Alaska Earthquake Rattles Florida’s Groundwater Plumbing
Release Date: JANUARY 24, 2018
At 12:32 am Alaska time on January 23, 2018, a magnitude 7.9 earthquake shook Alaska residents out of their beds and set off fears of a tsunami all down the West Coast. Fortunately, the tsunami was only a few inches in height, but within an hour of the earthquake in Alaska, waves of a different sort were hitting far away in Florida. 

More than 3,500 miles from the Kodiak Earthquake’s epicenter, water levels at the USGS groundwater well near Madison, Florida, spiked by about two inches, while levels at the USGS groundwater well near Fort Lauderdale, Florida, dropped by an inch and a half. Both recovered to their previous levels within an hour.

Hydrographs from two USGS groundwater monitoring sites in Florida show effects on groundwater levels from the M7.9 earthquake near Kodiak, Alaska.
