Japan's earthquake rocked Texas aquifer

When the earth shook during the March 11 earthquake off Japan, it had enough force to move water deep inside the Edwards Aquifer in Central Texas.

Within 15 minutes of the magnitude-9.0 earthquake, the Edward Aquifer Authority's J-17 monitoring well in Bexar County started to vibrate, with the water level fluctuating about a foot.

"It moved up and down for almost two hours," said Roland Ruiz, a spokesman for the water authority. "We thought it was certainly interesting that a quake that far away would register in the aquifer."
