The slow summer for volcanic eruptions continue. Only 11 updates in this week's USGS/SI report. Thanks again to SI's Sally Kuhn Sennert for compiling the news!

Highlights this week include (not including Kilauea) include:

  • Tungurahua in Ecuador produced some minor lahars on August 21 to go with steam-and-gas emissions.

  • Popocatépetl in Mexico produced an ash plume that reached ~8.2 km / 27,000 feet on August 20 and continued to produce steam-and-ash plumes throughout the week following.

  • Over on the Kamchatka Peninsula, both Koryaksky and Shiveluch produced significant ash plumes (reaching 3-5 km / 10,000-15,000 feet) and seismicity remained elevated at both volcanoes.

  • Chaiten, Chile, remains active over 18 months since it started erupting in May of 2008. Steam-and-ash plumes continue to be produced from Domo Nuevo 1 and 2.
