This episode has been accompanied by the continuous emission of water vapor and small amounts of ashes. According CENACOM, ash falls were reported in the city of Tetela, at the base of the volcano. After the train of explosions, seismic activity has declined and only smaller-scale explosions were present, in addition to small tremor episodes that were recorded for a total of 35 minutes.

At 7:32 p.m. yesterday an expiration generated a column with a height of 1 km and at 19:50 h was recorded incandescent episode, which reached up to 0.3 km .This morning two explosions were recorded, the first occurred at 08:45 pm, emitting a column of 1.6 km height with a moderate ash content, while the second occurred at 10:18 pm generating a column of 2 km in height.

Karymsky , Kamchatka :

54.05 N, 159,44 E;
Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE

Moderate explosive eruption of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.



Moderate eruptive activity of the volcano continues. Satellite data showed: ash plumes drifted about 150 km to the north-east and south-west of the volcano on March 27 and 29-30; a thermal anomaly was noting over the volcano on March 29; in the other days the volcano was obscured by clouds.

An ash plume was reported yesterday morning. The volcano has intermittent strombolian to vulcanian explosions, sometimes strong enough to produce ash clouds visible on satellite imagery.
