03/10/2021 h Canary Islands.- LA PALMA ISLAND ERUPTION.- CONTINUES THE SISM-VOLCANIC WARNING UNDER OLD CUMBER WITH HUNDREDS OF FEARS, ONLY GREATER MAGNITUDE ARE LOCATED BY THE NOISE DEL TREMOR.- Seismicity continues and hundreds of tremors are appreciated in the
Earthquake under old summit several of them 3 or more. Highlights a magnitude 3.5
Earthquake tonight. In conclusion, the magma is finally progressing and seismicity continues to increase the release of released energy, as seen in the weekly graphic of the accumulated released seismic energy.

You can tell how it happened in the underwater eruption in El Hierro that goes to pulses, which are seen in the sky when it emits the gases and ash, but not only in the volcano, the seismicity goes to blows and looks very well in the function of singer, with fillings of steps in the times that is quiet and climbing steps when seismic swarm seismicity come in. This looks pretty good on the graphics of the last 24 h of the released seismic energy accumulated.
On the chart since the eruption of the last 30 days of the collected released seismic energy, you can see that this second swarm has already released between dicks and flutes almost the same amount of energy as the first swarm that ended with the volcano opening, giving us insight on the energy available and doesn't look like it's going to stop, rather otherwise.
But in the seismograms and spectrums two more things are observed, the noise of the tremor this midnight has fluctuated and has been with more intense periods, due to the strombolian explosions and some hydromagmatics that have occurred at the various eruptive points of the volcano.
′′ As for what happens at the volcano's emission points, Isaac described it wonders:
′′ Strombolian pulses follow and volcanic cone transformation is accentuated. Here we see as the fruit of those pulses, the most effusive mouth suffers a fork in its lava output channel. A relatively powerful explosion is even appreciated, followed by a slight rest. The eruption continues and the volcano is slowly changing its shape."

As for flow 7, it must have continued to flow through the N part of the existing laundry and at this time I do not know where it is, although it had slowed down a lot so I do not think it has made much progress.. between 100 and 300 m at the most, as soon as I have more specific data I'll update it. I leave you this awesome video of this flow.

And delta, the cliff lava continues to fall down by 3 sites, so that, now 28 acres of new land, it goes at a rate of 7 acres a day with a thickness on the front of the flow about 30 m about 500 m away from the cliff and a width of about 600 m in total.
Now we only have to wait for the magma pulses or arreons that are rising through the dikes (vertical fractures or almost full of lava or magma) and leaving and the seismicity that comes along this line and although they announce to come up by the increase in seismicity in the deep area of the island 10-12 km, not many. We'll see.
These vertical dikes normally have their origin in a sheet or layer of magma that forms under the island as a horizontal dam or ′′ chair ′′ that lifts the island as if a hydraulic cat was treated, which has already passed in El Iron (stayed more than 40 cm lifted after the eruption) and makes the starting point of those vertical dams by which it starts to upload material after fracturing the rock of the roof of that flat reservoir or chair, on the way to the surface and where It usually stays forever good part of the material, causing the island to rise.
