Easter Sunday Earthquake
I estimate that this magnitude 6.9 quake epicenter was over 250 miles from here. It made the ground bump and roll slightly and the wind chimes sounded as well as all hanging chandeliers were wobbling. Looking at the fault map, I believe this was along the southern San Andreas fault group. There is a Mexican village called Guadalupe Victoria about 16 miles away that probably got it pretty hard. Moderate to strong shaking and damage reported in Yuma, AZ.
A strong earthquake occurred at 3:40:39 PM (PDT) on Sunday, April 4, 2010.
The magnitude 6.9 event occurred 26 km (16 miles) SSW of Guadalupe Victoria, Baja California, Mexico.
The hypocentral depth is 32 km (20 miles).
Update: USGS now says magnitude 7.2.

In Rancho Penasquitos (NE San Diego city limits) it was moderate, chimes banging together in the clock, water shaking in the pool, a couple of items fell over on the bureau, etc. No broken dishes or anything fallen off the shelves.
Still, one of the strongest quakes felt in years in the San Diego area.
Aftershocks still rolling through now at 1625 hrs/4:25pm.

I worried that communities near the border might be hit. Glad that it doesn’t seem too bad there.
Folks in Calexico and Brawley report some damage and there was a magnitude 5 aftershock - epicenter near Imperial.

Looking at the USGS Earthquake List for the location, Guadalupe Victoria seems to have been shaking non-stop for the last day or three.

Many years ago, I flew a helicopter transporting a USGS crew whose charter was to measure land shift in the Salton net - the very area where these quakes happened. I would carry one of the crew to the top of several mountains along the valley where they would set up a laser emitter over a USGS marker. They would project the beam to other hilltops in the area and record the angles to calculate the recent movement.
This place, like Parkfield on the San Andreas in central California, has almost constant microquake activity.

Wow, 7.2 - pretty big. Could have caused quite a bit of damage in highly populated areas I think. My guessd would be that the town it was closest too suffered badly. I experienced quite a few of these when I lived in Calexico, luckily I was always outside and never was injured. Never one that big though. I think my biggest was about 6.2.
All the best,

We rocked and rolled (mostly rolled) here in Long Beach for what felt like several minutes. Longest one I’ve felt. Fairly gentle, but it just kept going…..
