Volcanos

Roundup of Global Volcanic Activity:

Kizimen (Kamchatka): The lava dome remained active and produced hot avalanches on the western and eastern volcanic flanks. Moderate seismic activity and strong and moderate gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano. (KVERT)

Shiveluch (Kamchatka): Seismic activity has decreased, classified as weak by KVERT. This suggests the active dome is in a phase of relative calm.

Tolbachik (Kamchatka): No end of the eruption is in sight. Lava continues to be erupted from the southern fissure. KVERT reports no significant changes and tremor levels have remained stable over the past 2 weeks.

Sakurajima (Kyushu, Japan): The volcano is back to about 1-2 explosions of moderate size per day.

Manam (Papua New Guinea): Ash plumes at 8,000 ft (2.4 km) altitude and extending to the NW were observed on satellite images (VAAC Darwin).

Veniaminof (Alaska Peninsula, USA): Activity has continued over the past days with little changes. Direct observations are difficult, but for the first time, some incandescence from the central cone was observed on the webcams yesterday. This is likely due to the presence of a lava flow and/or spattering from a vent.

Pavlov (Alaska Peninsula, USA): The eruption continues at low levels. Seismic tremor and occasional explosions are being detected in seismic data and indicate that minor ash emission is likely occurring, although no ash plumes were detected on satellite data over the past day. Elevated surface temperatures at the volcano have been observed in satellite data over the past 24 hours indicating lava at or near the surface. (AVO)

Popocatépetl (Central Mexico): The volcano has remained at moderate levels with frequent but mostly smaller gas-steam-ash emissions at a rate of approx. 3 per hour. Plumes reached about 1 km above the crater. According to a local press article, some US airlines (United, AA) decided to temporarily use alternative airports instead of Mexico's International Airport (AICM) as a precaution against encountering ash. AICM itself reports that so far no ash so far has been detected at/near the airport.
