Activity remains at medium level, with frequent small and sometimes larger strombolian explosions from several vents. Gas emissions, volcanic tremor and other monitoring parameters show no significant variations.
La Palma (Canary Islands (Spain)): The eruption has been a little bit today, at least at the surface, while internal activity remains similar. Lava fountaining activity at the vents continues, but less intense compared to the past days. The ash and steam plume reached only little more than 1,000 m altitude today, although this is partly due to stronger eastern winds that push the plume down and over the ocean.
Lava effusion continues, but it is difficult to estimate the amount erupted as most of it is going into the tube system.

Yasur (Tanna Island, Vanuatu): The volcano has been very active recently. Strombolian-type explosions are rather strong and sometimes produce dense ash plumes rising several hundred meters.
Visitors are warned from approaching the crater rims where the risk of being hit by lava bombs is elevated. Some of the recent ash emissions have been strong enough to trigger notices by Darwin's Volcanic Ash Advisory center to warn aircraft in the area.

Soufriere Hills (Montserrat, West Indies (UK)): (26 Nov) The activity of the volcano continues at low values.
The large size of the lava dome and unstable hot lava material is prone to collapse into hot rock falls, which in turn develop into very dangerous pyroclastic flows and may travel in Plymouth town direction. Pyroclastic flows are deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes.
