Agung volcano (Bali, Indonesia): strong explosion this morning, ash to 30,000 ft

Another explosion occurred at the volcano last night, at 01:38 local time this morning. A vulcanian-type eruption ejected lots of incandescent material to distances of at least 700 m from the crater and generated an ash plume that rose to 30,000 ft (9000 m) altitude and drifting south over Denpasar.
According to BVMBG, the eruption lasted almost 10 minutes, marking it one of the longest in the recent series of such vulcanian explosions.
A small earthquake swarm and slight inflation yesterday preceded the eruption.

At present, it is unclear whether the magma involved in the recent eruptions is the same as what had gradually accumulated in (and for a while sealed) the conduit of the volcano since the re-awakening of the volcano in 2017, or whether it is now a new, probably more fluid and hotter batch of fresh magma that has been rising from greater depths. In the latter case, an intensification of the so-far intermittent activity would be likely, while in the other case, activity would be expected to continue at similar levels and eventually gradually decline.
