50 earthquakes hit off the Oregon coast, but scientists say they're no great shakes

A swarm of earthquakes led some people to worry that the seismic activity might portend The Big One. But seismologists say that given the location of the quakes, there was no cause for alarm.

Did anyone feel any?

We didn't and we live in Speederfundus south of Bandon by the sea. Bride tells me they are calling this group of earthquakes the Blanco bundle.

Is this stress release, or a sign of the BIG ONE?

No, I did not feel anything.

I saw an article on this and they cited a scientist that shrugged it off, saying this wasn't unusual at all. And based on the type of quake they were, tsunamis were not a threat.

No, I did not feel anything.

That's what she said...

...

...wait a second! She didn't say that at all. She said something completely different!

Swarms happen all the time out in the ocean and on land in the PNW. Swarms and mild shakes usually get a short mention in the news if at all.


I have experienced 4 quakes since the 80s. The Nisquly quake shook enough for us to evacuate and that was hundreds of miles from the epicenter.

In one my car started swaying back and forth, in another I was on a boat and it started rocking.

I was living in Portland during St Helens. A quake felt in Portland sounded like bowling balls rolling on the floor above me.


The Cascadia fault is the killer. Coastal towns have early warning systems and some built platforms to escape tsunami flooding.

For a local quake 5 is a pretty good shake up. 3 is felt and can knock some things around in the house.

The USGS has online real time reporting of quakes.
