There's some earthquakes swarm at Mount Hood. Hard to know if the situation will turn like Mt. St.Helens or La Palma.

Mount Hood, Oregon's biggest volcano, is being rocked by a new swarm of earthquakes just months after a similar swarm struck the volcano.

In the previous 30 days, 41 earthquakes have hit Mount Hood's slopes and peaked; in the last 24 hours, 33 earthquakes have struck. The majority of the earthquakes have hit the southern flank of the stratovolcano in the previous 24 hours. The strongest of the earthquakes was a 2.5 that occurred earlier today.

Let's hope these quakes are not a sign Mt Hood wants to blow its top.

Things seem to have quieted down - for now?

That's good to hear. Isn't that how Mt St Helen's was in the period before eruption. Off and on small quakes for months or more before it blew? Seems like that's what I remember it was like in 1980 when that one erupted.

Actually, more often than not, seismic activity near a volcano does not mean the volcano is going to erupt. Volcanoes, including Mt Hood, are just part of the PacNW's bigger seismic picture.

Be glad you don't live here. Multiple tremors every hour some days. You learn very quickly to ignore anything smaller than Richter 4 but sensing that the earth under your feet (and your house) is moving around is still unnerving. Of Alaska's 40 active volcanoes most are located within the Aleutian Arc which I can see a couple of minutes' drive from the house. There are 4 large active volcanoes in plain view; Augustine, Iliamna, Redoubt, and Spurr. On a very clear day I can also spot a few smaller ones. If any of them decide to do something dramatic whatever they expel will get here in a few minutes.

Thanks for those links. Definitely a lot of activity. I spent 2 years in Alaska in the 70s. when I was in the Airforce. 1 year in Galena and the next year in Anchirage. I don't remember any quakes in Galena, but in Anchorage the ground seemed to move quite often. I've felt quakes in San Diego, Japan and in Portland. I lived in Oregon before I retired. I notice in each location quakes felt different. Some locations it felt like a shaking. In Alaska it felt like an up and down rolling motion. At least that's how they felt to me. Stay Safe.
