4.6 magnitude earthquake jolts many residents awake early Friday morning

A 4.6 magnitude earthquake centered about 2 miles northwest of Monroe, WA shook many Snoqualmie Valley residents awake early Friday morning, July 12, 2019.

The moderate earthquake happened at 2:51AM and only lasted a few seconds, but based on social media posts, woke up hundreds in the upper Snoqualmie Valley.

According to the Pacific Northwest Seismic Network, the earthquake was centered about 14 miles deep. Two minutes later a smaller, 3.5 magnitude quake occurred just to the southwest and was about 5 miles deeper.

Over the course of the following hour, multiple small aftershocks happened in the same area – ranging from .9 to 1.7 magnitude. [See location map below.]

People reported feeling the earthquake from Vancouver B.C. to Wenatchee to Olympia. [See USGS ‘Felt It’ map below.] A Duvall area resident said a ‘distinct sound’ accompanied the quake. Three of the four sleeping people in our Snoqualmie home were awakened by the shaking.

The earthquake triggered a Snoqualmie homeowner’s motion-activated security camera, which captured a little bit of the shaking. Video below:
