Mount St. Helens Volcano Erupting

Mount St. Helens is spewing some ash this afternoon. Here is a live images from Johnston's Ridge observatory at Mount St. Helens. Other images and news from the volcano are posted below.

See, I'm interested in all things that explode. After all, volcanos are nature's nuclear bombs!

Here is a live image of Mount St. Helens. If you don't see anything it's either a) night b) erupting. In case of b please evacuate. Thank you.

I posted on this yesterday, but there is just something so cool about a know, erupting! Speed of Thought and I'm sure many others are volcano watching too.

The volcano seems to be less active this morning, but don't get too complaicent. This eruption came with no warning and with no sizeable earthquakes to warn us.


Mount St. Helens appears to be settling down this morning after a startling blast shot gritty volcanic ash to about 36-thousand feet above sea level.
CNN:Scientists want to peer inside the crater of Mount St. Helens on Wednesday to locate the origins of a plume of ash and steam that spewed nearly seven miles high into the air Tuesday night.

Geologists cautioned the explosion wasn't necessarily a harbinger of a larger or more destructive eruption.

The U.S. Geological Survey (USGS) in Vancouver began a 24-hour volcano watch after the eruption at 5:20 p.m. (8:20 p.m. ET). Nearly five hours later, the plume remained visible in satellite photos.

Glowing tendrils of lava were spotted inside the mountain's crater following the explosion. Although the plume rose nearly twice as high as one produced by the last eruption in October, the geological agency classified the event as "small," according to an advisory on the Web site of its Cascades Volcano Observatory.

No damage or injuries were reported. Some air traffic had to be routed around the plume as it rose to 36,000 feet.

Ten small earthquakes were measured in the area on Tuesday leading up to the eruption. The largest appeared to be a magnitude 2.5, according to the USGS.

After a relatively quiet night, a small jet of steam could be seen rising from the mountain on Wednesday.

The ash remained in the air over Montana and was visible for more than 50 miles (80 kilometers), prompting some motorists to stop their cars and watch. Falling ash was reported in towns up to 90 miles north and east of Mount St. Helens.
