Hydrologists report recording small spikes in the level of the Floridan aquifer following the earthquake, according to water management district officials.
"We did see a 2-inch spike that lasted six or seven hours," said Southwest Florida Water Management District spokesman Michael Molligan, although he added that analysts at the Brooksville-based district can't say with absolute certainty the spike was earthquake-related.
U.S. Geological Survey scientists estimate that seismic waves from the earthquake traveled across the globe at approximately 7,400 mph, causing small water-filled crevices in the Floridan aquifer to expand and contract. This action forced water in and out of the wells, scientists said....."And then the usual disclaimer...of course about no damage.
SNIP..."The hydrologists also concluded that no damage to the Floridan aquifer or water supply resulted from this event...."
