Why volcano fumes are dangerous to humans

Have you heard of Mount Vesuvius and the City of Pompeii? Try searching on the internet. Here is one of the Pompeii City documentation videos on Youtube.

Once upon a time in 79 (79 AD) Mount Vesuvius in Italy erupted violently. The energy of the eruption destroyed everything at the foot of the mountain. But it is reportedly not only the hot pyroclastic flow which killed many of the population of Pompeii. Any other. And that is a very hot gas.

When younger siblings sit near the fireplace while camping or are in the kitchen when mom or dad cooks, then they will definitely feel hot air when approaching the stove. That's more or less the atmosphere when the mountain erupted. The difference is that heat can hit us hundreds of miles per hour speed.

On another occasion, on August 21, 1986, a volcanic gas eruption occurred at Lake Nyos in northern Cameroon (Africa). Lake Nyos is a volcanic crater lake. On that day, the bottom of Lake Nyos emitted gas. None of the residents of the surrounding villages were aware, because it happened at night when they slept. When this natural disaster was discovered, the death toll had reached more than 1700 inhabitants. The victims have sucked air that contains carbon dioxide very much (CO2).

When a volcano erupts, it is not only lava and pyroclastic material that vomits, but also hot and toxic gas. Toxic gases which include carbon dioxide (CO2), carbon monoxide (CO), SO2 (sulfur dioxide), and HCl (Hydrochloric acid), hydrogen fluoride (HF), hydrogen sulfide (H2S), ammonia (NH3), and methane (CH4) out of the crater then mixes with the surrounding air. The air also has a high level of acidity (pH).

In addition to making the body limp, if sucked continuously it can cause irritation to human organs. In the process of irritation, cells and organ tissues are likely to be damaged and melted.

Have you ever seen a chicken meat experiment dipped in acidic liquid?

In addition to containing the above chemicals, the gas that comes out when a volcano erupts also contains very small (micro) glass crystal flakes. Glass crystals can only be seen using a microscope (see photo below). The sharp jagged edges can certainly injure human respiratory organs when inhaled.

Volcanic ash particles are seen using an Electron Scan Microscope (SEM) Similarly, brothers and sisters, the danger of volcanic gas that comes out when a volcano erupts. If you live around an active volcano, always make sure you keep a mask at home. Immediately wear the mask when disaster strikes. Follow the father and mother to evacuate immediately. At this time the notification of a disaster or symptoms of a volcanic eruption will be broadcast quickly by radio and television news stations. May we all be avoided from the disaster.
