The National Weather Service is placing an increasing number of underwater sensors in the Atlantic, Caribbean and Gulf of Mexico to detect tsunamis.
The agency wants to increase its ability to spot an earthquake-generated tsunami and get a warning out to Floridians and other coastal residents.
But Florida State University professor Bill Dewar says there is a bigger concern than an earthquake-generated tsunami in the Gulf.
He says the northern Gulf, including the Panhandle coast, is made up of an unusual substance that could result in an underwater avalanche along the Continental Shelf during an earthquake.
He says that “slumping” could create an even larger tsunami than one created by an earthquake.
Meanwhile, the Weather Service is trying to get communities in Florida ready for tsunamis.
