BAY HEAD, N.J. (June 26, 2013)--A military explosives team took what's left of a suspected mine back to its shop to try to determine what it was and how it ended up partially buried in the sand in the ocean off New Jersey.
A plume of water shot about 125 feet in the air and a boom echoed through Bay Head on Wednesday as the team detonated the device with a 10-pound charge of C-4 explosives.
Naval Weapons Station Earle public affairs officer Michael Brady said the base's explosives ordnance disposal detachment believes it was just the detonation charge that exploded and not the mine.
Authorities evacuated about 15 homes and a quarter mile radius as a precaution.
Last year’s Superstorm Sandy may have exposed the device, Brady said.
The device was believed to be a contact mine from either World War I or World War II, base public affairs officer Brady said.
