A large vulcanian explosion happened on Friday afternoon (around 17:30 local time), generating an ash column that rose approx 4 km and generated a pyroclastic flow on the eastern flank.

This explosion was the first significant event since a similar event on 26 Jan. During the interval and since the explosion on Friday, the volcano has had only few and very week ash puffs at irregular intervals of average 8-12 hours, with no visible ejecta nor incandescence from the crater.
Whether the recent phase of relatively frequent and very strong vulcanian explosions is gradually coming to an end because of decreasing supply of fresh, viscous and very gas-rich magma, or whether the magma supply still continues at steady (although it seems lower) rate and more strong explosive activity is going to occur in the near future is left to speculation.
