An isolated small explosion occurred in the evening around 19:15 local time, generating a small ash plume rising a few 100 m and throwing some lava bombs onto the upper flanks. Apart from this event, no other explosions were observed during the night and the following two days. (Photo: Tom Pfeiffer)

The layers of the scoria cone are build up of black lava droplets with green olivine crystals, the latter being heavier than the former and hence getting left behind and accumulated during wind and water action (Photo: Ingrid Smet)

A light ash plume can be seen rising from the top of the volcano where the active vent of the 2018 eruption lies. The volcano forms a prominent landmark, rising to 2462 m elevation from near sea level out of the otherwise flat landscape of the Albay Gulf. (Photo: Tom Pfeiffer)

The helicopter keeps the engine running while we unload everything to return as soon as possible, before the weather worsens; fortunately, the rotor blades are at safe height. Karymsky volcano in the background emits a dense steam plume, while the sky is already covered with dense clouds. (Photo: Tom Pfeiffer)
