We are pleased to inform you that the weekly volcanological part GUAYOTA - Canary Islands of March 4, 2022 is now available. This part reflects the seismo-
volcanic activity registered in the islands from last Friday
February 25 at 00:00 hours until Friday March 3 at 00:00 hours and the
volcanic alert level in the Canary Islands. Currently the
volcanic traffic lights of Tenerife, El Hierro, Lanzarote and Gran Canaria are in GREEN position; therefore, residents and visitors of these islands can develop their activities with absolute normality. Almost three months after the end of the eruption on the island of La Palma, geophysical and geochemical parameters have not yet returned to normal; therefore, its
volcanic traffic light is in YELLOW position. This means residents and visitors must continue to pay attention to communications from civil protection authorities.
Regarding the seismicity, we observe that over the last week the Canary Seismic Network has registered 103 earthquakes of low magnitude whose maximum value has been 2.6 related to an
Earthquake located about 30 km north of the island of Tenerife last Tuesday March 1st. The total seismic energy released has been 2.9 gigajules, which is similar to El Iron Island's electricity demand in about 10 minutes.
The earthquakes are mainly located in the three most
volcanically active areas of the Canary Islands, namely the islands of Tenerife, El Hierro and La Palma. The latter remains a low-magnitude seismicity, much lower than that observed during the 2021 eruption. The Canary Islands are also characterized by moderate tectonic activity; therefore, some earthquakes have also been recorded along some active seismic faults such as the one between Tenerife and Gran Canaria.
Regarding ground deformation, no relevant changes were observed on any island over the last week. With respect to the emission of gases and excluding the areas of La Bombilla and Puerto Naos, where abnormal emissions of carbon dioxide (CO2), continue to be recorded, the Canary Geochemical Network reflects that diffused emission values of
volcanic gases Relatively higher are registered in Tenerife, where we already know that, from 2016, a process of pressurization of the
volcanic-hydrothermal system is registered. We clarify that this process is normal in active
volcanic systems and does not imply the possibility of a
volcanic eruption in the short and medium term.
