Rome, October 1, 2021 – The Civil Protection Department has ordered the transition to the level of ‘yellow’ warning for the island of Vulcano, “in accordance with the civil protection structure of the Sicilian region and with the unanimous opinion of the Commission for the prediction and prevention of major risks”. In fact, the department has ruled that “the significant variations of different parameters of volcanic monitoring, detected in recent weeks by the NGV and the Institute for Electromagnetic Research of the Environment Cnr-Irea, require some additional measures and initiatives for the management of the risk on the island”.
In particular, explains the Civil Defense, “the yellow alert level determines, among other things, the amplification of monitoring and surveillance volcanic (also with the possible involvement of other centers of expertise besides Ingv and Cnr-Irea that usually deal with it), a constant information link between the scientific community and the other components and operational structures of the National Civil Protection Service, ‘ updating plans for civil defense, a widespread activity of information for the inhabitants of the island and for tourists, with specific reference to increasing the level of risk. The civil protection structures of the Sicilian Regional Authority and the Municipality of Lipari have already been activated in this sense to take all necessary initiatives”.
“Thanks to the efficient integration of the scientific community into the civil protection system – he explains Fabrizio Curcio, head of the department – today we can count on volcanic monitoring and surveillance systems that allow us to closely monitor the evolution of the activity of our active volcanoes. And that’s what we do on Vulcan. At the yellow alert level (which can be followed by orange and red or the return to the regular green level) it is very important that there is full awareness of the risk, without alarmism, but with great responsibility”.
The island of Vulcano usually already presents a widespread risk situation for the population mainly associated with fumaroles rich in gas and with high temperatures, but at this stage – the ministry recalls – “they can intensify and extend over larger areas and therefore the danger is greater. Any further significant change of the situation will be communicated immediately”.
Mayor Lipari: “Attention”
“In the crater of Vulcano i values I am outside the norm only in the upper part. The experts of the high-risk committee assess the yellow area. “This was reported by the mayor of Lipari Marco Giorgiann, after he attended the meeting with the volcanologists of Ingv and Civil Defense.” The values - explained the mayor – care the gas leakage, temperature and fumarolic activity. It is important that in the lower part of the volcano and in the other parts of the island that the values evaluated by the sensors are checked, they are all normal. The Major Risks Commission is waiting to determine whether it should move from the normality that existed in the crater’s activity to a yellow zone. It’s not a warning, it’s a attention. On the other hand, it is well known that you live on a volcanic island.”
The “activity of the crater is concentrated in the” fossa. A major eruptive cycle began in 1727 and in 1739 with the rhythmic pouring of ‘Pietre Cotte’, Vulcano’s most recent lavish activity. During the successive 150 years there was sporadic explosive activity, culminating in theVulcan’s last eruption, which took place between August 2, 1888 and March 22 1890. This eruption is the type of event that led to the introduction of the term “Vulcan” activity, characterized by distinct, very strong explosions, ejecting fragments of lava in a near-solid state. Since the end of the last eruption, Vulcano has been in a state of eruptive calm, but this ‘sleep’ is sometimes disrupted by seismicity crises and increases in fumarolic emissions and temperatures, the most recent occurring in 1985″.
