Quick note as I almost forgot to post last week's Smithsonian/USGS Global Volcanism Program's Weekly Volcanic Activity Report. Busy week all around for volcanoes - we've seen activity at Bromo, Merapi, Anak Krakatau, Bulusan, Kilauea and more ...

Some highlights include:

Semeru:

Another Indonesia volcano made some noise, with Semeru producing a ~4.3 km / 14,000 feet plume and the sulfur dioxide plume was detectable as far as 75 km SW from the volcano. Semeru joins its neighbor Bromo (Tengger Caldera) along with Rinjani, Merapi, Anak Kratakau and Batur in the Report.

Tungurahua: I haven't had a chance to mention much about the new eruptions at the Ecuadoran volcano, but Tungurahua has been producing a steady ash plume for the past few weeks. Over the last few days, the plume has been consistently over 7 km / 20,000 feet and the ash has been causing problems in Ecuador (spanish), especially around Guayaquil to the southwest (spanish).

Guatemala: Both Fuego and Santa Maria in Guatemala made the report as well, with small explosions typified by short (< 1 km) ash plumes and frequent incandescent blocks. Ash fall was noticed as far at 8 km from Fuego.
