The latest USGS/Smithsonian volcano report, with news of volcanic eruptions around the world.

Ash isn't just a respiratory hazard – it can actually disrupt the power grid as well.

The mystery surrounding Karkar's supposed eruption continues to grow as this week's GVP Weekly Volcano Report adds some details.

I've gotten a lot of great reader photos for the Mystery Volcano Photo competition … and now I'll start posting them. Have a guess at this one!

Google Streetview now lets you visit Pompeii, farmers in Hawai`i are eligible for disaster money for vog damage and National Geographic joins the SB fun.

The competition is getting fierce in the Mystery Volcano Photo competition. Take your best guess at #18.

A holiday Mystery Volcano Photo for you all to enjoy.

Volcanoes don't take vacations, and Karkar in New Guinea is keeping me on my toes even in the holiday week – it might have just had an impressive eruption.

The "significant" eruption at Karkar reported last week turns out to be a significant phantom – how did the Darwin VAAC get such a large "false positive" for an eruption?

Catching up with some of the past week's news, including new evacuations in Vanuatu, some new research on the destructive force of the Toba eruption and images of Bezymianny from space.

Well, I've now found myself with a volcano image I can even identify … but its a stunner.

Lots of huffing-and-puffing from volcanoes around the world, all wrapped up neatly in this week's USGS/SI Volcano Activity Report.

Got any suggestions for Eruptions? Let me know!

Eruptions at Galeras in Colombia have prompted evacuations and road closures. Meanwhile, the ash from Huila is likely helping coffee growers and the scientists drilling into Campi Flegrei in Italy don't want it to erupt either.

Just a note to all my readers: I’ve discovered today that Gmail has been eating (sending to the Spam folder) a significant amount of emails I’ve received to eruptionsblog gmail.com. […]

Take a whack at Mystery Volcano Photo #13!

So MVP #13 was apparently way too easy, so here's a bit more a challenge (I hope).

I'll try to stump readers again with a new Mystery Volcano Photo during this slow week in the world of eruptions.
