The highest diffuse gas emission is on Teide

The Volcanological Institute of the Canary Islands (Involcán) has warned in its weekly report 'Guayota' that the highest diffuse gas emission values ​​are recorded in Tenerife, with a spike in concentrations on Mount Teide.

The highest diffuse gas emission is on Teide

The Volcanological Institute of the Canary Islands (Involcán) has warned in its weekly report 'Guayota' that the highest diffuse gas emission values ​​are recorded in Tenerife, with a spike in concentrations on Mount Teide. The CO2 emission has exceeded the normal or 'background' value set in this report by approximately 7 times.

The Canary Geochemical Network reflects that the diffuse emission values ​​of volcanic gases "relatively higher are recorded in Tenerife", where they recall that, as of 2016, a process of pressurization of the volcanic-hydrothermal system is recorded, clarifying that it is "normal » in active volcanic systems and «does not imply the possibility of a volcanic eruption in the short and medium term».

For its part, the emission of gases is maintained in La Bombilla and Puerto Naos (La Palma), where anomalous emissions of carbon dioxide (CO₂) incompatible with life continue to be recorded.

More than six months after the end of the eruption on the island of La Palma, the geophysical and geochemical parameters have not yet returned to normal, they recall, so the volcanic traffic light is still 'yellow'. This implies that residents and visitors have to continue to be attentive to communications from civil protection authorities.

Over the past week, the Canarian Seismic Network has recorded a total of 97 low-magnitude earthquakes, and a maximum value of 2.1 in an earthquake located between the islands of Tenerife and Gran Canaria that occurred last Friday, June 17 . In addition to earthquakes, last Friday, June 17, the Canarian Seismic Network has recorded a swarm of hybrid events, located around Mount Teide.

In one week, this seismicity has generated 0.75 gigajoules of energy, an amount that would be capable of supplying the electricity demand of the island of El Hierro for 2 minutes.

The earthquakes were located mainly on the islands of Tenerife, El Hierro and La Palma. A low-magnitude seismicity remains in the latter, much lower than the seismicity observed during the 2021 eruption. Some earthquakes have also been recorded along some active seismic faults such as the one between Tenerife and Gran Canaria, assures Involcan.
