Volcanic monitoring in Yemen

I’m always pleased to see more countries setting up volcanic monitoring networks. Well, I suppose I’m pleased when it is a volcanically-active country, I mean, Switzerland setting up one might be a little silly, but anyway. After last year’s eruption of Jebel At Tair in the Red Sea, we were reminded that there are potentially…

Ecuadorian volcano update

I have a few bits of news about one (of the three) volcanoes erupting in Ecuador. Reports from the Foreign and Commonwealth Office of Ecuador says the volcano is still erupting ash and there is evidence that lava is erupting from the summit vent. Not surprisingly, there is a travel ban on both Reventador and…

There haven’t been any major developments volcano-wise over the weekend, just a few updates on some current rumblings:   Soufriere Hills (Montserrat) coughed up more ash, producing ash columns to “thousands of feet” according to reports from the MVO. The eruptions/explosions were centered at the lava dome on the summit of the volcano, Seismicity has also increased,…

The Alaska Volcano Observatory is reporting that both current eruptions in the Aleutians – at Okmok Caldera and Mount Cleveland – are showing signs of a lava extruding from the vent. Thermal anomalies have been imaged at the vents of both volcanoes, although no lava has been seen thus far. Both volcanoes continues to emit…

The latest eruption at Llaima is beginning to slow down according to Chilean state geologist, Hugo Moreno. The volcano has been erupting for most of the month, forcing limited evacuations. The eruption has (so far) produced lava flows, ash falls and some bombs thrown from the crater. However, the SERNAGEOMIN is keeping the “red alert”…

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…

Kilauea’s new fire fountain

  Kilauea is busy keeping geologists and tourists alike wondering what the volcano will be doing next. The current report on the volcano tells of a new fire fountain at the Thanksgiving Eve Break-out “rootless cone”, about 6 miles from the ocean. The fire fountain started on Sunday night, issuing lava up to 40 feet in…

There are some nice videos of the current eruption of Kilauea (after some tedious commercials via the link at the top of the article) with lava spattering and lava reaching the sea on the 4th of July. Not much description of the eruption in the article, but it sounds like it is just the Hawai’ian…

The current eruption at Llaima in Chile is causing some concern about flooding in the Rio Calbuco near the volcano. The lava flows are melting snow on the volcano and this is being exacerbated by heavy rain in the area as well. The eruption seems to have waned some according to the governor of the…

Update 7/2/08: Sounds like the lava flows from Llaima are increasing … or that there are more of them. The lava flows, as mentioned below, pose a threat to melt the ice on the volcano and produce lahars, or at least flooding. Lots of news this morning about a new eruption at Llaima in Chile.…
