Glowing lava bombs showered the entire cinder cone and a considerable area of the island, as visible in the PVMBG surveillance webcam. Both explosions generated perpendicularly rising ash-abundant jets, about 800-100 meters above the vent, which extended northwest.
Eruptions occurred within a short time span range at 20:54 and 21:08 local time.
