The cable that caused an explosion at a crowded Rhode Island beach last summer, injuring a woman, may have counterparts lying under beaches, harbors and waterways at dozens of sites nationwide.
There are 48 sites in 12 states where Coast Guard lights -- in lighthouses, buoys, or other beacons -- were converted to solar power, but sub-cables that used to power them are still in the service's database.
The Coast Guard provided a list to The Associated Press in response to a records request.
The cables' presence in the database indicates they're probably still there, though there's no way of knowing for sure without digging.
Scientists say the explosion at Salty Brine Beach in Narragansett, Rhode Island, was probably caused by hydrogen that built up around a corroded Coast Guard cable.
