Although on other occasions the ash had been displaced to this area by the wind, this time completely covers the entire orography of that area in the north of the island of La Palma.

With daylight they can be seen through the images offered by the webcams installed in the astrophysical complex, how the ash covers the domes and the rest of the facilities.

In the municipalities of Tijarafe, Fat tip and Garafía, the ash completely covers the landscape, as well as houses and roads. “It is a very fine ash that had never reached here in such a copious way before,” the owner of a bar in Tijarafe, a municipality closest to the city, explains to EFE. Aridane Valley.

But the amount of ash is also important much further north, in Garafía, where neighborhoods such as Cueva de Agua or Santo Domingo, on the north coast, have dawned covered in black.

In Puntagorda a neighbor has pointed out that “the air quality does not seem entirely good, there is a strange smell and the town woke up with a thick layer of smoke, it is necessary to wear a mask at least at this time”, has indicated.

In this sense, according to the website of the Cabildo de La Palma, in which the air quality index data of the different stations distributed throughout the island geography is offered, the Puntagorda station has measured 53.11 ug / m3 of PM-10 particulate matter measured at eight in the morning this Sunday.

This measure is far from the 20 ug / m3 that this parameter of suspended particles considers as good.

According to him Pevolca, volcanic ash is any fine-grained material that is less than 2 millimeters in diameter. It is rock that has exploded and has been shattered by steam inside the volcano. The wind disperses the ashes in different directions and speeds.

About 27 earthquakes recorded overnight

The 24-hour monitoring volcanic surveillance network of the National Geographic Institute (IGN) has located a total of 27 earthquakes associated with the eruption of the Cumbre Vieja volcano on the island of La Palma during the night, seven of them with magnitudes greater than 3.0 (mbLg).

The maximum magnitude recorded was 3.3 (mbLg) corresponding to the earthquake located southwest of the municipality of Villa de Mazo at 04.54 hours. With intensity IV EMS and a depth of 35 km, not being felt in principle by the population.

Yesterday 105 earthquakes were located and the magnitude ceiling of the entire seismic series was reached that began on September 11 with an earthquake of magnitude 5.0 mbLg that was felt on the island of La Palma with an intensity IV-V. It was also felt in El Hierro, La Gomera and the north of Tenerife.
