Lava dome growth continues. This morning, an explosion and/or a partial collapse produced a volcanic ash cloud rising to 15,000 ft (4.7 km) altitude this morning by VAAC Tokyo. ... [mehr]

Although tremor continues to decrease very slowly, KVERT reports that fluid lava is still being erupted from the vent on the southern fissure. MODIS satellite data still show a large hot spot, confirming that the eruption might be longer lasting than thought. [mehr]
Activity continues with little changes. Video data showed that the lava dome is still active and produces incandescence and hot avalanches on the western and eastern flanks. Strong and moderate gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano. (KVERT) [mehr]

KVER reports no change in the ongoing eruption of the volcano and ongoing high tremor values at levels similar to the past weeks. Recent field reports however suggest that the eruption continues its slowly declining trend and might actually be ending soon. ... [mehr]

The eruption continues to produce lava flows from the Southern fissure on Tolbachinsky Dol. KVERT reports strong tremor at a very gradually decreasing rate over the past weeks. [mehr]
The slow growth of the lava dome continues with no changes reported by KVERT: Moderate seismic activity, incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong gas-steam activity accompany this process. [mehr]

Volcanoes of KamchatkaThe Kamchatka Peninsula (Russia) is one of the most volcanically active volcanic places on earth, second only perhaps to Iceland and Hawaii. In this part of the Pacific "Ring of Fire", there are over 100 active volcanoes (the Smithsonian Institution lists 109) and about 30 volcanoes that have erupted recently, in addition to hundreds of smaller monogenetic vents (i.e. that have formed during one single eruption)
The active volcanoes form a 700-km long volcanic belt from Shiveluch in the north to Kambalny in the south. The vigorous volcanism on Kamchatka, like that of the adjacent Aleutian and Kurile island arcs, is produced by the subduction of the Pacific plate under the E margin of the Eurasian plate.
During the past 10,000 years, at least about 30 very large (so-called Plinian) eruptions have occurred in Kamchatka, i.e. eruptions that have ejected more than 1 cubic kilometer of magma. With this record, Kamchatka is by far the place on earth with the greatest frequency of large explosive eruptions.
The most active volcanoes on Kamchatka are Klyuchevsky, Shiveluch, Karymsky and Bezymianny.
