What's going on?
You know that noted very weird 'seismic event' for Atlantic based on Magnitude;
Focused region big ratio of researchers after this event...At this point,emphasizing to selective 'seismic swarm conditions'for LaPalma Province of Canary Volcanic Islands Community as regional;

Note.I have not been observed any informations about such a event(M6.0 env) on catalog informations of USGS.Similarly,magnitude information of this env. by EMSC data is not observing.
Also, I sign to very selective development as vertical thickness of gravimeter timeseries between 9/12-9/17;
And,as predicted,explosion news about Cumbre Vieja!!!!

Update(12/4):
Yesterday's trend seems to continue - less vigorous activity visible at the surface and less earthquakes today (only 24 quakes from magnitude 3.0 or above, the largest a 4.2 event in the past 24 hours), but at depth, a new surge of magma might be preparing itself. This is shown by increasing inflation.
Volcanic tremor remains at strongly fluctuating moderate levels.
12/6 Update:
During this evening's press conference, the latest map was published showing the current state of lava flows including the new ones from the past days and the fissure that opened yesterday shortly after noon.
Lava effusion continues also without significant changes. Most lava is coming from vents west of the main cone and directly entering the tube system. Some of it breaks out to form a prominent channeled surface flow in the central part of the lava flow field, which is branching off in the area of Todoque and changes direction towards the southwest from there, along the flow labeled #11 and joining with flow #9 to feed the first and largest lava delta (although no lava seems to be actively reaching the sea shore). On its way, it continued to eat away at left-over islands of land so far not touched by lava flows.
The lava flow from the new vent system west of the Cogote Mountain remains active as well. It, too, is mostly inside a tube on the first section of its path, then emerges to form surface flows that spill over the cliff in the Las Hoyas area and spills onto the lower coastal flat land.
The area covered by lava flows has increased by 27 hectares during 36 hours and now is estimated to be 1,182 hectares, with a maximum width of 3,350 meters. The new lava deltas combined are about 48 hectares in size.
Damage to infrastructure since the beginning of the eruptive process, according to information provided by the Copernicus satellite, amounts to approximately 3,039 buildings, of which 2,881 are be completely destroyed and 158 damaged.
No significant changes in ground deformation occurred. Volcanic tremor and seismic activity have been low. During the latest 24 hours, there were 1 quake of magnitude 4.0, 6 quakes between 3.0 and 3.9, and 26 quakes between 2.0 and 2.9 under the volcano.
It looks as if finally, the eruption might be in the stage of dying down slowly although nobody can predict a precise time frame how long it may still last. A new burst of more intense activity if also still possible any time.

Update Dec 9:
The eruption continues more or less in the same way as yesterday - intermittent strombolian-type explosions and sometimes stronger ash emissions occur at the main vents of the cone. Ash plumes have reached altitudes around 3,700 m and drifted towards southerly and southeasterly directions.
Lava effusion remains stable, concentrated from vents near (or beneath) the cone, where they enter tubes, to break out as surface flows further downslope, mainly in the central part of the flow field, where lava flows continued to initially travel through a narrow and the widening channel, before spreading into various arms. One of them is now covering the lava flows that had erupted from the fissure vents west of Montaña Cogote. The latter have practically ceased to be active.
Active lava flows have continued to descend the steep cliff onto the the coastal flat of Las Hoyas, but without reaching the sea itself. Thick smoke was rising from burning plantations in the area this morning.
An increase in sulphur dioxide (SO2) emissions was reported today. Earthquakes have picked up a bit as well, especially in the deeper layer of 30-40 km depth. During the past 24 hours, there were 13 quakes of magnitude 3.0-3.6 and 27 quakes between 2.0 and 2.9.
Volcanic tremor remains low, at similar values as yesterday. No significant deformation has been recorded.
The following video by IGN shows the ground cracks on the flank of Montaña Cogote associated with the lavas that had erupted there last week (but now ceased):

UPDATE 12/10:
The eruption continues along a very slowly decreasing path. Activity today has been more or less as yesterday, but a bit weaker at the vents.
Only sporadic explosive activity occurred, occasionally producing ash plumes that rose a few hundred meters.
Volcanic tremor remains low at similar amplitude as in the past days, but with less and less fluctuations. Lava continues to effuse into the tube system beginning at or near the cone, and is mainly feeding the same flow as in the past days, which emerges onto the surface in the central part and branches off mainly towards the southwest. No significant enlargement of the lava flow field has occurred in the past days.
Other parameters also show a decreasing trend at the moment, including gas emissions, ground deformation and seismic activity. The National Geographic Institute (IGN) reported 32 earthquakes during its latest 24-hour reporting interval. The strongest one was a magnitude 3.6 event at 12:09 UTC at a depth of 37 km.
Update 12/12:
https://youtu.be/z_Y5ol7WDEE
Update 12/13:
Around noon local time, a sudden large explosion occurred at the main crater of the cone, producing a steam and ash plume that quickly rose to estimated 5,000-6,000 meters altitude.
The event was likely a so-called vulcanian explosion, typically caused when a larger plug in the upper conduit has formed and is suddenly thrown out when gas pressure underneath overcomes a threshold (comparable to a cannon-shot mechanism).
Today's explosion likely might be due to the fact that the conduits have gradually been closing up / filling with debris in their upper parts as supply of rising material is less abundant. This fits with the model that the eruption has entered its final waning stage, but also creates highly dangerous conditions, because such explosions could (and likely will) repeat in the days to come.
Apart from this, the eruption - now on its 87th day of activity being the longest in recorded history on La Palma Island - has continued at low levels similar as in the past days. There is now mainly steaming, with only occasional smaller explosions, at the main cone, while lava effusion continues at reduced rate. The arriving lava first goes into the tube system, and feeding flows in similar areas as during the past days overlapping older flows.
Seismic activity has been low, with only 24 quakes detected during 24 horus, the maximum being only a 3.2 event. Deformation and tremor remain basically unchanged at low values, although the explosion earlier resulted in a short-lived intense tremor peak.
Update 12/14:
https://youtu.be/XzWTW0K-ZEE
Updtae 12/16:
No new activity has been reported at the eruption site since it ceased yesterday. Chances increase that the eruption is over, although this is far from certain (read below for more background).
UPDATE 12/26:
ERUPTIVE EPISODE ENDED AFTER ALMOST THREE MONTHS
UPDATE 5/8:
You know that I defend harshly mechanic and heat effect transforms on block models...Because,this chapter is supplementary with lab experiment!!!!!

Where,We must analyse thermal stru dev focusing fracture patern dev with slowmotion👍🙏✋For this aim,I will cite to add role of a 'thermal imaging system' 😐
