Looks like magma could be on the move around all the islands.

Yesterday there were two felt earthquakes La Palma.

La Palma volcano update: digital surface model of new cone
Tue, 8 Feb 2022, 00:57
The volcanology institute INVOLCAN in collaboration with INGV Catania published a preliminary digital surface model (DSM) of the new cone as shown in the picture.
Digital Surface Model (DSM) is a commonly implemented geospatial feature generated with UAV mapping systems and captures both the natural and built/artificial features of the environment.

Post-eruptive Activity Old Summit, #LaPalma (08-02-2022 09:00 UTC)

➡ For the last 7 days, since the last announcement (day 1 at 9:00 UTC) 39 earthquakes have been located on the island of La Palma.
➡ The magnets are between 0.9 and 2.5 (mbLg). 2 of these earthquakes have been felt weakly by the population with intensity II (EMS98).
➡ The location of the hippocenter continues under the central area of Cumbre Vieja in the same areas as in previous days, with 36 earthquakes located at depths between 0 and 15 km. 3 earthquakes with depths between 20 and 34 km have been located during this period.
➡ The network of permanent GNSS stations of the island does not show significant deformations that can be associated with volcanic activity.
➡ The height of the cone is measured getting a value of 1,120 m. above sea level.
🌋 The IGN continues its presence on the island, where the CAVE (Center of Attention and Eruption Surveillance) has been established, maintaining, denensifying and improving the surveillance network.

The January report on volcanic activity in the Canaryas is available

👉 https://bit.ly/3rDsGTm

A total of 442 earthquakes located in the Canary Islands area, with a maximum magnitude of 4.8 mbLg in an Earthquake that occurred on the 18th, located about 140 km south of Fuerteventura, which was felt weak, with intensity II (EMS98), in some towns of the islands from Fuerteventura, Gran Canaria and Tenerife.
On the island of La Palma, 330 earthquakes have been located throughout the month, between magnitude 0.4 and 2.7 (mbLg) and depths between 0 and 35 km associated with post-eruptive activity.

Researchers at the foot of the volcano: "It is active, it has not turned off or died"

A group from the ULPGC led by José Mangas searches for rare earths and analyzes hydrothermal mineralization on the island of La Palma


The degassing of the La Palma volcano continues to set the pace of work for the research groups that continue to work on La Palma. There are areas that are still "very hot" and degassing continues. “We have been able to verify that it is emitting a lot of gases through the mouths and fissures. We have detected sulphur, carbon, chlorine and water” , José Mangas, professor of Geology and member of the Geogar group , attached to the Institute of Oceanography and Global Change (Iocag) of the University of Las Palmas de Gran Canaria (ULPGC) explained yesterday.

The team has been analyzing and sampling hydrothermal mineralizations, which are precisely associated with gases. “Today at various times we have had to put on our masks because the gas detector has gone crazy. You have to be very careful in the degassing process” , explained the scientist.

The volcano "is active, it has neither been extinguished nor is it dead," says Mangas , who likes to name it Cabeza de Vaca-Tajogaite. "There are very hot areas, not like lava, but our boots would stick," he says. The mineral samples will be analyzed in the Geology laboratory of the ULPGC and in the Museum of Natural Sciences of Barcelona. “We want to analyze the minerals associated with these degassings. It is what is studied on Etna or Vesuvius. These minerals are the witnesses of the gases that go into the atmosphere », he added.



In addition, the research group is exploring the outcrops of felsic magmatic rocks to determine the content of rare earths, priority elements for research in the European Union. “We have already shown that there are rare earth resources in Fuerteventura and Gran Canaria . We want to extend the study to La Palma, Tenerife and La Gomera within the Magec-REEsearch project of the ULPGC and La Laguna

“Europe needs rare earths, 95% of which it uses comes from a single supplier, China. They are used for alternative energies, electric cars, magnets, biomedicine,...”, explained Mangas. And although it is difficult to extract in the Canary Islands because most of the outcrops are in coastal areas , there are others that can be exploited.

How to build mortar and concrete with ash
Also on La Palma are members of the Industrial Efficiency, Instrumentation and Protection Systems Research Group (SEIP) of the ULPGC, who, in collaboration with local Canarian companies, are studying possible uses for the volcano's ashes. According to researcher Juan José Santana, the idea is for it to have "a real application and develop a product that reaches the market." They intend, he explained, «to create constructive elements 'in situ', on La Palma, taking advantage of the enormous amount of ashes from the eruption. Among the applications, "the use of construction materials, not only mortar or concrete", stands out. In addition, "it could also serve to remove part of the cement and replace it with ashes and other compounds." The project could also promote local industrial activity
