Majority of the 250 residents of the volcanic Italian island Vulcano are forced to evacuate on Thursday, October 21 due to dangerously high carbon dioxide (CO2) levels in the air. Based on the Italian National Institute for Geophysics and Volcanology (INGV), CO2 levels at Vulcano, in the Aeolian archipelago off the north coast of Sicily, have grown from 80 tons to 480 tons, severely reducing the amount of oxygen. As per Lipari Mayor Marco Giorgianni, non-researchers and non-civil protection officers are not allowed to stay in the “red zone”. People can choose to stay in “yellow zones”, but only on the top floors of their homes. Non-resident visitors and tourists are also prohibited from visiting the island for a month. According to the INGV’s Palermo and Catania-Etneo Observatory website, four geochemical stations that detect CO2 from the soil are currently running. Additionally, the observatory built seven new seismic stations: six on Vulcano and one on Lipari. A high-definition thermal camera has also been installed to monitor soil temperature.
