Here's a stunning shot of the current eruption at Okmok Caldera in Alaska (brought to us by National Geographic).
Personally, I think the best part is the fact that this was shot by an Alaska Airlines pilot! Talk about "to the right of the plane..." fodder.

Sorry about the brevity of this update, but I'm exhausted.
From the Alaska Volcano Observatory (AVO):
At this time, based on AVO analysis of satellite data, ash is
continuing to erupt from a composite cinder and spatter cone called
Cone D in the eastern portion of the 6-mile wide caldera or crater…

Sorry about the delay with updates, I am actually at a meeting filled with volcanologists (of all things), so updates might be a little sporadic.
A lot of news today about Okmok erupting in the Aleutians. The Alaska Volcano Observatory had this to say:
The eruption at Okmok continues based on …

Okmok Caldera in Alaska's Aleutian Islands erupted today, sending an ash column to at least 30,000 feet. Very little news has been released about the eruption so far beyond this information about the eruption column and some bits about precursor seismicity. A number of flights to Unalaska Island…

Some news of a series of small eruptions at San Cristobal in Nicaragua. Ash from the small explosions drifted to a town near the volcano, however officials for Ineter in Nicaragua say that there is little chance of a large eruption.
San Cristobal is one of the seven active volcanoes in Nicaragua.…

Just a brief note that the USGS has officially pronounced the eruption that started in 2004 at Mt. Saint Helens over. They lowered the alert level to "normal" after months with little to no signs of activity. The new dome that grew in the crater formed by the 1980 eruption is 125 million cubic…

Llaima (Chile) is experiencing an increased tempo in its current eruption. The National Emergency Office in Chile is reporting that the eruption has begun to take a more explosive character, with pyroclastic material being shot hundreds of meters from the main vent. Although the officials have not…

Â
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,…

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…

Indonesia's Volcanology and Geological Disaster Mitigation Center of the Ministry of Energy and Mineral Resources (whew, that is a mouthful) has placed Anak Krakatau on high alert for increased activity. Tourists…

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…

There are some astounding new pictures of Chaiten in full eruption over at the Smithsonian Website. There pictures were released by the USGS/VDAP team and show a full eruption column coming from the new dome in the Chaiten caldera (see above and below). The dome itself looks giant, filling up a…

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. The…

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 Ruapehu is reading unusually warm temperatures and high gas emissions, well after geologists there would have expected after the…

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 hasn't damaged, the water and debris from the swelled river in the background have finished off. This is what volcanoes can do in the…

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. Now, we don't know the full extent of the facts, but usually an eruption of the magnitude of Chaiten (VEI 6, i.e…

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 of Oil and Gas come true. They are planning to lease land on Mt. Spurr and possibly Mt. Augustine for geothermal exploration. Both of these volcanoes are…

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) ash columns along with some throwing incandescent blocks 30-50 meters from the vent. Just the…

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 Kilauea that started in March. Most of the activity is steam escaping from the vent, but at night, the vent glows red, proving…

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 University research group recently discovered a pair of undersea volcanoes that would put any good mining…

Just when you thought it was safe to go outside.
After apparently settling down a bit over the weekend, Chaiten has kicked it back up a notch. The latest reports say that two ash columns are active ... and that is about all we get for more news. Not surprisingly, most of the damage around the…

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 some great pictures of the current (ongoing) eruption which have been posted on Stromboli Online. Sounds like the eruption…

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 activity near Mr. Kurikoma, on the island of Honshu in Japan. The last known eruptions at Kurikoma were back in 1950, and they seem to be water-…

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 have to admit, that isn't a good sign in terms of keeping the volcanic edifice in one piece. There have been frequent, small…

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 not imminent. Although there have been earthquakes nearby, whether or not they could directly lead to an eruption is unclear, but…
June 13, 2008
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 the report except that apparently two new vents/craters have opened, there is an increase in ash emission and seismic activity. What this might be…

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 warning people to stay away from White Island for the next 48-72 hours on fears it might erupt. Normally, just…

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 major oceans can be considered one big volcano. However, thanks to its location deep underwater, we have only had second- or third-…

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 the inappropriately named film Krakatoa: East of Java ... hint: look at a map). Since the cataclysm eruption, a new volcano…

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 & ash flow that left a 800-meter scar on the volcano's flank. No one was injured during the avalanche, but tourists were evacuated as a…
