Eruptive activity of some sort continues at the volcano. This is evidenced by a strong thermal signal detected and a gas plume extending south of the small island, both detected on satellite imagery.
Contrary to nearby Chikourachki (that started to erupt 29 March), Alaid seems not to have produced any ash recently; no such darker-colored fresh deposits can be seen on the snow-covered flanks or in the plume. This suggests that the activity, at the moment, is non-explosive and confined to the summit crater, perhaps in the form of a small active lava lake.
