Veniaminof volcano (Alaska): continuing lava effusion and increase in seismic activity
Dienstag Jul 09, 2013 14:09 | VON: T
Current seismic recording from Veniaminof (VNHG station, AVO)A significant increase in seismic activity has occurred today, which could suggest that the eruption is gaining strength. During the past days, it continued at low but steady levels with no major changes.
AVO reported low-level volcanic tremor and a thermal anomaly as well as occasional observations of weak incandescence indicate continuing lava effusion. Explosive activity, if at all, is minor.

Small lava flows continue to be erupted from the intra-caldera cone, as seismic data (nearly continuous, low-level volcanic tremor) and satellite data indicate that show a hot spot around the cone. No significant explosive activity has been detected. [mehr]

Effusive and weak explosive activity continue. Volcanic tremor and small explosions continue to be detected in seismic data and satellite data continue to show elevated surface temperatures at the intracaldera cone. A light colored plume is rising above the cone to just above the rim of the caldera to about 8,000 to 10,000 feet above sea level and at night, a persistent glow is visible. (AVO) [mehr]

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. ... [mehr]
