The activity of the volcano continues to be elevated since 15 March as the increase of seismic activity and slight inflation have been recorded.

Continuing gas-steam emissions were observed by surveillance cameras starting about 18:22 local time today as can be visible in the attached video below. This may indicates elevated fluid movements of gas, water and possibly rising magma under the surface, typical signs for an upcoming eruption.
The seismic activity continues at fluctuating levels.
The slight ground deformation on the western flank of the volcano was recorded on 15 March and goes on since mid-May again.
The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 2 km distance from the main crater.

On 23 March JMA raised the Alert Level for Asamayama to 2 (on a scale of 1-5), noting slight inflation on the W side of the volcano since 15 March and an increase in the number of daily volcanic earthquakes that have occurred since 20 March (36 recorded on 20 March and increasing to 77 events by 1500 on 23 March). After 23 March the number of daily volcanic earthquakes began to fluctuate, decreasing to 15 on 28 March and then 23 by 1500 on 29 March. The sulfur dioxide emission rate was 800 tons per day (t/d) on 22 March, 400 t/d on 24 March, and 700 t/d on 25 March, compared to the previous measurement of 200 t/d on 25 February. ... Read all
