Shiveluch volcano news and updates
At shiveluch volcano, the lava dome continues to grow. At any time explosions could produce ash plumes that rise as high as 8 km (or 25,000 ft.) ASL.
Shiveluch volcano started a new eruption on Thursday-Friday night. An ash plume has reached 7.5 km above sea level, and a lava flow is descending 15 km from the summit....more
The explosive activity at Shiveluch volcano is increasing and the alert level has been breifly raised to its highest state of RED between 8 and 9 July. Moderate explosions took place during the past week, some of which produced ash plumes of up to 7 km a.s.l. Seismicity at the volcano is increasing.

The lava dome inside Sheveluch volcano's summit crater continues to grow. Although no explosive activity was registered during the past week, stronger eruptions that produce ash plumes several km in height could occurr at any time.
Sheveluch volcano remains in strombolian activity, with explosions that produce ash plumes some 1-2 km above the crater. At the moment, scientist have no data on the seismic activity in the area of the volcano, because the station at Baidarnaya, eight kilometers from the peak of Shiveluch, was destroyed by a lahar on February 27-28.
As the Russian agency Novosti and the Alaska Volcano Observatory report, Sheveluch volcano, Kamchatka (Russia), is remains highly active. After the violent eruption on February 27, 2005, that destroyed the upper parts of the lava dome, thus lowering the total height of the mountain by 200 m, the lava dome has re-grown by more than 50 m during the past 20 days and keeps increasing. The rapid growth, caused by continuing influx rate of fresh magma, triggers frequent hot rockfalls and small pyroclastic flows.
The Russian news agency Novosti reports a strong eruption by Sheveluch volcano on March 23, 2005, that destroyed a camp of vulcanologists and the seismic station at Baidarnaya, located eight kilometers from the volcano.
According to this report, a significant part of the lava dome at the summit has collapsed, and generated a massive flow (probably a pyroclastic flow, not a lava flow as stated ?) that travelled down the slope more than 20 kilometers long. There were no people in the area during the event. According to the news agency, this eruption would be the largest since Sheveluch's disastrous eruption of 1964.
