Mount St Helens reappears from the clouds!

Just before sunset last night the weather cleared providing us with the first clear images of Mount St Helens for 11 days. The incandescent glow from the lavadome was visible throughout the night and there was one large rock-fall and associated outburst at 23:05. You can check out the images and movies on www.luscombe-carter.com!

Bad weather continues on Mount St Helens

It's been almost two weeks since we had a glimpse of Mount St Helens, especially at night. Multiple weather sysytems have moved through the mountains and there has been nothing but vague images of clouds on the nightly images. The weather forecast offers a small hope that we may see something either tonight or tomorrow night, but it then looks like clouds and rain for the next few nights. All I can say is, "come on summer come on!"

The fin takes a hit - Mount St Helens update

The large outburst from Mount St Helens on Saturday night was definetely caused by a section of the "fin" breaking away.

The images below were recorded by the USGS remote camera at the Sugar Bowl - the before and after shots clearly show a large section the rock structure had fallen. More images are available at the USGS/Cascades Volcano Observatory. (Click on the image to enlarge it and see the animation.)

A spectacular blast on Mount St Helens last night


It seems as if a large part of the large "spine" that was growing out of the lavadome collapsed last night in a spectacular blast of activity. Processed images from the Volcanocam (see above) clear show a large amount of bright (i.e. hot!) material being ejected from the area around the lavadome. I have just posted an animation of the event here.

The large tremor associated with the event can be clearly seen just after 22:50 in the webicorder trace below.

No glow , but a few bumps in the night...

Once again clouds obscured the view of Mount St Helen's crater during the night, although the weather is improving! So we should have better views over the next few days. There were several larger tremors last night, including a much larger one at 21:14, as shown in this webicorder trace from Yellow Rock (Yel - MSH). Here's hoping for some better night time views over the next week!

It's also worthwhile checking out the new views of the second large spine growing out of the lavadome in the crater. This feature will be the most likely source for outbursts during the night over the coming weeks. It's also the first such feature of the current eruption that is visible in the Volcanocam images.

Normal service has resumed....

I've been distracted by many different things over the last couple of months and haven't had time to update the blog. Hopefully, I now have a little more time to spare and normal service can resume... :-)

Mount St Helens has been relatively quiet over the last few weeks, with the notable exception of Thursday night, when multiple bright outbursts occured after midnight. Animations of the night's display is now posted on Mount St Helens at night.

You may notice that the website has been redisgned - that was last weekends effort. I hope it makes things a bit easier to navigate.
