Images of the new emission focus – INVOLVE
SANTA CRUZ DE TENERIFE, Oct 2 (EUROPA PRESS) –
The Cumbre Vieja volcano, which will be two weeks after its eruption on Sunday, has already affected a total of 1,005 buildings, of which 880 are destroyed and 105 are damaged or at risk of being destroyed, and it is not ruled out that in today there are new homes affected. In addition, there are 28.3 kilometers of unused roads and 201 people are still housed in the Hotel Princess, in Fuencaliente.
Likewise, the lava flows have destroyed today the last irrigation connection that was in the El Remo area, which has caused a significant focus of white smoke that came from the surroundings, as a result of the lava entering contact with water.
The Cabildo de La Palma has reported that the fruit cutting operation continues in El Remo, Charco Verde, Puerto Naos and Tazacorte. The access of the cut trucks to the area will be through the Fuencaliente highway and the Las Martelas straight will be the meeting point to cut north of the La Laguna mountain. The cutting operation is organized in three shifts (08:00, 11:00 and 14:00). Please be at the departure point half an hour before. At this time, only farmers can irrigate with their own water tanks.
At a press conference, the technical director of Pevolca, Miguel Ángel Morcuende, who recalled that we are facing an eruptive process in which there is an associated seismicity, among other things, because the caldera that contains the magma and causes holes, which It does is reorder itself and in the end it ends up 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 not to provide more clothes or blankets, since they are no longer necessary as there are enough, and indicated that the transport of these items creates a problem because then you have to do the triage and, above all, they take up a lot of space on the boats.
Carmen López, national responsible for volcanic surveillance of the IGN, has pointed out that the fissure 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 to the west parallel to the main stream and has reached the end of the Los Campitos road at 0900 hours, establishing subsequent lateral contact with the previous streams. In addition, several active centers are observed 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.
Carmen López pointed out that the fajana is at a distance greater than 540 meters from the coastline and 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 are concentrated 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., a small ash and gas emission center was opened. 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 ashes of the cone was measured and it is around 4,500 meters.
The expected wind configuration will probably dispose of the ash cloud and sulfur dioxide to 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 at 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 line with the process, reaching 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 microns, we 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 the Los Llanos station having the highest daily average. At this time there is an intrusion of Saharan dust that adds to the values of the particles of the eruption.
