In particular, there are two active flows relatively close to the vent which have been heading out towards the southeast and formed a small almost closed bay with green-orange discolored water inside. The water color is a result of dissolved volcanic gasses and lava fragments in suspension.
In addition to the ongoing lava effusion, strombolian explosions occur from the main vent as well, which has built a small perfectly circular cone.

Ash plumes to altitudes of 4,000 ft (1.2 km) were reported during the past days. These could have originated from more violent water-magma interaction (phreatomagmatic activity) or simply stronger strombolian explosions. Read all
