South Andros Island, part of the Bahamian archipelago, is a sandy slice of paradise whose shores conceal buried geological treasures: blue holes. Hiding in the depths of these ethereal submarine sinkholes lay ancient sediment sandwiches whose layers betray the bygone passages of powerful hurricanes.
Researchers have assembled a 1,500-year history of hurricanes in the Bahamas, based on sand and shell fragments pulled up from submarine caverns known as blue holes.
The study says that stormquakes are actually a fairly common occurrence, but they just sounded like seismic background noise and went undetected.
Over the past year and as a student fellow in 2017, I have been working with Woods Hole Oceanographic Institution scientist Jeffrey Donnelly, who uses sediment cores—tubes of sand and mud layers that are extracted from coastal lake beds—to track ancient cyclones in the Atlantic and, recently, in the islands of the South Pacific.
In the 81 years since the 1938 storm, the sea level here has risen about a foot, said WHOI researcher Jeff Donnelly, and is now rising faster than it has in thousands of years.

BBC radio host Rhod Sharp and Jeff Donnelly of WHOI’s Coastal Research Lab trace the history of hurricanes in the Atlantic and discuss the frequency of intense storms. New sediment records indicate that historically unprecedented levels of intense hurricane activity impacted the eastern seaboard of the United States and northeastern Gulf Coast in the last two millennia.

With Hurricane Florence bearing down on the North Carolina coast, researchers at Woods Hole Oceanographic Institution (WHOI) have mobilized autonomous vehicles and instruments to track changes in the ocean ahead of and beneath Florence.Read More
