Hundreds of earthquakes hit Mount Rainier — here's what's happening

Mount Rainier is experiencing its largest earthquake swarm since 2009. Is eruption next?

Mount Rainier, Washington's iconic snow-capped giant, has been experiencing quite the underground buzz: Starting in the early morning hours of July 8, 2025, the volcano has been rattling with hundreds of tiny earthquakes in what scientists call an "earthquake swarm" — and it's the most significant seismic activity the mountain has seen since 2009.

---------------------------

Well, it IS a freeking VOLCANO!!! Like DUH!!!!

These "swarms" are Mother Natures little nudges telling you to GET THE F**K OUTTA THERE!!!!

It's something we live with here. The swarms happen now & then. They are all less than 2.3 on the Richter, which happened sometime this morning. Not really a cause for concern.......YET.

I've been keeping my eye on this since yesterday. When I checked the USGS earthquake map site and changed settings to include all magnitudes for the last 30 days.........it showed activity actually started June 15 with a very small less than a 1. quake and a few (one or two) other similar quakes every day or two........up until about June 26 or 27 when they started picking up in number, but not really in size. It happens.

But I had also noticed there has been similar activity at St Helens, then scrolling out on the map....there has been quite the activity going on from the Rockies to the Pacific and all in between. The West is rocking and a rolling.


Having experienced St Helens eruption, though not in the direct path of it, it would take ALOT more than just a couple of days of quake swarms before it's panic time. The biggest differences would be that Rainier is much bigger than St Helens with a whole lot more power for destruction, since there are millions of people in it's path.

Scientists are most worried about lahars, debris filled rivers from melting glacier ice and anything in it's path from mountain to the sea and since the most and biggest rivers flowing from the mountain go right thru very populated valleys it could impact the South end of the Puget Sound and shipping ports, not to mention roads and Interstates.

Then of course any possible pyroclastic damage on top of the normal steam and ash.

PRECURSOR warnings before THE warnings.

I wouldn't really care about the seizmic activity.........I'd be more inclined to see what the wildlife is doing.
They are the TRUE measurements of what Mother Natures intents are.

Well, so far it's been about an hour and a half since the last one.....so maybe things will settle down. We'll see how it goes in the next few days

Mount Saint Helens redux.

No evidence of that yet. There is a type of earthquake, a volcanic tremor, that indicates magma moving. If we see that signature then there is reason to worry. And, as Rainer is one of the most monitored volcanos in the world, the geologists will give us plenty of warning. That is, if someone in this admin does not defund all the monitoring.

Geologists wouldn't have to give warning as the mountain would give plenty of warning of it's own. I am by no means an expert or geologist, but as far as I can tell, every mountain around the world that has erupted, has blown steam & ash along with changes in the landscape around it, like 'domes'(?) months in advance of actual eruption. So no reason to think Rainier would be any different.

The biggest problem I can see with Rainier is over a million people trying to evacuate. We only have 4 east/west mountain passes....North Cascades, Stevens, Snoqualmie and White. There are a few others, but small and closed often. Plus there is a hwy that goes along the Columbia River, Then there's I-5, north/south. 6 roads, that's it!! If anything happens late summer, North Cascades will be closed as it does every year, and White Pass is way too close to Rainier and would be closed as well. Stevens and Snoqualmie may or may not but Stevens is (or was a few years ago) only a 2 lane road, one in each direction. Snoqualmie is 3 or 4 lanes and both COULD help the congestion if both directions were opened for east bound traffic........as long as weather permits. If not, then everyone is on I-5 and maybe the road at the river.

Since most people wouldn't know the difference between a regular earthquake and a volcanic tremor......given the complexities, would geologists even bother to give warnings or evacuate?

 

[Failzero]

Ok I’m spooked , hope Mount Lassen does not awaken again ( Or Shasta )

 

[JustAnotherNut]

As of this morning, there have only been 5 earthquakes since last night with the largest being a 1.7 so things are definitely slowing down. So it's nothing to worry about and everything should go back to normal.

About the mountain passes, you overlooked mention of Chinook. Not quite as close to Rainier as White, but is next closest. Chinook links Enumclaw to Yakima.

Living in the area for the past 70+ years I wouldn't panic yet. As mentioned, lahars can be a more likely danger threat, but as we move further into Summer, more of the snow is melting of the mountains, including Rainier. Rainier would have to get very hot for lahars to happen.

I didn't mention it by name, but was included in 'the smaller passes'. Chinook as well as Cayuse.....I would think would be closed just because they run too close to the mountain. Even if they weren't closed, I sure wouldn't chance it.......and that's if any eruption happened in the summer. They definitely would be closed in the winter, as they usually are.


Living anywhere in a valley and/or near a river of any size could be dangerous. I live on a hill over 500ft above any valley or river and would probably be safe from direct impact, but could very well be isolated if roads & hwys are taken out.


My mind keeps repeating the scenes from St Helens, the rivers carrying houses, cars, trees, etc that nearly wiped out the bridge. And Rainier would be much worse. I'll see if I can find the video

Nevermind, I'm not about to watch thousands of videos to find the one I'm thinking of........but I'm sure you've probably seen it yourself. Of people and cameraman standing on the trestle bridge over the Toutle, watching as the river rises, with mud, trees, debris and the house that slams into the bridge


This video doesn't capture that much, but is closest that I can find at the moment........and I'm pretty sure that's the same bridge

Cayuse and Chinook passes with just two-lane roads but it has the best views of any passes in the state.

True.....but not a place I'd want to be if it erupted

If I remember my Geology most of the mud flows tends to move West.

I will have to consult my old Cascadia Geology Book I had for my Geology class in 1984 at Ellensburg.

Was Mount Lassen a footnote in that book ?

Yeah, I remember it quite clearly. I was living just East of Kent at the time and the road running due South to my home lined up with St. Helens.
Also recall a trip or two to Portland area shortly after when the damage was still fresh.

I first did CERT* training about 17-18 years ago and lahars are one of the more probable disasters for consideration in our training. I live close to Mt.Baker which done some 'grumbles' and steam venting in recent years and likely river channels for lahars could drop I-5 and other bridges essentially cutting off most of us North of Mt. Vernon from Southern connection. Access through British Columbia might prevail, assuming the Fraiser isn't also a channel.

* - CERT = Community Emergency Response Team
In my county, Whatcom, we operate under the Sheriff's Department Office for Emergency Management, and would also link in with FEMA.

Here is the fine book I own that covers it very well

Fire and Ice : The Cascade Volcanoes​

Amazon LINK

The Book covered all of the Volcanoes of Cascadia which starts in Southern Canada with Mt. Garibaldi to Lassen Peak which has its own chapter on it with a nice photo of the giant ash plume on May 22, 1915.

Also own these two books as well,

Agent of Chaos

Cataclysms on the Columbia: The Great Missoula Floods ​
