A few reports this morning that Mt. Soputan, on the island of Sulawesi in Indonesia, is currently erupting. The reports indicate that there has been a lot of seismic activity […]

nn I had been looking for some pictures of the recent eruption of Cerro Azul in the Galapagos, and finally I found some posted on the BBC. There are some […]

Today, I saw a report that a dome on Arenal in Costa Rica had collapsed last Friday (report in Spanish, but good picture of the event), producing a block & […]

nn One of the most famous eruptions in human history (at least recent history) is the 1883 eruption of Krakatau in Indonesia, made (more) famous by Simon Winchester’s book (and […]

nn I mention this little human interest piece mostly because I am especially found of Mt. Tarawera (note: this link goes to the GVP page for Okataina, the volcanic cluster […]

nn Most people don’t realize that a majority of the earth’s volcanoes are underwater. That is to say, the mid-ocean ridge system that runs along the bottom of all the […]

nn Authorities in New Zealand have issued an alert for White Island. After a fairly sizable earthquake (M=5.4) near the island, the state agency that oversees volcanoes (GNS Science) is […]

So, this was a bit of a surprise to me. Six weeks into the Chaiten eruption in Chile, apparently the volcano has picked up the tempo again. Not much in […]

nn Just a quick update for today (busy watching Red Sox vs. Reds, sorry, that is my other love: baseball). New reports concerning White Island suggest that an eruption is […]

nn The newest reports out of Chile are indicating that the eruption at Chaiten has reached levels of intensity not seen since the eruption first started over six weeks ago. […]

I am always amazed by the number of volcanoes that show signs of activity every year that I have never heard of before. Case in point is this report of […]

Over the weekend, Mt. Etna (Italy) had some spectacular Strombolian fire-fountaining. Lucky for us, Marco Fulle and a group went up to the summit on Friday (the 13th) and got […]

nn The western Pacific basin is pockmarked with active and extinct volcanoes related to the subduction of the Pacific plate along almost all of its western boundary. An Australian National […]

nn Just when you thought it was safe to go outside. nn After apparently settling down a bit over the weekend, Chaiten has kicked it back up a notch. The […]

nn If Alaska wants to take a cue from Iceland, it might find itself with more power than it can use. That is, if the dreams of the Alaska Division […]

nn Not much in the way of science to add here, but photographers at Hawai’i Volcanoes National Park are still busy around the clock documenting the summit vent activity at […]

Things have quieted down on the volcano-news front lately. I did catch a report that Fuego (Guatemala) is having small explosions (stombolian eruptions; link in Spanish), producing small (100s m-tall) […]

nn Since the “surprise” eruption of Chaiten in southern Chile (still erupting away), I’m sure there has been a lot of talk about better monitoring and predictions for volcanic eruptions. […]

nn Almost 9 months since its last eruption, Ruapehu is keeping New Zealanders guessing about its next move. Brad Scott of GNS Science (NZ) reports that the crater lake at […]

I found this picture on the SF Chronicle website and it speaks volumes about the destruction wreaked on Chaiten, Chile. The ash has buried the town and what the ash […]

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 […]

I think we know who wins this battle. At Ruapehu (New Zealand), it isn’t really the lava that is the problem, but the lahars produced by mixing snow, crater lake […]

nn Tungurahua, one of the most active (and harder to pronounce) volcanoes in the Andes, has been experiencing explosions over the last few days. Not much in the report beyond […]

People living around Semeru Volcano, Indonesia, have been put on alert for a potential eruption. Indonesia’s Centre for Volcanology and Geological Hazard Mitigation has put the volcano on level 3 […]

Looks like a lot of you have found my (fairly new) Eruptions blog via the kind post over on another excellent volcano blog, the aptly titled Volcanism Blog. That blog […]

I’m always amazed by the number of volcanic eruptions captured by satellites that we might not have ever even had known occurred otherwise. Case in point is Rabaul on the […]

Although the mainstream media seems to have lost interest in the Chaiten eruption beyond the “human interest” (or should I say “salmon interest”) aspect of the eruption, there is still […]

nn If you’re interested in the latest eruption at Mt. Etna (Italy), here are some great images posted at Stromboli Online. Nothing like some good spatter amongst friends.

Some news from the Chaiten eruption. Apparently, LanChile has cancelled some flights around the region of southern Chile due to the ash. They likely implies that the eruption column is […]

The Oregonian reports on the on-going desire to develop geothermal power in the Oregon and California Cascades and backarc. There have been attempted (or at least exploration) to develop geothermal […]
