock area).
