Video captures intensity of 7.2 Mexicali earthquake

The intensity of last month's magnitude 7.2 earthquake in Mexicali, Mexico, was captured in a videotape released by the U.S. Geological Survey.

The video was taken a ways from the epicenter in Devils Hole, Nev., in Death Valley. The U.S. Geological Survey video was taken by two video surveillance cameras positioned approximately 4 feet above the water surface and one underwater.

According to the USGS: "The water at Devils Hole is generally very still and although clear, quite stagnant. Thus, the movement seen in this video is thought to represent a fairly great disturbance to the shallow feeding/spawning shelf. The shelf substrate, consisting largely of sand, gravel and cobble was largely redistributed as a result, changing the topography fairly drastically. The entire video (not shown) shows fish returning to the shelf starting about five minutes after the water movement ceases."

The temblor -- the strongest to shake the Baja California region in nearly two decades, killed two people and damaged scores of structures.

On the California side of the border, the quake did an estimated $91 million in damage.
