Um, it's a fact. Please do your research, before you post nonsense. There are no active earthquake faults with in hundreds of miles of the Oregon coast. There is no recorded record of any significant earthquakes on the Oregon Coast. The only way anybody could possibly have felt an earthquake near the Oregon Coast would be from a distant earthquake, and those would be so far away, the chances of anyone feeling it would be virtually zero.

BS, as usual. In earthquake years, the Cascade Subduction Zone is an "active earthquake fault."

Once again, I'll take the word of those who've studied this issue in-depth rather than the word of Cloudy-from-the-internet.

The Cascadia Subduction Zone has not produced an earthquake since 1700 and is building up pressure where the Juan de Fuca Plate is subsiding underneath the North American plate. Currently, scientists are predicting that there is about a 37 percent chance that a megathrust earthquake of 7.1+ magnitude in this fault zone will occur in the next 50 years. This event will be felt throughout the Pacific Northwest.

Small earthquake felt by some on Oregon coast

ROSE LODGE, Ore. - A 3.6-magnitude earthquake was felt by some Oregon coast residents Sunday morning, and unlike many such quakes, this one wasn't centered offshore but a bit inland.

The Oregonian/OregonLive.com reports that minor shaking was reported along the coast from Waldport to Cloverdale, with scattered reports further inland. No damage was reported.

Earthquake and aftershock rattle Oregon coast
AUGUST 22, 2018 / 8:51 AM / CBS/AP

An earthquake and aftershock struck overnight off the coast of south-central Oregon, CBS affiliate KOIN reports.

The United States Geological Survey reports the initial quake, with a preliminary magnitude of 6.2, occurred just after 1:30 a.m. local time. It was centered more than 170 miles (264 kilometers) west of Coos Bay, about 220 miles southwest of Portland.

Robert Sanders of the USGS says there is no tsunami threat associated with the quake. He says people as far away as Portland reported feeling the tremblor.

If it was felt in Portland, then it was felt along the Oregon Coast, all of which is closer to the epicenter than Portland.

ASTORIA, Ore. -- A 3.8 earthquake struck about ten miles west of Astoria about 7:52 a.m.

The quake was about 20 miles deep, according to the USGS.

Clatsop County emergency dispatchers said there were calls about the quake, but no reports of damage.

A safe generalization is to say anywhere around the Pacific Rim is susceptible to quakes: Alaska to Chile, and anywhere inbetween, and from Japan south to the Philippines!

Do you know where the Cascade Subduction Zone is located? Hint, no part of it is on the Oregon Coast. Do some more research and try again.

9.0 and above — Causes complete devastation and large-scale loss of life.
8.0 — Very few buildings stay up. Bridges fall down. Underground pipes burst. Railroad rails bend. Large rocks move. Smaller objects are tossed into the air. Some objects are swallowed up by the earth.
7.0 — It is hard to keep your balance. The ground cracks. Roads shake. Weak buildings fall down. Other buildings are badly damaged.
6.0 — Pictures can fall off walls. Furniture moves. In some buildings, walls may crack.
5.0 — If you are in a car, it may rock. Glasses and dishes may rattle. Windows may break.
4.0 — Buildings shake a little. It feels like a truck is passing by your house.
3.0 — You may notice this quake if you are sitting still, or upstairs in a house. A hanging object, like a model airplane, may swing.
2.0 — Trees sway. Small ponds ripple. Doors swing slowly. But you can't tell that an earthquake is to blame.
1.0 — Earthquakes this small happen below ground. You can't feel them.


Measuring Earthquakes _ Scholastic.com

There is no shaking under 4.0. Magnitude 3.X happen all the time. It's not something most people even notice.

It's Cascadia, and it appears you are the one who needs to do a bit of research.

The area where the subduction begins is off shore, but the Juan de Fuca plate is sliding under the N. America plate under the Oregon coast.

Did you read that article before you posted it?

The Cascadia Subduction Zone is a 600-mile fault that runs from northern California up to British Columbia and is about 70-100 miles off the Pacific coast shoreline.

It's a hundreds miles away from the coast and hasn't produced an earthquake in over 300 years.

About 15-20 years ago a 7.1 quake rattled Seattle, only big damage was the state capitol dome in Tacoma.
