Mount Saint Helens in review

Image courtesy of USGS/CVO, taken March 8, 2005 from the Cascades Volcano Observatory, Vancouver, WA For those of you looking for something to relax with and read this weekend, you could wander over to the USGS website and download yourself a copy (for free and legally) of “A Volcano Rekindled: the Renewed Eruption of Mount…

Back in a former life, I was really into radio and music. Such an existence calls for many lists of rankings: “Best albums of 2004″, “All time greatest soul singers”, “Worst album covers of the 1980s”. And, although I love a list as much as the next person, I tend to find lists appalling. Why?…

Redoubt seems to be setting its pattern for this part of the new eruptive period. There was another small explosion this morning that produced at 15,000 foot / 5,000 meter ash column that moved to the NNW. The seismicity has settled down since the early morning eruption today (3/25) as well. These types of explosions…

Redoubt update for 3/17/2009

Now that Redoubt has decided that Yellow/Advisory is not to its likely and has returned to an Orange/Watch status, I’ll continue bringing new updates of the volcano has events unfold. And nothing much has unfolded since the phreatic explosion that occurred on Sunday. The current state of the volcano, according to AVO, is minor seismic…

Redoubt in Alaska for the past two months like many of you have. For a time there, the volcano had the nation’s attention, both…

Volcano monitoring in the news

So, there has been a lot of talk about “volcano monitoring” over the last 24 hours, now hasn’t there? Now, I’m not going to revisit this discussion, but as an example of why it might be important, there is an article today about the location of the Bataan Nuclear Power Plant in the Philippines (near…

More signs of melting at Redoubt

The “eruption watch” continues at Redoubt … Saturday revealed that things are getting hotter at the summit near the 1989/1990 dome (see picture above that made Redoubt famous in 1989). The overflight of the volcano revealed new holes in the summit glacial and a multitude of muddy streams formed from the meltwater. This area of…

The Holiday Pause

Well, the holidays (and its visitors) have derailed my blogging ability, so in that note, I will officially declare the Eruptions holiday until 12/30. Merry Christmas (or whatever you celebrate) to all the Eruptions readers – and I just hit the 100,000 visit mark, a great Christmas gift for me! – and I’ll catch up with…

All quiet on the Cascade front

The only volcanic arc in the lower 48 states continues to be pretty darn quiet according to the USGS. The Cascade range that spans from Lassen Peak in the south to Mt. Baker in the north (and maybe Mt. Garibaldi in Canada) has been remarkably quiet in terms of eruptions for the last century. In fact,…

Mt. Saint Helens trivia

It is always fun to try to comprehend the sorts of numbers that geological processes produce. I mean, how much is 125 million cubic yard exactly? Well, the Cascades Volcano Observatory puts it this way: “From October 2004 to late January 2008, about 125 million cubic yards of lava had erupted onto the crater floor…
