Last evening, following hours of intense activity from at least four vents, parts of the western crater walls at the vents collapsed and gave way to short-lived floods of lava on the slopes of the cone. Whether or not the visible decrease is caused by a decrease of magma supply at the moment, remains unknown.

...25 Oct:
The eruption continues with little changes, and remains very intense. The active cone shows strong explosive and effusive activity; in particular, the summit vents have been producing spectacular lava fountains and generate an ash plume that rose to 3,800 m this morning. Several surface lava flows have been observed flowing from the cone.
The mixed explosive-effusive activity paired with high rates of magma reaching the surface causes frequent small and sometimes larger changes of the geometric configuration at the growing cone, as rapid accumulation works against the forces of gravity, drag of material ejected and flowing away and parts that become undermined by formation of tubes etc.; currently, at least 4 or 5 vents are active aligned in a row, with different behavior as the magma pressure varies with the height of the vents themselves and the complex interactions of the rising gasses and the fluid magma in the conduits.

La Palma (Canary Islands (Spain)): The intensity of the eruption increased. Since the last update, the at least 4 active vents have been generating violent pulses of lava fountains with ash columns rising to approx. 3 km, as well feeding both surface lava flows directly from the vents as well as fueling the hidden-from-view lava tubes that transport most of the lava to active areas of the flow field downslope. ...
