Tale of Two Seiches

The other day I noted the presence online of footage of the effects of a seiche at the Devil's Hole spring in Death Valley National Park as a result of the M7.4 earthquake in Oaxaca, Mexico, on March 20, 2012. That seiche event can be seen in the video immediately below: 




This event reminded me that a significant sized earthquake not that much smaller but certainly much closer that occurred on Easter Sunday two years ago (April 4, 2010) known as the El Mayor-Cucapah Earthquake likewise generated a notable seiche at the same Death Valley location which can be viewed below:




NOTE: No pupfish were harmed in the filming of these seiches.
