The volcanic area of ​​Fagradalsfjall was closed on September 12 for security reasons, due to bad weather conditions in the area. (Lögreglan á Suðurnesjum / Police duSuðurnes)

Despite these poor conditions, the tremor shows continued activity.

But the Reykjanes Peninsula isn't the only part of Iceland where there's activity. Seven volcanic systems in Iceland are now on the rise, according to geophysicist Páll Einarsson.

The most active systems: Grímsvötn and Hekla, Bárðarbunga, Öræfajökull, and Askja.

"The most improbable must not be forgotten either. These are the Snaefellsnes volcanic systems. It turns out that exactly one of them showed unequivocal signs of increasing activity and that is the Snaefellsnes system. Ljósufjalla ", explains Páll Einarsson. Between Berserkjahraun and Grábrókur, a short distance west of Langavatn. There have been a number of earthquakes since May ... however, an eruption is not expected at this time: "There is a certain rule of thumb though. If a volcano has not entered erupting for a long time, the period leading up to the eruption also seems long. " he added.

Taal - Summary of activity on 13.09.2021 - Doc. Phivolcs

In the past 24 hours, the Taal Volcano Network has recorded 9 volcanic earthquakes, including 4 lasting one to three minutes, 5 low-frequency volcanic earthquakes, and low-level background tremor that has persisted since 7 July 2021. The activity of the main crater was dominated by the rise of hot volcanic fluids in its lake which generated plumes 2,500 meters high which drifted towards the northeast. Sulfur dioxide emissions averaged 5,246 tonnes / day on September 12, 2021. Based on soil deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island started to deflate in April 2021 as the Taal region continues to experience very slow expansion. since 2020.

Alert level 2 (increased unrest) prevails over the Taal volcano.

I send a message disseminated by Frédéric Lavachery, natural son of the famous volcanologist Haroun Tazieff :

 

Four "Haroun Tazieff" associations work on the scientific and cultural heritage of the explorer who paved the way for modern volcanology in the middle of the last century. All the daughters of France Tazieff's desire not to let oblivion bury her husband's work, they need to be supported.

Their coordination is ensured by the oldest of them, the Haroun Tazieff Center for Earth Sciences (CHT) / http://tazieff.fr/edito/, created in 2008 in Arette, in the Pyrénées Atlantiques, an emblematic village from the Tazieff epic. It was formed around Haroun Tazieff's son, Frédéric Lavachery, whom France had asked shortly before his death to help him carry out this project.

The other associations of the project are, in the order of their creation:

- The Pôle Haroun Tazieff en Vivarais-Velay (PHTVV), It took over the educational and research actions of the CHT on the volcanic territory of Haute-Loire and Ardèche.

- The Haroun Tazieff Archives Workshop (AAHT) for the safeguard, inventory and restoration of hundreds of coils shot for 40 years on the active volcanoes of the Globe.

- The Tazieff-Goma International Transdisciplinary Research Unit (URITTAZ-Goma), to train its researchers in Tazieff's work and explore the new horizons of the anthropology of volcanism opened up following the discovery by Frédéric Lavachery, between 2013 and 2015, very probable representations of erupting volcanoes in the prehistoric frescoes of the Chauvet cave, in Ardèche.

 

You can make a strong contribution to the realization of the "general Tazieff project" by disseminating this appeal or joining one or more of the "Tazieff associations" with a single annual subscription of 20 euros. Any payment of contribution greater than 50 euros will make you a "benefactor member" of our associations.
