A new wash from the La Palma volcano devastates the Las Manchas cemetery

Regarding the affected infrastructuresAccording to the Cadastre data, there are already 1,484 buildings, of which 1,195 (+2) for residential use, 160 (+1) for industrial use, 67 for industrial use, 34 for leisure and hospitality, 13 for public use and other uses are 15.

According to the total area of ​​affected crops The 340.59 hectares have already been exceeded, of which 211.19 (+4.99) are banana trees, 60.02 (+0.01) are vineyards and 26.4 are avocado.

Eruptive process

The fissure eruption continues to show a strombolian mechanism, that is, a mechanism of a mixed nature, with phases of variable explosiveness that produce pyroclastic deposits and effusive phases that simultaneously produce lava flows. The eruptive process shows episodes of increase and decrease in strombolian activity, as well as pulses with phreatomagmatic activity.

Strombolian activity persists, with pyroclastic and / or ash emission pulses. There is an increase in the emission rate, with an increase in the ramification of lava channels and overflows that affect the same area of ​​yesterday between 4 and 7, and surrounding the Northeast area of ​​the Todoque Mountain. Around 09:00 hours, an episode of sudden increase in lava emission at the main effusive emission point. Around 11:00 a.m., from some of the easternmost broadcasting points, a cast of lava flowing to the Southwest, occupying new territory.

Currently, several emission centers with variable activity (both pyroclasts and gases, as well as lava) are still active as the configuration of the eruptive zone changes. The appearance of new emission centers around the main cone, within the exclusion zone, is not ruled out.

Weather forecast

On the surface wind with an East component with a breeze regime on the West slope. Predominance of component O winds from 1,500 to 5,000 meters. The ash cloud and sulfur dioxide (SO2) are expected to continue to be disposed towards the East – Northeast from the eruptive focus, assuming an unfavorable scenario for aeronautical operations, mainly for La Palma airport. As of Saturday, the wind is forecast to be E component from surface to mid-level troposphere. The expected change in wind direction will represent a favorable scenario for the operation of the airport of The Palm. As expected, persistent and locally heavy rainfall is being recorded on the eastern slope of La Palma. For tomorrow, Friday, heavy to very heavy rains will continue, which could be accompanied by storms. Adverse Weather Phenomena warnings have been issued through the Aemet.


Seismicity at intermediate depths continues at low levels and continues to be located in the same areas. At depths greater than 20 kilometers, seismicity has decreased. The maximum magnitude has been 3.9 mbLg of an event registered today, at 07:53, direction IV (EMS), at a depth of 11 kilometers. Tremor remains low. The current level of seismicity continues to indicate that it is possible that more felt earthquakes may occur, being able to reach intensities V-VI (on the EMS intensity scale) and causing small landslides in sloping areas.

Regarding deformation, there are no significant signs associated with the current eruptive process.

Emission of gases

The SO2 emission, associated with the volcanic plume of the current eruptive process underway (visible emanations of volcanic gases), recorded through the use of remote optical sensors type miniDOAS during yesterday continues to be High (Extremely High> 50,000 tons per day; Very High between 30,000 and 49,999 tons per day; HIGH between 1,000 and 29,999 tons per day; MEDIUM between 100 and 999 tons per day; LOW between 50 and 99 tons per day; Very Low between 5 and 49 tons per day and Extremely Low <5 tons per day). On the other hand, the analysis of satellite images reflects a downward trend since last September 23, when an extremely high SO2 emission was recorded.

In the case of the diffuse emission of carbon dioxide (CO2), associated with the 220 km2 of the Cumbre Vieja volcanic ridge (non-visible emissions of volcanic gases), it continues to register values ​​above the average of the background levels and during yesterday the emission was 5 times the average of the background levels (5xB). These diffuse fumes do not represent a danger to people, unless accumulations of CO2 form in poorly ventilated depressions, displacing oxygen from the air and generating anoxic environments. At the Los Llanos de Aridane station (LP10) a slight magmatic-hydrothermal fraction continues to be recorded in the carbon dioxide (CO2) of the soil atmosphere, while this is lower at the Fuencaliente station (LP08). All these geochemical observations are consistent with the current eruptive process.

Air quality

In the early morning of the 23rd to the 24th, the air quality due to sulfur dioxide (SO2), a pollutant associated with the eruptive process, reached unfavorable levels at the El Paso and Los Llanos de Aridane stations, exceeding the hourly limit value ( set at 350 μg / m³) in El Paso and two in Los Llanos de Aridane, the values ​​were subsequently reduced and remained between good and reasonably good all day yesterday, as in the rest of the stations, however due to At the early morning high values, the daily limit value (established at 125 μg / m³) in Los Llanos de Aridane was exceeded. During this morning there has been an increase in the early hours in the values ​​registered, reaching a reasonably good level in El Paso and Puntagorda, and regular in Los Llanos de Aridane. In the rest of the stations the levels remain good.

PM10 particles

With regard to particles smaller than 10 microns (PM10), yesterday high values ​​were recorded in Los Llanos de Aridane in the middle of the morning and early at night, which meant that the daily threshold was exceeded (established at 50 μg / m³). On the east side of the island, levels have improved, with all stations at levels between good and reasonably good. During this morning, the 24-hour moving averages remain at good or reasonably good levels in all the stations, except in Los Llanos de Aridane, which is at a regular level. Therefore, and as a precautionary measure, in the area of ​​Los Llanos de Aridane, Tazacorte, El Paso, Tijarafe and Puntagorda, for risk groups and sensitive populations, consider reducing energetic and / or prolonged activities abroad.
