Veniaminof volcano (Alaska): activity summary for the past week

Friday Jul 26, 2013 23:11 PM | VON: T

From AVO's weekly activity update:
"Nearly continuous, gradually fluctuating volcanic tremor and occasional explosions have been observed in seismic data from Veniaminof Volcano throughout the past week. Elevated surface temperatures at the intracaldera cone also have been observed in satellite data throughout the past week. When viewing conditions permit, incandescence at the cone has been observed in night-time web camera views. Day time web camera views also showed that low-level ash and steam emissions have continued throughout the week. A pilot report from 8:00 AM AKDT July 25 described an ash plume to 200-300 feet above the erupting cone and dispersing 15 miles to the south and a "river of lava" flowing from the intracaldera cone.
Over the past week, the low-level eruptive activity characterized by intermittent effusion of lava and emission of minor amounts of ash and steam has continued. Ash emissions have been very minor and rates of lava effusion have fluctuated slightly throughout the week. This level of activity may persist for several more weeks to months. AVO has observed nothing in any of the data streams we monitor to indicate that the eruption will intensify and become more explosive; however, this remains a possibility. Continued production of lava may result in more melting of the ice and snow in the vicinity of the cone, but thus far there is no evidence for outflow of water down Cone Glacier to the north of the cone.

Wednesday, Jul 24, 2013
AVO reports no changes in activity: continuous low-level volcanic tremor, elevated surface temperatures at the intracaldera cone, visible glow and low-level ash and steam plumes indicate that lava flows continue to be erupted, along with mild strombolian activity. [mehr]
