A loud explosion heard near Naval Air Station Whidbey Seaplane Base at around 10:30 a.m. Wednesday was part of a routine training exercise conducted by the Explosive Ordnance Disposal Detachment, according to base spokesman Mike Welding.

The Navy conducts the training a couple of times a month, but Welding said the low cloud coverage could have kept the sound closer to the ground resulting in a more clamorous explosion. Because the training is routine, the Navy did not notify nearby residents.

Jim Redding, who lives near the base on Silverlake Road, was checking his email in his home when he said the explosion rattled his windows and scared his dog.

“The explosion was a shaker,” he said.
