UPDATED: What's shaking? A whole lot of (minor) quaking

UPDATED Dec. 10

Earthquakes come and go in this region, but a flurry of underground activity has shaken more than a few East Jefferson County residents. More than 40 tremors, mostly minor, have occurred in seven days around Pulali Point and Point Whitney along Hood Canal just north of Brinnon.

The bumps in the night late Dec. 5 and early Dec. 6 were noted in Port Ludlow, and on the “I’ve Heard of Quilcene” Facebook page on Friday morning.

Doug Gibbons, research scientist assistant for the Pacific Northwest Seismic Network (pnsn.org), said Dec. 10 that the small earthquakes are likely aftershocks of  a magnitude 3.5, which was felt around midnight Dec. 5. The coordinates given indicate the quake was east of U.S. Highway 101 near Boy Scout Camp Parsons, on the south side of Mount Walker and not far from Hood Canal.

All the quakes were recorded on land, not in the water, and were shallow, about 10 or 12 miles below the surface, Gibbons said.  He said they appear to have tapered off over the last few days with the last one recorded on Monday.

Shona Davis posted a note on the I’ve Heard of Quilcene Facebook page at 11:57 p.m. Dec. 5, asking whether she had just felt an earthquake. She said it got her out of bed.

“My house just shook, and for those of you who know my house, IT DOESN’T SHAKE!” she wrote.

Veda Wilson posted, “I felt it. Whopper.”

A number of people weighed in on the conversation, with some saying they felt it, and others saying they didn’t.

It seems the biggest quake may have been felt in Port Ludlow, too. Here’s a note from the Jefferson County Sheriff’s log: a Port Ludlow resident reported hearing a noise at the garage door at approximately 11:56 p.m., Dec. 5 in the 600 block of Montgomery Lane. Deputies arrived and noted signs of attempted entry. However, JeffCom 911 operators did report fielding calls of a small earthquake felt in Port Ludlow and Quilcene at the same time.

The Pacific Northwest Seismic Network recorded a flurry of activity in the same general area, late on Dec. 5 and early on Dec. 6, including those registering a 3.2, 2.8, 2.3 and 2.1.

"No, they're not big. But, if one person can feel one, well, that's big enough," said a Port Ludlow area resident about feeling a shake just before midnight.
