Well, it might seem early for some of you (and wrong for those of you in the southern hemisphere), but summer is upon us. Classes are 100% done here and I’ve spent the last week slowly changing gears from teaching ...

The high alert at Mexico's Popocatépetl remains in place as the restless Mexican volcano still shows signs that new magma is at the surface, meaning a larger explosion could occur if pressure builds under the summit crater.

The eruption that started on Monday at Pavlof in Alaska continues unabated. The Alaska Volcano Observatory is reporting a dark steam-and-ash plume reaching ~6 km (20,000 foot) and drifting to the southeast by pilots passing nearby and the glowing lava ...

Right now, 5 fewer volcanoes have any active volcano monitoring along the vast Aleutian arc. That might seem insignificant to many people — I mean, what harm do five volcanoes in the northern Pacific pose? — but really, it is ...

Earlier today, the Alaska Volcano Observatory raised the alert status at Pavlof, a stratovolcano near the western end of the Alaska Peninsula, to Orange/Watch. Increased seismicity combined with a strong thermal anomaly spotted by satellite at the summit of the ...

It has been a few months since anything much as happened at Chile’s Copahue. Last December, the volcano had a couple small explosive eruptions that sent ash across the Chilean border into Argentina, but that activity didn’t seem to be ...

I don’t have a lot of details right now, but it seems that an explosive eruption has started at Popocatépetl outside of Mexico City. The restless Mexican volcano has been producing steam-and-ash plumes intermittently over the past year, but tonight ...

Yesterday, a small explosion on the Philippine volcano Mayon killed five climbers. No volcano is ever truly "safe," says Wired Science blogger Erik Klemetti, who offers some tips on how to reduce risk while hiking or climbing on volcanoes.

After a sequence of explosive eruptions, the Alaska Volcano Observatory raised the aviation alert status at Cleveland to Orange. But there has been no visual confirmation yet, so how did we know there was an eruption (or several, in this ...

If you can believe it, today is the fifth birthday for this blog. Eruptions started on May 1, 2008 after I struggled to find useful and geologically-accurate information about the eruption that had just started at Chaitén in Chile (more ...

One of the best things about all the satellites that snap pictures of the multitude of volcanoes on the planet is their ability to capture ephemeral moments that are lost without these observations. Just today, I saw two sets of ...

I think it is time to catch up with some of the rumblings going on in Chile. There aren’t any actively erupting volcanoes right now (well, at least not in all certainty — Chile’s volcanoes can be very remote), but a ...
