Hundreds of people on the island of Pulcano, north of Sicily, are being told that they will not be able to stay overnight due to the volcanic eruptions.
From Monday, about 300 people will have access to alternative accommodation from 11 a.m. to 6 p.m.
And the island, which gave its name to the volcanoes, will be out of service for tourists for a month.
Authorities have declared a state of emergency and a state of emergency, and the alert has risen from “yellow” to “orange”.
This is to bring various measures designed to protect the population in the event of a volcanic eruption or additional gas emissions.
Experts also say that the accumulation of gas can reduce the amount of oxygen in the air, cause breathing problems and even fatal injuries.
Extreme levels of natural gas have been found in parts of Puerto de Levante, one of the island’s most famous hot tubs.
The mayor warned that people could suffer from high levels of carbon dioxide at night.
The word “volcano” comes from the name of the island, which in turn comes from the Roman fire god Pulkan.
Pulkano is the southernmost of the Ilian Islands. It has an active volcano (also called fosa) that has been reported from time immemorial.
Many residents are choosing to stay with friends or family or move to another part of the island.
Officials say they will contribute to the cost of hotel accommodation.
Carbohydrates (CO2) have an odorless and high content that can lead to shortness of breath.
It is very dangerous to sulfur dioxide (SO2) or other acid gases (such as hydrogen chloride), which can be easily detected by bad smells and discomfort in the upper respiratory tract or eyes.
Last month, Stephania Lombardo, a resident of Puerto Levante, told the Italian media:
“They told me it was just a panic attack, and the doctors confirmed that the cause of the illness was breathing gas from the well.”
The last volcanic eruption on the island took place between 1888 and 1890.
