Roundup of Global Volcanic Activity
Kliuchevskoi (Kamchatka): Mild activity (small explosions and light ash emissions) continues at the summit crater of the volcano from the Smithsonian / USGS Weekly Volcanic Activity Report 18-24 March 2015:
Medvezhia (Kurile Islands, Russia): Satellite images showed a weak thermal anomaly over Kudryavy, a stratovolcano of the Medvezhia volcanic complex, on 18 March.
Sinarka (Shiashkotan Island ): Satellite images showed steam-and-gas emissions from Sinarka on 16 March and a weak thermal anomaly on 21 March.
Chirinkotan (Northern Kuriles): SVERT reported that during 19-21 March a thermal anomaly over Chirinkotan was detected in satellite images. The Aviation Color Code was raised to Yellow on 20 March.

Kilauea (Hawai’i): As the June 27th lava flow is no longer active in the vicinity of Pahoa town, HVO downgraded the volcano alert level for Kīlauea from WARNING to WATCH. HVO issued the following report: “The eruption of lava continues at both the Puʻu ʻŌʻō vent on Kīlauea Volcano’s East Rift Zone and in Halemaʻumaʻu Crater at the volcano’s summit.
Semisopochnoi (United States, Aleutian Islands): The Alaska volcano observatory (AVO) detected significantly increased earthquake activity under the volcano and warns of a possible eruption: “Earthquake activity that began in January continues, and has increased in intensity over the past few days. In addition, we have detected brief periods of seismic tremor, which can indicate movement of magma or magmatic gases. Thus we are increasing the aviation color code to YELLOW and the volcano alert level to ADVISORY.” (AVO)
