I knew that the minute I said I'd be back to a "regular" posting schedule that I would fail miserably, so maybe the less said, the better.

Thanks to all the readers who have been avidly discussing a number of fascinating topics over the weekend…

Even the SI/USGS Weekly Volcano Report seems a little light -- welcome to the dog days of summer!
Highlights from this week's report include:
"Thunderous sounds", incandescence and small plumes (hundreds of meters) with more frequent seismicity at Ibu in Indonesia.
A sharp increase in sulfur…

The game of insurance is everywhere in the news these days so it isn't too surprising to run across this brief article about the perils of getting insured if you…

Some more volcano news for the day ...
UPDATE 10:40AM Eastern: It has been pointed out to me that both of these articles are old. They apparently made it into my Google News feed thanks to a glitch in the magic interweb tubes somewhere. Just goes to show that blogging before coffee on a Monday…

Does anyone else feel like this has been a rather quiet summer, volcano-wise? Maybe I've been too preoccupied by my move to Ohio, but I feel like beyond a few relatively minor events (Shiveluch comes to mind), the volcano news has been pretty slow compared to the spring of this year. Go figure.
The…

In case you don't frequent the NASA Earth Observatory, I thought I'd call your attention to some images they recently posted that are, again, excellent shots of volcanism captured from space.
The current plume from Tavurvur Crater at Rabaul was shot by the MODIS imager on Terra in early August. The…

We've made it to Ohio! Tomorrow I'll hopefully be returning to regularly scheduled updates, but until then, enjoy this week's SI/USGS Weekly Volcano Report.
Highlights include:
KVERT mentions that seismicity has increased recently at both Kizimen and Kliuchevskoi on the Kamchatka Peninsula.
~4 km…

Time to vote for the next Volcano Profile. Feel free to leave any comments or suggestions after answering the poll!
What should be the next volcano for the "Volcano Profile" series?(surveys)
August 2, 2009
Quick hit post from beautiful Walnut, Iowa, but this was too interesting to pass up...
Bright plume spotted on Venus, image taken by the ESA Venus Express.
Did a volcanic eruption recently occur on Venus? No one really knows, but a bright plume of unknown material was spotted by an amateur…

If you have any questions about volcanoes, pictures of erupting (or not) volcanoes you'd like to share with me for Eruptions or have any general comments, please email me at
. I'd love to hear from you and maybe your question can make it into my next mailbag post (which should hopefully be coming…

The next up in my Volcano Profiles Series, is one of the most remote volcanoes on the planet, yet also one of the more closely studied and monitored (albeit from afar). Joining Vesuvius, Hood and Rabaul is Mt. Erebus, an active volcano on Ross Island in Antarctica and it definitely has some unique…
July 30, 2009
This is likely my last update until the end of next week sometime, so feel free to use it for any new volcano news you might see. Look for the Erebus Volcano Profile to be posted on Friday sometime, followed by the vote for the next Profile. Next time I post I'll be (back) in the eastern time zone…
July 27, 2009
Again, sorry about the paucity of posts. Getting prepared to move 3/4 of the way across a continent will do that. Look for the next Volcano Profile, this time for Erebus in Antarctica, to be posted sometime in the next week or so.
We did get some news over the weekend of a large eruption at…

Your volcano news!
Thanks, as always, to the USGS/SI Global Volcanism Program.
Highlights include:
The alert level at Sakurajima was raised from 2 to 3 by the Japanese Meteorological Agency. This was due to the increasing frequency of explosions at the volcano, some of which produced ash plumes up…

The servers and software behind the scenes here at ScienceBlogs will be getting upgraded tonight (7/21). After 7 PM (Eastern), commenting will be turned off (even though the comment form will still be visible). Hopefully things will be up and running by the morning, but if things seem squirrelly,…
July 20, 2009
Starting today and going until early August, you might see fewer posts on Eruptions than you're accustomed. This is because I'm in the process of moving to Ohio to get set up to start my new job as an assistant professor at Denison University. I'm excited about the move, but as you can imagine,…

Some of the articles you might have missed this week ...
A lava flow from Kilauea breaks local traffic laws in the Royal Gardens subdivision, Hawai'i
The Mayon Watch continues in the Philippines. No eruption yet, but some of the local newspapers are printing stories talking about "odd animal…

Shishaldin volcano in Alaska.
Yesterday I mentioned in the SI/USGS Weekly Report update that things appear to be afoot at Shishaldin in the Aleutians. Well, I checked the Shishaldin webicorder today and indeed, [SPECULATION] something seems suspect. Now, the increasing signal might be wholly…
July 15, 2009
Your weekly dose of volcanism from the USGS/Smithsonian Global Volcanism Program.
Highlights (not counting Mayon), include:
The activity at Mando Hararo in Ethiopia appears to be a fissure eruption. Ground observations saw a 4-5 kilometers / ~2.5-3 mile fissure with new predominantly 'a'a lava…

I frequent the Astronomy Picture of the Day website run by NASA on a daily basis. Yet somehow today I didn't check the site until well into the evening and was greeted by one of the best astronomy-…

Mayon erupting in August 2004.
The increasing unrest at Mayon in the Philippines has prompted National Disaster Coordinating Council (NDCC) to recommend the evacuation of over 75,000 people from around the volcano. This, however, will only happen if the activity at the volcano continues to increase…

I haven't done too many interviews in my day, so this was kind of fun. Wander on over to The Reef Tank and you can read my interview - mostly about the role of water in its many forms on Earth in understanding magmatism and volcanism. Thanks to Ava from The Reef Blog for the interview!
And if you…

Another fun weekend for me analyzing zircon on the SHRIMP-RG at Stanford University! I really know how to live it up during the summer.
Some news bits:

Hydrothermal fields are tricky beasts. They can wax and wane as the magmatic system heats and cools, as the water table rises and falls and as other events such as earthquakes or explosions might change the conduit systems. Changes are relatively common, as we've seen in recent events in the…

All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!
Highlights (not include Manda Hararo, Kilauea and Mayon) include
San Miguel in El Salvador has been experiencing increased seismicity. The last time the volcano erupted was in 2002.
A pilot spotted a ~10,000 foot / 3…

Two papers submitted, one to go. Keeps you quite busy, let me tell you.
Lava flow from a 2006 eruption on Mayon in the Philippines.
A few bits of news today:
A few more details about the ongoing watch of Mayon in the Philippines . There have been apparently no changes in the shape of the floor of…

A quick update on the rockfall in the Halema`uma`u (got it right this time!) Crater at Kilauea. Last week a rockfall blocked the vent that had been glowing for most of the year from the lava below, but the debris clogged the vent, producing minor accidental tephra explosion.
Lava in the recently "…

Sorry about the lack of posts - the holiday and "real life" had stepped in the way.
On with the news!
Mayon Volcano in the Philippines with Legazpi City in the foreground.
Mayon, one of the most active volcanoes in the Philippines, is causing concern due to increasing signs of activity. Renato…

There is a bit of a buzz today about significant rockfalls that occurred in Halema'uma'u Crater at Kilauea on June 30th. Some articles have suggested that the…

Three days ago, I received an email from Eruptions reader Gijs de Reijke who was curious about something he noticed in the daily OMI SO2 images:
OMI sulfur dioxide map over Ethiopia for June 30, 2009.
Now, I wasn't quite sure what to make of it other than the fact that there was an awful lot of…
