Mexico volcano erupts again! What are the hazards of volcanic eruptions?

In the early morning of the 25th local time, Mexico's bobocatepet volcano erupted again. The eruption was violent, with a large amount of volcanic ash soaring into the sky, accompanied by the eruption of magma fragments. Bobocatepet volcano is located about 90 kilometers southeast of Mexico City, the capital of Mexico, with an altitude of more than 5400 meters. It is one of the most active volcanoes in the world. In March this year, popocatepet volcano was active frequently, and Mexican officials upgraded the early warning level to yellow Level 3. So, what are the hazards of volcanic eruptions?

Hazards caused by volcanic eruption:

1. Impact on life

Volcanic ash is different from soot. It is hard small particles and insoluble in water. Inhalation of volcanic ash can cause damage to the respiratory tract and lungs of people and animals, leading to respiratory diseases. Volcanic ash will affect mechanical equipment and damage vehicles such as cars and aircraft. In addition, the eruption of larger volcanoes will also cause a large number of casualties.

2. Impact on the environment

A large amount of volcanic ash emitted by volcanic eruption combined with rainstorm to form debris flow, which can wash away roads and bridges, inundate nearby villages and cities, and make countless people homeless. Mud formed by mud and rock debris can flood the whole city like a flood.

3. Impact on climate

A large amount of volcanic ash and volcanic gas emitted during volcanic eruption have a great impact on the climate. The toxic gases from volcanic eruptions contain sulfur and chlorine, which can form acid rain. When the volcano erupts, volcanic ash and volcanic gas are sprayed into the air, and they will be scattered everywhere with the wind. These volcanic materials will block the sun, reduce the temperature, reduce the yield of crops, and even lead to the extinction of species.
