Eruptions

Archives for October, 2008

After nearly a year and a half of little lava dome growth at Soufriere Hills in the West Indies, this past July 26th, the volcano erupted new dome material. Why do I remind us of this, you ask? Well, the Scientific Advisory Committee at Montserrat feel that the dome growth might be restarting in earnest:…

Volcano Profile: Rabaul

Sorry about the dearth of posts. It has been a busy week here in Davis and I’ve been a little distracted by the upcoming election. Combined with the relative lack of volcano news this week, the posting has been lackluster. However, that being said, I will try to make up for some of it by starting my…

The headline for this entry sounds more dramatic than it is, but one of the last structures in the ill-fated Royal Gardens subdivision on the big island of Hawai’i finally met its fiery demise over the weekend. For those of you unfamiliar with the plight of the subdivision, Royal Gardens is part of Kalapana, and…

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,…

Klyuchevskoy’s new eruption

Reports from Russia indicate that Klyuchevskoy, Russia’s largest volcano, is erupting. It sounds like it might not be just a murmur as Alexei Ozerov from the Institute of Volcanology and Seismology of the Far Eastern branch of the Russian Academy of Sciences says the volcano is spewing ash, rock and gases. No real details on how tall the…

There isn’t really much information in this report, but Galeras in Colombia has been put on “high alert” for a potential eruption. The volcano did emit a ~2,400 meter steam (and ash?) column today, but beyond this, it is unclear what else might be happening at the volcano. Galeras is the most active volcano in…

Kasatochi now an island of ash

The eruption of Kasatochi was a bit of a surprise to volcanologists who study the Aleutians, to say the least. The volcano itself has been quiet for likely over 100 years, but with relatively little warning, the volcano erupted over the summer, blasting ash (and a large amount of sulfur dioxide) into the atmosphere. We…

Ash eruption video from Halemaumau

On Sunday afternoon, a large ash eruption occurred at Halemaumau Caldera at Kilauea. Not only did the volcano belch more grey ash than usual, but also red-hot incandescent material can be clearly seen being thrown from the vent during the vigorous eruption. The coolest thing about the eruption is that it was all caught on…

New posts soon!

      I’m a little behind on the news after spending the weekend field tripping at Lassen Peak. I’ll be catching up soon, but to tide you over, here is a picture I took of some bubbling mudpots/springs at Bumpass Hell near Lassen Peak. The dark areas are pyrite crystals floating on the stew!

A magma chamber’s ebb and flow

If you ever want your research to be picked up by the popular press, you pretty much need to publish in the journal Science. It (along with Nature) are seen as the Premier League of scientific publication, and even though there isn’t a lot of agreement on whether what gets published in these journals is…
