SUMMARY

Mount St. Helens is experiencing a significant increase in seismic activity, with scientists estimating a 70% chance of a small eruption occurring within days. Recent observations indicate that the 1,000-foot lava dome has shifted 2 inches, and continuous Richter 3 earthquakes are ongoing. A level 3 alert has been issued, indicating imminent danger to life and property, with experts predicting a potential eruption magnitude of 3 on a scale of 0-5. The situation is evolving rapidly, with increased volcanic tremors and steam releases detected.

PREREQUISITES
  • Understanding of volcanic activity and eruption scales
  • Familiarity with seismic monitoring techniques
  • Knowledge of volcanic gas emissions and their implications
  • Awareness of evacuation protocols in volcanic regions
NEXT STEPS
  • Research the USGS monitoring systems for volcanic activity
  • Study the geological history of Mount St. Helens and its past eruptions
  • Learn about volcanic gas detection methods and their significance
  • Investigate emergency preparedness plans for communities near active volcanoes
USEFUL FOR

This discussion is beneficial for volcanologists, emergency management professionals, residents near Mount St. Helens, and anyone interested in geological hazards and volcanic monitoring.

MOUNT ST. HELENS, Wash. - The flurry of earthquakes at Mount St. Helens intensified further Thursday, and one scientist put the chance of a small eruption happening in the next few days at 70 percent.

Interesting.
 
Earth sciences news on Phys.org
I've been hearing this, but the description I heard suggested it wasn't going to be a big, big one.

Has anyone heard any good specifics?

A little more than just "interesting" to those of us who live near the mountain.
I hear that the information center, which is 5 mi (~ 8km) from the crater is the busiest that it has been in years.

Hummm... Let me think about this...

She's going to blow! Let's go stand in front of it!

Me, I live a comfortable 200mi away, I think I'll watch it on TV!

Edit:From what I saw last night, the 1000' lava dome in the crater has moved 2" (5cm) in the last day or so, there is a nearly continuous Richter 3 earthquake underway. Yeah, they say it is going to be small... What is small, when it comes to volcanic eruptions?

That's what I've heard also. That it won't be near as violent as before.
 
It erupted earlier this morning, a pretty good spew of steam an ash, heading to the south west, perhaps we will get some here.
 
Just 55 miles away from the mountain myself and it is a bit exciting, but not devastating like the 1980 eruption.

No kidding. And many volcanologists have either been killed or had very close calls. I listened to one guy describe his experience in which about six other scientists died. It was like something out of your worst nightmare.

Nothing very violent, I'm sure.

Just a quick update. The Earthquakes, which had subsided after the burst, picked up again earlier this evening.

as of saturday p.m.-more earthquakes and evacuations for thousands! amazing...interesting to be a part of this!

Apparently after the second small eruption today of ash and gasses, the tremors intensified, so they're thinking it's going to be much bigger than just these burps.

Where are the closest homes in relation to the mountain? I would think after the 1980 eruption that people would not want to live quite so close to an active volcano.

Today scientists detected volcanic tremors which indicate the flow of lava underneath the dome. There was a steam release and Hydrogen sulfide gas was detected [by nose]. A level 3 alert was issued - the highest level - which indicates that not only is an eruption is imminent, danger to life and property also exists. When asked how large of an eruption we may see, experts indicated that on a scale of 0-5, with the eruption yesterday being a 0, and the one in 1980 being a 5, we may see a 3; potentially greater. So this is getting quite serious.

hmm
does anyone know where we can see the first blast on video?

Do you mean from 1980?

Plenty of info available...

I meant from the recent one but 1980 would be nice also

It looks like you may have missed my last post. They have a nice page set up for this.

getting serious yes, and interesting...the closest town to st helens is 30 miles away...the biggest problem i think that is a threat is the ashfall...

I remember the news footage from 1980, seeing ash covering everything the way snow would. Volcanoes seemed even more exciting when I was a kid than they do now, but then I think everything did...the world seemed so much more dramatic even though it's really the same (or maybe it was the way they showed the news).
 
  • #21
what is interesting is, when the public was evacuated from the observatory just 4 miles away, they acted like they were being inconvieneced because they had to leave (according to the what i saw on the news)...i guess some people have no clue how powerful nature is...

apparently it is just mostly steam due to the glacier coming in contact with a mass of magma...this isn't the big one yet...

I wish I were there. I'd probably be one of the tourists who wouldn't leave voluntarily. Damn my scientific curiosity!

And I was just going to make a comment about Darwin award candiates!

Then let's not mention the thing I did that time with the garden hose... (just kidding)[/size] In all honesty, I would find it difficult to pull myself away, but would probably wet myself and flee once I saw an indication that the situation was more dire than just a USGS warning or a plume of steam.

It's a good thing I'm not a volcanologist...

the lates-st helens is gearing up for a real explosion...all of these puffs of ash and steam are most just cracks in the crater opening up and the glacier inside the crater is coming in contact with the hot inside. it truly is exciting to be witnessing this...

USGS: We should see magma soon.
 
  • #30
I just heard that it was quieting down from my geology professor. Who knows what's going to happen.
