The last 24 hours had been characterized by 94 exhalations of steam, gas and a little ash. At the seismicity level, 68 minutes of harmonic tremor and two volcanoteconic earthquakes at 15:53 / M2,3 and 20:16 / M1,9 were recorded.

The activity remains under the Amarillo volcanic alert semaphore fase 2.

At Sheveluch, Kamchatka, the lava dome extrusion continues, with strong fumarolic activity, avalanches and night glow. The plume of gas and steam, a little charged with ashes, reached a height of 3,500 - 4,000 meters drifting west of the volcano west 52 km on 22 January.

On January 23, the KVERT reports a 4.500-meter plume drifting southwest.

The aviation code remains orange, with the possibility of ash explosions, with a plume reaching 10-15 km in height.

At Etna, ash emissions follow one another on January 22nd at two summit craters, the Northeast crater and the Bocca Nuova

A note from Prof. Carmelo Ferlito announces the opening of a new mouth in the central crater; it is about 40 meters northwest of the small gouffre opened in August 2016, and emits bluish gases, and is likely incandescent during the night.
