A volcano is a mountain opening downwards to the reservoir of molten rock towards the surface of the earth. Volcanoes are made by the accrual of igneous products. As the pressure from gases in the molten rock becomes intense, the eruption takes place. The volcanic eruption can be either quiet or volatile. Its aftermaths include flowing lava, flat landscapes, poisonous gases, and fleeing ashes and rocks.
Threats from volcano
Volcano generates excessive heat. Flowing lava has great fire hazards. It flows to destroy just everything that comes in the path. It can be very acidic, abrasive, gassy, gritty and malodorous. The people suffering from a austere respiratory disease have severe threat. The volcanic ash can harm the machinery, such as electrical equipments and engines. The water mixed with ash can make your roof fall due to its heaviness.
The lateral blasts of volcano can shoot out huge pieces of rock at high speeds for various miles. The volcanic explosions can mar people by its burial and heat. They may knock down the whole forests. The volcanic eruptions can be attached to the other natural hazards, such as mudflows, earthquakes, floods, landslides, rock falls, fire, acid rain and even tsunamis. The danger area of volcano ranges from 20 miles to 100 miles radius and more.
