The volcano reactivates after the break
The La Palma volcano once again expels a column of ash after being for several hours of tranquility and the re-emission of lava in the main cone is also confirmed


The La Palma volcano once again expels a column of ash after being for several hours of tranquility and the re-emission of lava in the main cone is also confirmed, as confirmed through social networks by the Instituto Volcanológico de Canarias Involcan. After a stop in the volcanic activity at 8.30 a.m. as well as the emission of ash and smoke from the volcano that has been erupting for eight days on the island of La Palma, a column of smoke has again reappeared at this time and the emission of lava has also been resumed.

This morning the Volcanological Institute of the Canary Islands, Involcan, had confirmed that the volcanic tremor of the La Palma eruption "had almost disappeared" as well as the strombolian explosive activity.

Seismic activity in the south and earthquakes
In addition, seismic activity has been reactivated on the morning of this Monday on the island of La Palma and has moved south, with 16 earthquakes located in the north of Fuencaliente, according to the National Geographic Institute (IGN), episodes that coincide with an apparent stoppage in the Cumbre Vieja volcano, which has temporarily stopped emitting lava, smoke and ash, at the same time as a significant fall in the volcanic tremor.

The most intense Earthquake was located at 06.05 hours and at a depth of 10 kilometers, and in general, all are above magnitude 2 and at depths that range between 9 and 13 kilometers.

Scientists analyze this stoppage of emissions at Cumbre Vieja and from Involcan they point out that in the last few hours the volcanic tremor "has almost disappeared", as has the explosive strombolian activity.

The eruption suddenly paused this morning: surface activity at the vents and volcanic tremor, a measurement of magma movement towards the surface, ceased.
Whether this indicates the end or just a pause in the eruption is too early to determine, but at this stage, it is better to asume that it is only a pause: Earthquakes have picked up again a bit, which suggests that magma pressure has increased underground and magma might be trying to find new pathways. This could lead up to a resumption of activity, either from new vents or by re-using the existing one.
During the past 24 hours, there were 17 quakes of magnitudes from 2-3, the largest a 3.2 quake 11 km south of Los Llanos de Aridane at 8.05 a.m. this morning.
Last night, activity actually picked up and we observed very strong and tall lava fountains until about 1 a.m., although we had the impression that the ratio of lava and gas was smaller in the fountains than earlier on. After this, during the early morning hours, fountains decreased and abruptly stopped.
The next few days will certainly be interesting to follow what happens.

They recommend not approaching the coast of Tijarafe due to landslides
The local corporation of Tijarafe asks its neighbors not to go near the coastal points during the next few days "unless it is strictly necessary."

The Tijarafe City Council has issued this Monday the recommendation not to approach the coast due to possible landslides related to the new La Palma volcano.

The local corporation of Tijarafe asks its neighbors not to go near the coastal points during the next few days "unless it is strictly necessary."

This call, as he explains on social networks, is due to "the latest landslides" recorded on the coast of the neighboring municipality of Tazacorte.

The exclusion zone for navigating the volcano is moved to the north
The Maritime Captaincy of Santa Cruz de Tenerife has agreed to move to the north the exclusion zone for navigation due to the risk of lava falling into the sea of ​​lava from the new volcano of La Palma, which goes from La Bombilla to 0.2 miles to the south from the port of Tazacorte.

In addition, the maneuvering of ships entering and leaving the port is restricted in the area of ​​the tip of the dike and, in the event that the lava spill into the sea is less than 1.2 miles from the mouth, it will be foresees a possible closure of the port, the Ministry of Transport, Mobility and Urban Agenda reported in a statement.

The measure of modifying the exclusion zone, which remains two nautical miles from the coast , has been recommended by the La Palma Volcanic Emergency Plan (Pevolca).

From this Monday you will be able to navigate in the area south of La Bombilla.

The Maritime Rescue means, the Punta Salinas height tug and the Alphard rescue, are maintained in the area to control the new exclusion zone.

This measure, says the Ministry of Transport, is preventive, given the possible arrival of volcanic flows into the sea, with the inherent risk for navigation.

If this were to occur, according to forecasts, it would do so north of Los Guirres beach.

It is also about preserving security in the port of Tazacorte so that it is not affected by the adverse phenomena that could be generated in the contact of the lava with the sea while maintaining its activity.

It is a port area with fishing and recreational activity and with the capacity for berthing merchants.

Likewise, it abounds, "the objective is to raise awareness among the population, being aware that the attractiveness of this phenomenon can generate a concentration of vessels in the areas surrounding the point where volcanic flows are expected to reach the sea."

THE PALM.- CONTINUES THE SISM-VOLCANIC WARNING UNDER THE OLD CUMBER VOLCANO.- A lot of seismic movements are seen in the Earthquake although they are not as strong as detected this early morning, where at 4 in the morning has started another important seismic upturn, which I already spoke about this morning.
This swarm is located in the same area where several days ago the ultimate swarm began that ended erupted on September 12th that spoke in note 405, make your accounts and see that I'm taking about 7-8 days in eruption, we will have to keep an eye on what's left and what's coming our way.
Regarding historic Events, the San Juan Volcano in 1949 did the same thing, don't miss the report of many years ago that tells us very familiar things and remind us of what we are living today. Knowing history to know what a volcano does is vital if it exists to know what it will do in the future, in the coming days if you prefer... (Enrique)

Geologists warn of the danger of the effects of the arrival of lava with the sea: splinters can 'rain'
The expert in volcanology from the Illustrious College of Geologists (ICOG), José Luis Barrera, has highlighted that the stoppage occurs due to "lack of supply" in the magmatic cava, about two kilometers deep.

EUROPA PRESS09/27/2021 · UPDATED 17:59


The contact of the lava with the sea is dangerous for the nearby population, due to the toxicity of the gas mixture but, also, because it could vitrify, be incorporated into the cloud and fall into a nearby environment in the form of splinters, according to has explained the expert in volcanology of the Illustrious College of Geologists (ICOG), José Luis Barrera.

Speaking to Europa Press after the specific stoppage of the foreign activity of the Cumbre Vieja volcano in La Palma, which has been in full eruption since last Sunday, September 19, he stressed that this stoppage is caused by "lack of supply" in the magmatic cava, about 2 kilometers deep.

However, he added that since last morning 16 earthquakes have been recorded, further south of the volcano, about 8 or 12 kilometers deep. In this way, he does not rule out that volcanic activity could open at another point on the island, although he admits that this possibility, for now, cannot be confirmed.

Thus, it exposes that the eruption is caused by gases, which are what carry the magma, but if there was a lack of gas supply in the magmatic cava - two kilometers away - then it could not go outside. But once the gases have pushed back into the magma, lava has started to come out again.

"It cannot be ruled out that another point will open on the island because the magma is looking for another outlet, but neither can it be known how long the volcano will be active," adds Barrera, who points out that 16 seismic movements have been recorded last morning. between 9 and 12 kilometers deep, in the Fuencaliente area, which shows that the volcano has not stopped.

“There is no new element to think that the eruption is over. It cannot be known and there will be no indication of it until the entire chimney starts to go out and the seismicity disappears completely ”, he assures.

Thus, remember how in the weeks before the eruption began, seismicity began further south and from there it migrated north, to finally open in Cumbre Vieja.

Regarding the possible arrival of the volcanic flow to the sea, he points out that the width of the front of the lava is one kilometer, once the two routes have been joined but that in the central part it is dammed and until it does not exceed that deepening will not regain more speed. *

LAVA SHEARS WILL FLY
Once it reaches the sea, it warns of the “dangerous effects” because the volcano's own gases will join the water vapor from the sea, which sometimes includes chlorine and fluorine compounds, in addition to the salinity of the environment itself. But the most significant thing is that the lava, which is at a thousand degrees Celsius when it reaches the water, at about 24 degrees Celsius, will cool down and if this cooling occurs very quickly - according to the contribution of lava - the lava will not crystallize but rather will be vitrified.

This vitrification process will retract the body of lava, which will break into shards that will jump from the surface and mix with the column of gases.

The expert in volcanology explains that this is the reason why the expected area of ​​the arrival of the lava has been limited, so that the boats do not approach less than two kilometers from the coast, nor the population, although this area Exclusion could vary depending on how the winds vary. "It would be as if it were raining crystals," he compares.

Another of the harmful effects of the arrival of the volcanic flow into the sea will be the destruction of part of the fauna and flora wherever it is deposited, but trust that after a while everything will return to its place. "We clearly saw that in the underwater volcano of La Restinga, where flora and fauna returned soon after," he concluded.

This Monday the National Geographic Institute has reported the seismic swarm registered in La Palma, with about 16 earthquakes registered up to 14 kilometers deep.

The highest magnitude, 3.2, occurred at 06.05 in the Canary Islands. The value of the mean amplitude of volcanic tremor remained around the mean values ​​of the eruption during Sunday, when it began to increase sharply and reached its maximum value around 00:00. Throughout the night it descended to coincide with observations of the decrease in flow at the surface.
