A swarm of earthquakes at depths around 15-20 km has been going on under the SW flank, suggesting magma could be rising from deeper reservoirs into the volcano's shallower storage areas.
Tremor has been showing a rising tendency, but so far, no particular eruptive activity has been observed.

Since about an hour ago, some relatively strong explosions re-appeared to occur at the New SE crater. This could be a signal that it is heading towards a new paroxysm in the near future.
Tremor continues to rise slowly. The next days (if not hours) will probably give the answer. -
