VONA/KVERT DAILY REPORT
Kamchatkan and Northern Kuriles Volcanic Activity
April 06, 2013, all time is UTC

SHEVELUCH VOLCANO (CAVW #1000-27-)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Color Code is ORANGE

Moderate seismic activity of the volcano continues. According to video data, hot avalanches and a strong gas-steam volcanic activity were observed. Satellite data showed a thermal anomaly over the volcano.

PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-)
55.83 N, 160.39 E; Elevation 10119 ft (3085 m)
Aviation Color Code is ORANGE

Strong seismicity of the volcano was registered. An amplitude of volcanic tremor was up to 4.5 mcm/s. Explosive-effusive eruption continues: lava flows continues to effusing from the Southern fissure on Tolbachinsky Dol. Incandescence of the lava flow deposits, and strong gas-steam activity accompany this process. A big thermal anomaly was noting on satellite images at the northern area of Tolbachinsky Dol. And first a weak thermal anomaly was detected on satellite images over the crater of Plosky Tolbachik volcano too.

KIZIMEN VOLCANO (CAVW #1000-23-)
55.13 N, 160.32 E; Elevation 8151 ft (2485 m)
Aviation Color Code is ORANGE

Moderate seismic activity of the volcano continues. Video and satellite data showed a growth of an extrusion at the volcano summit continues. Incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano.

KARYMSKY VOLCANO (CAVW #1000-13-)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE

There was not seismic data by technical reasons. Satellite data showed a thermal anomaly over the volcano.

BEZYMIANNY VOLCANO (CAVW #1000-25-)
55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW

Strong seismic activity at Tolbachinsky Dol obscured seismicity of Bezymianny. According to video data, a moderate gas-steam volcanic activity was observed. Satellite data showed a thermal anomaly over the volcano.

GORELY VOLCANO (CAVW #1000-07-)
52.56 N, 158.03 E; Elevation 5996 ft (1828 m)
Aviation Color Code is YELLOW

Moderate seismic activity of the volcano continues. According to video data, a moderate gas-steam volcanic activity was observed. Satellite data showed a weak thermal anomaly over the volcano.
