The Cumbre Vieja volcano, of which tomorrow Sunday will be two weeks since its eruption, has already affected a total of 1,005 constructions, of which there are 880 destroyed and 105 damaged or at risk of being destroyed, and it is not ruled out that today there are new homes affected. There is also 28.3 kilometers of unused roads and 201 people are still sheltered at the Hotel Princess, in Fuencaliente.
Also, lava flows have destroyed the last irrigation connection today that existed in the El Remo area, which has caused a major focus of white smoke that came from the vicinity, as a result of the lava coming into contact with the water. According to Cadena Ser, there are 3,000 people who have been left without water due to this incident.
This was reported at a press conference by the technical director of Pevolca, Miguel Angel Morcuende, who recalled that we are facing an eruptive process in which there is an associated seismicity, among other things, because the caldera containing the magma and causing holes, what it does is reorder itself and in the end it ends generating seismicity, a phenomenon consistent with the current volcanic process. In any case, Morcuende stressed that “we should not be thinking about other possibilities and, above all, we have to be calm in this regard”, because currently seismicity is not registering at a superficial level.
On the other hand, the technical director of Pevolca has once again asked citizens to do not bring more clothes or blankets, given that they are no longer necessary as there are enough of them, and he indicated that the transport of these items creates a problem because then triage has to be done and, above all, they take up a lot of space on the ships.
Carmen López, national responsible for volcanic surveillance of the IGN, has indicated that the Fissural eruption continues to show the same strombolian mechanism, alternating explosive and effusive phases, and also with simultaneous activity of both styles.
He indicated that the new stream that appeared yesterday has run westwards parallel to the main stream and has reached the end of the Los Campitos road at 09:00, establishing subsequent lateral contact with the previous streams. In addition, there are several active centers inside the main crater and two located in the northwest sector of the side of the cone. The scientific committee cannot rule out the appearance of new emission centers in the days of the eruption.
Depth of 35 meters
Carmen López pointed out that the fajana is at a distance greater than 540 meters from the coastline and it has already reached a depth of 35 meters, and the covered area reaches 27.7 hectares. Its lateral increase is observed in the last hours, both to the north and to the south. The sea plume continues and along the lava delta, producing clouds of water vapor and hydrochloric acid that concentrate in a small area around the contact between the lava and seawater.
Similarly, the fumarole field continues to be active and this morning, between 9 a.m. and 10 a.m., the opening of a small emission center for ash and gases. This fumarolic activity could favor the destabilization of the upper part of the cone and the repetition of phenomena such as those that occurred this morning. Also this activity, both explosive and fumarolic, can repeatedly change the successive processes of growth and reconfiguration of the cone.
The eruptive process can show episodes of increased and decreased strombolian activity and can also show phreatomagmatic activity. This morning, first thing in the morning, the height of the cloud of gases and ash in the cone was measured and it is around 4,500 meters.
The expected wind configuration will probably set the ash cloud and sulfur dioxide towards the south from the eruptive zone and the most affected area of the island of La Palma will be the southern half, mainly the southwest slope. In addition, this arrangement of the cloud could lead to the arrival of fine ash to the island of El Hierro. The high stability in low layers, together with the weak winds and breezes from the west slope are unfavorable meteorological conditions from the point of view of air quality.
Seismicity continues to be located, mainly, in the same areas as in previous days, which correspond to the area where the seismicity of this volcanic crisis began to be located and some depths between 10 and 15 km. In addition, earthquakes are recorded at depths greater than 20 km. In the last 24 hours, dozens of earthquakes have been located, the largest of them of magnitude 3.6, which has been felt with intensity III-IV. There may be more earthquakes felt by the population that can cause small landslides in sloping areas. In some seismic stations it is even possible to record the tremor associated with the lava delta.
The deformations show in the stations far from the eruptive center a slight downward trend in the vertical component and in the nearby stations, stability, and also some pulses related to the eruptive dynamics of this volcano.
The SO2 emissions associated with the volcanic plume continue to register relatively high values and in accordance with the process, reached values of 2,330 tons per day. The diffuse emission of carbon dioxide associated with the 220 km2 of the Cumbre Vieja volcanic ridge, outside the volcano, has reached values of 1,870 tons per day. During yesterday the SO2 values at the Tazacorte, Los Llanos and El Paso stations were gradually reduced to the current values that are below 20 micrograms / m3. In the rest of the island’s stations, the values continue to be low.
Regarding particles smaller than 10 micronsWe are measuring high values in all of the island’s stations, with the daily threshold being exceeded yesterday at the Los Llanos stations; Las Balsas, in Los Sauces, El Pilar and La Grama, in Santa Cruz de La Palma, with Los Llanos station showing the highest daily average. At this moment, a Saharan dust intrusion is taking place that adds to the values of the particles of the eruption.
