Rhode Island’s top environmental official says scientists trying to figure out the cause of a mysterious beach blast that sent a woman flying into a jetty are now pursuing a specific cause.

Coit says scientists took core samples of the beach sane where the incident occurred and the sand at the site of the incident had unusually high levels of hydrogen.

“I would take my kids there”, said Arthur Spivack, an oceanographer at the University Rhode Island, who helped conduct the review.

The victim, Kathleen Danise, 60, of Waterbury, Conn., landed on the rock jetty next to where she was sitting in her beach chair and suffered a cracked rib and some bumps and bruises.

The explosion injured a woman. Explosive sniffing dogs and equipment similar to devices used by the Transportation Safety Administration didn’t register a whisker of evidence along those lines, said Rhode Island State Fire Marshal John Chartier. Dispatchers began sending a response and the caller said “I heard a bang”.

In a statement, Rhode Island Governor Gina Raimondo said she and others are grateful for the work of the “extraordinary scientists at URI”.

Since determining the likely cause of the incident, DEM has removed the source of energy, aerated and swept the area, and the beach is safe and open to the public. “There was coordination and collaboration around the investigation from Colonel Steve O’Donnell and the RI State Police, the State Fire Marshal, USDA’s Natural Resources Conservation Service soil scientist Jim Turenne, and other state and federal government officials”. Just days after the blast, officials dug up an old Coast Guard cable from under the surface of the sand.

“The talented scientists at our world renowned Graduate School of Oceanography at URI have given us an explanation for what happened when the ground shook at our beach”, said Coit.

The Coast Guard does not believe there are cables underneath any other beaches in the state, Oldham said.
