April 4 was the one-year anniversary of the magnitude 7.2 El Mayor-Cucapah earthquake in northern Baja California. Geology grad student Austin Elliott, is just back from 3 weeks of field work on the quakes effects and posted the first of a series on the aftermath on his blog, The Trembling Earth. He's got photos and videos I haven't seen before and promises to post quite a few more.
Austin has a video clip in his post showing a spectacular swimming pool seiche but that links to another 20 or so videos on YouTube, many showing swimming pools sloshing heavily in the ground shaking such as the one below. The quake occurred on Easter Sunday so there are a lot of home videos of family's celebrating that catch the action.
