Roundup of Global Volcanic Activity

Sinabung (Sumatra, Indonesia): Another large pyroclastic flow occurred yesterday morning. The flow traveled 2-3 km to the base of the mountain and produced an impressive coignimbrite ash plume that rose to approx. 4 km altitude. The volcano's eruption continues mostly quietly to effuse viscous lava, feeding a flow emplaced on the upper southeastern flank. At times, such as yesterday, it becomes too unstable and smaller or larger parts of it can collapse, generating dangerous pyroclastic flows.

Fuego (Guatemala): The recent, strong paroxysm ended Sunday. It had lasted 22 hours. CONRED reported that the volcano now returned to its typical intermittent strombolian activity with weak to moderate explosions. The lava flow towards the Trinidad and Ceniza canyon on its upper flank remains weakly active, although seems to be decreasing. Guatemala's international airport has resumed operations.

Piton de la Fournaise (La Réunion): The eruption continues without major changes. The volcano observatory OVPF reports low, but stable tremor levels. Webcam imagery from last night (before clouds obscure views) show that the eruption is mainly effusive with only weak explosive activity (weak spattering) at the vents. Currently, a small lava flow is active that extends approx 500 m from the base of the Dolomieu cone, enlarging the new lava field of partially overlapping flows at its base. The middle section of the lava flow is through a lava tube, making it invisible to the webcams.
