The eruption plume from Tungurahua on December 16, 2012. Image via @Tavi53 Quick update for today - only 4 shopping days until Maya Apocalypse! Ecuador We've seen a couple spectacular images of explosions from Ecuador's currently noisiest volcano, Tungurahua. This rejuvenated activity in December has promoted evacuations of people living near the volcano as both ash fall and pyroclastic flows are a very real hazard. The plume reached as high as 3 km / 16,500 feet over the weekend and seismicity remains high -- all of which has the volcano on Orange Alert by the national civil defence agency of Ecuador. Indonesia Across the globe in Indonesia, Lokon has also been keeping active with numerous explosions, like this one from earlier today. That same brief Reuters report claims that Lokon has experienced over 800 explosions over the last 6 months, an impressive number to say the least. The plumes from the explosions are reaching 3-4 km / 11-14,000 feet. Lokon is joined by Paluweh in this week's Global Volcanism Program Weekly Volcanic Activity Report and another 6 volcanoes are on Orange Alert status according to PVMBG. Russia
The eruption of Tolbachik is still ongoing as this recent Terra image shows. Even with its remote location on the Kamchatka Peninsula, the eruption is drawing tourists - and I suppose it isn't a shock considering how impressive the lava flows are (see below -- be sure to check out all the images in the KVERT gallery). Some people are also trying to connect this fairly small eruption to my favorite, the Maya Apocalypse, claiming a sign of the end will be eruptions. Of course, as we all know, eruptions occur all the time, so why is this eruption in one of the most volcanically-active places on the planet a harbinger of doom? It isn't. The latest GVP Report has the lava flows stretching 17-20 km from the vent, quite the distance for any lava flow, and the alert level remains at Orange.

In Focus in the Atlantic has a great image collection of volcanic activity from 2012.
The ocean entry continues in Hawaii from Kilauea, but the lava flow is now only intermittently entering the ocean, producing small steam clouds. Both the summit area and Pu'u O'o are showing deflation right now.
Finally, thanks to Oxford Sparks, a cartoon about subduction-related volcanism that actually gets it right (although I think the tourists should know better at the end of the cartoon).
