Lava branches off into several lava arms mainly toward the eastern and southern flanks (image: Landsat 8-9)

The elevated effusive eruption at the volcano continues.

The Landsat8-9 satellite acquisition over the volcano revealed that multiple lava flows emerge from the summit cone. There are three-to-four lava branches, of which one main lava arm continues to descend over the eastern flank.
The remaining two or three lava flows are emanating from the main one towards the southern slopes.
