Seismic activity at Mount St. Helens has changed significantly during the past 24 hours and the changes make us believe that there is an increased likelihood of a hazardous event, which warrants release of this Notice of Volcanic Unrest. The swarm of very small, shallow earthquakes (less than Magnitude 1) that began on the morning of 23 September peaked about mid-day on 24 September and slowly declined through yesterday morning. However, since then the character of the swarm has changed to include more than ten larger earthquakes (Magnitude 2-2.8), the most in a 24-hr period since the eruption of October 1986. In addition, some of the earthquakes are of a type that suggests the involvement of pressurized fluids (water and steam) or perhaps magma. The events are still occurring at shallow depths (less than one mile) below the lava dome that formed in the crater between 1980 and 1986.

A couple in Olympia, even closer!
Hope everyone out there stays safe.
A micro earthquake occurred at 22:58:58 (UTC) 3:58PM local-my note on Sunday, September 26, 2004. The magnitude 2.0 event has been located in the MOUNT ST. HELENS AREA, WASHINGTON. (This is a computer-generated message -- this event has not yet been reviewed by a seismologist.)
That's us! :~D
Welcome.
The quakes are cause by magam moving up the pipe from the magma chamber.
If she does go, I'm hoping it's the itty bitty stuff like she did in ancient history that built up the previous nice pretty mountain.
But considering she did the explosive blast eruption, that pretty much says that the composition of the magma has changed.
I know... how ya doing?
I keep hoping to see Rainier go for the spectacle of it, but it's not active.... If it was, it would be much more damaging.
We're good! and you? We barely see Penny anymore. :~\
Yes, the ash mixed with the ice/snow in 1980 creating "lahar flows" down the Toutle River.
She's busy. We only see her once or twice a week.
Nice picture! :) Looks like Mordor had better weather that day than when they shot RotK, LOL!
Yes, we found Mordor to be a cheerful, sunny place full of new life ;~D
i'm sure / hope they are comparing the event duration and frequency to the last time it went boom...
Well, say Hullo to her for us!
Hmmm--sounds like you stumbled into the dream scene from the Bakshi RotK where Sam imagines turning Mordor into a garden--thankfully omitted from the Jackson version :)
Hi...Darksheare,
Thanks for the PING, I'm on the East Coast and getting ready for Tropical Storm/Depression JEANNE.
PRAYING for Everyone on the WEST COAST.
May The Living GOD of Abraham, Isaac and Jacob (Israel) BLESS AND PROTECT ALL OF YOU and KEEP YOU IN HIS CARE.
We are getting closer and closer to The BIRTH PAINS...
READ: Matthew Chapter 24, focus on verses 7 & 8!
Keep safe down there, ya-all. Ping?
