An increasing trend of the activity peaked with intensified quakes during the past 24 hours. Volcano-tectonic earthquakes were located at shallow depths between 3 and 6 km, of which the largest was recorded with magnitude M 2-3. Earthquakes likely reflected magma intrusions and migration under the surface.
Therefore, the local observatory made decision to rise the Aviation Color Code and Volcanic Alert Level to Yellow.
