It's a full moon and the earth is shaking. Three small quakes within a hundred miles of Los Angeles in the past hour alone, according to the U.S. Geological Survey Web site.

Perhaps unscientific -- though seemingly never "gamed" or exagerrated -- is the USGS "shake map" at right. Within 30 minutes of tonight's 3.2 magnitude shaker centered near Granada Hills, over 700 people went to the site to report shaking intensity. Hover over the shaded counties on the original map to see the ZIP code detail, number of reports, and average intensity reported (also listed here).

Now, the USGS site rules, but don't confuse the efficiency of government technology / bells & whistles with its ability to react to disaster with any degree of efficiency. One would hope that, come the big one, USGS would also have a map of where to find food, water, or, heaven-for-bid, the Convention Center. Be prepared.

Did you feel it?
