MOUNT ST. HELENS UPDATE

Current status is Volcano Advisory (Alert Level 2); aviation color code ORANGE: Growth of the new lava dome inside the crater of Mount St. Helens continues, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.

Anyone living close?

Please, be careful and check the news.
Love,

Thanks, Tessa

I hadn't visited the cam site lately. I hope it doesn't blow.

Love, Shirley

Yep, Tessa, I live pretty close to Mt. St. Helen's. Fortunately I live south. Most of the ash if it blows will end up east on Gaea's doorstep. Peg lives north of it and so does Momster and Jill. Lori and I live pretty close to each other.

I think it has been bubbling away like that for about a year. But who knows? I have been thinking about anything and everything that could be a danger. What about you?? Do you have any Spanish earthquakes or tornados on the horizon?

Thanks for thinking of us.

Lots of love,

Sally

Wow, thanks for the news...I am just now watching TV.....will watch the late news tonight.....I think the last fairly large eruption was when I was there with the kids last spring....no admage, but there was a good sized ash plume. I still have an ash mask in my car!

Thanks again...JJ

Hi again....I just looked it up.....this is the latest report...JJ

MOUNT ST. HELENS UPDATE

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that, early in the day, any ash clouds that rise above the crater rim could drift in any direction at low altitudes owing to light and variable winds. Any ash clouds that reach higher altitudes would drift southwestward. Later in the day any ash clouds would drift southward.

Potential ash hazards to aviation: Under current eruptive conditions, small, short-lived explosions may produce ash clouds that exceed 30,000 feet in altitude. Ash from such events can travel 100 miles or more downwind.

Recent observations: Seismic signals of rockfalls from the growing lava dome continue along with the typical background seismicity of one tiny earthquake every few minutes. The dome is largely obscured by clouds this morning, but clearing forecasts for the next few days should give us good views.

U.S. Geological Survey and the University of Washington continue to monitor the situation closely and will issue additional updates and changes in alert level as warranted.

Morning and I have been following this for awhile and it looks like the time is coming but the blow should not be nearly as bad as prior due to the difference in the type of build up.

When it blew last time the idiot I was married to was there working on a power plant and we visited 8 weeks later and the devastation was terrible.

Wauw, Sally!

I hope nothing happens and it is just some bubbling away as you mention.
I´ll keep you informed if I get more news about it.

Take care,
Love,
Tessa.

P.S.: We have no earthquakes where we live, thanks God

There were unusual events last week in Barcelona, with 12 tornados hitting the town, heavy rain, floodings, etc. and causing damage.

The main problem where I live is the lack of rain...

Hi Tessa,

Thanks for the update, I live in Vancouver, WA. I haven't seen anything in the paper or on the news, but I don't read the paper or watch the news very often. I will be sure to watch for news of it.

I have been gone most of the summer...I really appreciate you letting us know.

Love, KathyP

Hi....I have been watching the news for the past few days and to my knowledge there hasn't been one mention of the alert. I guess they figure we are used to the volcano by now...NOT! I sure would want to know about it if I lived on the Toutle River below Mt. St. Helens...they must have some sort of alert system in place. We have a lahar warning system in place for Mount Rainier. The towns in the Puyallup Valley, near Tacoma, are in a potentially dangerous location. There are signs everywhere for volcano evacuation routes which lead to higher ground. Thanks for the update....you probably know more than we do.....sigh.
Thanks...JJ

There was finally a news blurb on last night and this morning about two little puffs of steam and ash yesterday. There were also two earthquakes....what the volcano will do next is anyone's guess....TTFN....JJ
