Week 5 -Volcanoes

 

Volcanoes 

    There is over 18 holocene volcanoes located in France. Holocene volcanoes are volcanoes that were active at least in the last 11,700 years. These type of volcanoes can be either a volcano that is not erupting right now (dormant) or could erupt in the future (active). There are active volcanoes in French territory in the Pacific and Indian Ocean. Eruptions may occur such as possibly 173 volcanoes in the next 350 years although it wont be much of an impact. Volcanoes can spew hot, lava, ash, dangerous gases, and rocks that can be destructive. The blast itself from the volcano can kill many people. Volcanoes can also cause additional warnings to health such as floods, power outages, mudslides, wildfires, and drinking water contamination.

    The most effective volcano in France was Mount Pelée on May 8 of 1902 which had a death toll of more than 29,000 people and destroyed the city of Saint Pierre and was considered the deadliest eruption of the 20th century. The most recent eruption was in 1932. Mount Pelée is a stratovolcano which is built up by many layers of hardened lava and ash. Physically, they are ore cone-shaped volcanoes.

If a volcano were to erupt, everything depends on the person's location. People might be asked to shelter in place or to evacuate depending on how close you are to the volcano. If you are located in a town or city and there’s signs, you must follow them and take the evacuation routes. If located in a lahar hazard zone, get to higher ground then shelter in place. Emergency procedures are provided and updates on the eruption. That is if an eruption is underway. If you are located near or on the volcano during an eruption, stay off valley floors because of volcanic mudflows. Although definitely move away from hazard zones as soon as possible because you will be exposed to falling ash, volcanic rocks, lava flows, lahars, toxic gases, avalanches of hot rock and gas. The ash particles can be small enough to be inhaled deeply into the lungs. Listen carefully to  broadcasts and radios or sirens.
