The strongest earthquake yet in an ongoing “swarm” on the Kitsap Peninsula hit early Thursday, and hundreds of people reported feeling it.
A 3.6-magnitude temblor hit just over 2 miles outside Bremerton at 12:35 a.m. More than 700 people reported feeling it to the U.S. Geological Survey.
There had been 18 quakes in 24 hours, and the Pacific Northwest Seismic Network has recorded 42 tiny quakes since May 3.
The swarm is hitting on the western edge of the Seattle fault, which runs from western Kitsap County west to the Cascade foothills.
Seismologists believe the quakes are being caused by fluid moving underneath the Earth’s crust, KIRO reported.
“It’s interesting, but not alarming,” said Bill Steele with the Seismic Network.
