A bit of news for your last Monday in September:
Pumice deposits from the ~13,000 year old Laacher See eruption. Image by Erik Klemetti, taken in August 2007.
More press for Dr. Joyce and his campaign to make the people of Australia terrified that volcanoes will destroy them. He warns of "new…

OK, I admit it, this was a tough one. The MVP photo wasn't entirely distinctive, but the basaltic rift volcano of Ardoukôba in this small African nation was the answer. Nice job, Anne, for narrowing down the possible locations and nailing it.
MVP Standings (as of 9/25/2009)

So far, Eruptions readers have nailed every one of the Mystery Volcano Photos posted, usually within the first two guess. That leaves our standings as:
volcanista - 1
Elizabeth - 1
Ralph - 1
Cam - 1
The field - 0
Here's a MVP for you to identify. Good luck!

I missed the weekly report last week (sorry), but here is the new USGS/SI volcano activity report.
Highlights include:
Shiveluch in Kamchatka is still erupting away, producing ~7 km / 20,000 foot ash columns as the lava dome grows. There has also been pyroclastic flows spotted emanating from the…

Some brief tidbits for your Wednesday:
The view of Mt. Saint Helens from the Johnston Ridge Observatory.
There is a decent article about research being done at a dissected caldera system in the Italian Alps' Sesia Valley. The caldera in question is the Permian in age (248-298 million years old) so…

The Atherton Tablelands in Far North Queensland, Australia.
Nothing makes me shudder like any article titled "Blankety-blank volcano is overdue". Typically the article that follows is full of nothing but vapid speculation and media fear-mongering. So, it wasn't too surprising that an article titled…

Eruptions reader Doug pointed out in a recent comment that the seismicity at Mt. Rainier in Washington has increased over the last month or so. Take a look for yourself:

Taking a closer look, over the last week…

Sarigan Island in the Marianas - your MVP #4.
I have to hand it to all of you, each time I've tried to make the Mystery Volcano Photo a challenge, you beat it with flying colors. The photo is, in fact, of Sarigan in the Mariana Islands (thanks to Dr. Ed Kohut for providing the photo). Eruptions…

I'll be off in the mountains of Virginia until Monday, so no updates for the rest of the week. I'll leave you all with a new Mystery Volcano Photo sent in by a friend (I don't want to give any clues away just yet) ... hopefully one that might be a bit more challenging. Enjoy the weekend!

Mayon in the Philippines, taken in 2007
There has been a lot of waiting over the summer to see if Mayon in the Philippines was going to begin a new eruption sequence. This morning, the volcano had its first "eruption" since August 2008, producing a very small (~700 m / 2000 foot) ash-and-gas column…

There are a couple article out today concerning volcanoes and the economy, one on the plus side, one on the minus side.
Volcano Buono in Italy near Naples.
First off, nothing like volcanism to get me stoked for buying stuff, eh? Actually, I have to admit, the Volcano Buono mall (yes, mall) in…

Monday is here again already ...
A pyroclastic flow from Soufriere Hills heading towards the ocean. Note the large volcaniclastic debris fan being formed by repeated flows. Dated March 2006.
The "Science Advisory Committee" at Montserrat in the West Indies suggests that the current eruption of…

Undated photo of Shiveluch volcano in Russia.
In case you haven't seen the report yet, Shiveluch in Kamchatka has gone, as they say, "non-linear". KVERT has raised the alert level at the volcano to "Red" with reports of many strong explosions and an ash plume of >32,800 feet / >10 km. This…

OK, well, apparently MVP #2 was waaay too easy because Elizabeth got it on the first try - it was indeed Villarrica in Chile - I'll post something on Villarrica later this weekend. Anyway, for the weekend, I'll leave you with this photo. Hopefully it won't be so easy ... but then again, you all…

The first Mystery Volcano Photo worked out so well, I thought I'd try a second one, this time culled from my personal collection. I'll try to figure out a way to post the scoreboard on the blog so you can keep track of your standing as MVP continues.
Take your best guess!
Enjoy the weekend.

To the updates!
Batu Tara volcano in Indonesia. The volcano is currently producing small ash plumes.
I was distracted enough by trying to figure out a way to teach about Miller Indices that I plum forgot to post this week's USGS/SI Weekly Volcanic Activity Report. It was a fairly quiet week so you…

The first Mystery Volcano Photo (MVP, for short) seem to go well and indeed, the volcano in question was Concepcion in Nicaragua. Congratulations to volcanista for nailing it on the first try. I'll have to keep a tally of the winners for each MVP to name a, well, MVP MVP. So far, the scoresheet…

I'm going to start a little feature on these slow volcano days ... Introducing the "Mystery Volcano Photo"! I'll post a picture of a volcano and feel free to take a whack at identifying the volcano. I'll follow up with information on the volcano ... right now you can play for community honor, but…

San Cristobal in Nicaragua
I don't have much in the way of details, but the Associated Press is reporting that San Cristobal in Nicaragua has erupted this evening. The volcano reportedly experienced an explosive eruption and that nearby villages (how nearby is unclear) have received ash fall from…

Lets get right to it!
"Manmade volcanoes": can they solve global warming?
It does indeed seem that something is happening beneath Kanlaon in the Philippines. PHIVOLCS reports that the volcano experienced 257 volcanic earthquakes from August 23 to September 1, well above the usually "background"…

Starting sometime later this fall, readers on ScienceBlogs will be able to register with SB to create user profiles, keep track of stories and all that good stuff that social networking has created. In an effort to make it something useful to the readers, the head honchos at SB have set up a poll…

The move is complete (finally) ... so maybe I can settle down a bit, right? Right?
The world's deadliest volcano?
Anyway, a few things I stumbled across this week:
Forbes Traveler.com has a list boldly titled "World's Deadliest Volcanoes", which more or less is a slideshow of nice volcano pictures…

First day of class! As you might imagine, I'm a little scattered (well, with classes and the fact that we bought a house over the weekend. You know, just that).
The Tavurvur Crater at Rabaul erupting in 1994.
News!
The Examiner.com (SF) has a slideshow and brief article on the current excavations…

Not much in volcano news, however a lot of earthquake news this morning.
Did anyone else notice that two M6+ earthquakes occurred last night within one minute of each other last night (eastern daylight time)? The first was in the Banda Sea near Indonesia at 01:51:19 UTC (M6.8), the next was in…

Koryaksky (Koryak) in Russia
Yesterday in the USGS/SI update, I mentioned the current eruption going on at Koryaksky (a.k.a. Koryak). Today, the NASA Earth Observatory has some images of the plume from the Russian volcano heading out to the east over the Peninsula. The plume itself looks fairly…

The slow summer for volcanic eruptions continue. Only 11 updates in this week's USGS/SI report. Thanks again to SI's Sally Kuhn Sennert for compiling the news!
Highlights this week include (not including Kilauea) include:
Tungurahua in Ecuador produced some minor lahars on August 21 to go with…

Some brief notes before I dive headlong into the exciting world of faculty orientation!
A small steam plume coming from Turrialba in Costa Rica. Photo taken in August 2007.
There are some preliminary reports of the state of wildlife (and everything) around Kasatochi Island in the Aleutians from the…

The summit crater at Kilauea in Hawai'i has had a busy summer and now that fall is around the corner (yikes!), there is a bit of new info on activity in the crater.
Halema`uma`u Crater emitting a steam plume in January, 2009.
First off, the NASA Earth Observatory released an image of the steaming…

I've gotten a number of questions about volcano books as of late, so I thought I'd write a little post detailing my favorite volcano-related tomes, mostly pitched towards people without a geology-background, but some technical books for those of you who want the gory details (and be sure, they can…

Busy today with scouting out some field location for the class I'll be teaching this fall. Here's this week's USGS/SI Weekly Volcano Report. The report is a little more eventful than last week's, so enjoy!
