Around 9:25pm tonight, as I was doing the blog thing on the computer, I heard the ceiling light fixture rattling just a tad and, simultaneously, also noticed my potted anthurium swaying without rhyme, reason, or a breeze.
Lasted probably around 30-60 seconds (i.e, about a minute). There's been a recent swarm of minor earthquakes in and around the area of Anza Borrego Desert SP (E. San Diego County). In checking the USGS website, a 5.7 magnitude earthquake did occur about 5 mile SE of Ocotillo at 9:26:58pm this evening http://earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/ci14745580.php
All of us here in California are bracing for the big one along the San Andreas Fault, and you just never know what might be a precursor. Not freaked out, but just waiting with baited breath.
