Volcanic activity worldwide 24 Sep 2021: Fuego volcano, Karymsky, Popocatépetl, Reventador, La Palm...

La Palma (Canary Islands (Spain)): Explosions have increased during the past hours, often generating shock powerful waves that can break glass in up to 3 km distance. A new effusive vent has been reported to have opened on the flank of the main cone.

As a reaction to the increase in explosive activity, new evacuations have been ordered for the areas of Tajuya and the remaining parts of Tacande.
...24 Sep:
The eruption has been relatively stable during the past 24 hours: sustained, fast-pulsating lava fountains are rising from the vent, reaching several hundred meters and generating an ash and steam column that rises near vertically to estimated 3-4 km elevation.
The fountaining is remarkably stable, although at times briefly interrupted by giant lava bubble explosions that eject glowing lava bombs in all directions to more than 1000 m distance, often showering the whole cone with red-hot lava ejecta.

Some of these produce cannon-shot loud detonations with visible shock waves that are felt in many kilometers distance. Some people confused them with earthquakes.
Volcanic tremor overall is stable and still high, perhaps with a slightly decreasing overall trend. Earthquakes have mostly ceased and inflation seems to have stalled. This indicates that the eruption has likely found a stable phase.

...24 Sep:
The effusive-explosive eruption of the volcano continues at elevated levels.
A strong explosion, starting around 05:40 local time, triggered a pyroclastic flow that traveled over the Ceniza ravine reaching length of at least 4-6 km. Ash plumes separated from the pyroclastic density current and formed so-called phoenix clouds. The eruption column rose to an altitude of 16,000 ft (4,900 m) and extended to the west of the volcano. 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.

...24 Sep:
Seismic recordings of INSIVUMEH's instruments detected an increasing trend of the activity at the volcano this morning.
Elevated strombolian activity started to produce two new lava flows slowly advancing towards Ceniza and Trinidad ravines. Lava continues to keep the flow active, currently about 250 and 350 m long.

The activity quickly intensified a few hours later, accompanied by a strongly rising signal of volcanic tremor indicating rapid magma flux towards the surface.
Collapsing parts of flows generated small-to-moderate incandescent avalanches which traveled towards Ceniza, Trinidad, Taniluyá, Santa Teresa and Las Lajas direction.
