Volcanos

Roundup of Global Volcanic Activity:

Manam (Papua New Guinea): An eruption with a small ash plume was reported this morning and VAAC Darwin issued an advisory. A low level ash plume was also visible on Nasa's Aqua Modis image at 15:45 UTC.

Veniaminof (Alaska Peninsula, USA): The eruption continues. A lava flow is being erupted from the central intra-caldera cone, recent satellite images suggest as they show very high elevated surface temperatures in this area. Since about 10 hours ago, a seismic swarm and continuous tremor have appeared indicating probably an increase in this activity. No plumes were reported by AVO.

Pavlov (Alaska Peninsula, USA): No changes in activity were reported by the Alaska Volcano Observatory. Seismic activity continues to decrease and no elevated surface temperatures were detected in satellite images during the past 24 hours. No plumes were visible in satellite images, while web camera images show mostly cloudy conditions.

Popocatépetl (Central Mexico): A powerful explosion occurred yesterday at 13:23 local time, producing an eruption column rising about 4 km. This is so far one (if not the) largest single eruption in the present cycle of activity.

Fuego (Guatemala): Activity at all currently active volcanoes in Guatemala has been weaker today. The small new lava flow at Fuego was not mentioned in INSIVUMEH's daily reports, and only few weak strombolian explosions were observed since yesterday. No strombolian activity was seen or heard at Pacaya and only a small explosion is mentioned for the lava dome of Santiaguito. Seismic recordings were not available today.
