The activity at the volcano has increased over the past few days.
From the recent short wave infrared (SWIR) satellite image, it seems that the lava effusion from the summit vent has intensified as it has advanced its length along the southwestern Kozyrevsky drainage. A night-time glowing steam accompanies the effusive eruption at night.
Near-constant strombolian activity atop the summit continues with mild spattering and the lava flow. Glowing lava spatter is constantly being ejected to approx. height of several dozen meters above the crater.
