Interesting Facts About Earth Volcanoes: Don’t Miss The Greatest Wonder Of The World!

A volcano is a mountain which opens downward to a specific reservoir of molten rock below the earth surface. Unlike many mountains that are pushed up from below, volcanoes are unique vents through which molten rock escapes to the surface of the earth. When pressure from the gases within the molten rock becomes terrific, an eruption occurs. Eruptions can be explosive or quiet. There may be flattened landscapes, lava flows, poisonous gases, and flying ash and rock which can sometimes travel several miles downwind. Due to intense heat, lava flows are extreme fire hazards. Lava flows can destroy everything in their path, but most move gradually enough that people can easily move out of the way.

While not instantly dangerous to many adults, the acidic ash and gas can cause lung damage to minor infants, older adults and to those suffering from acute respiratory illnesses. Volcanic ash can also destroy machinery, including electrical equipment and engines. Ash accumulations that are mixed with water become heavy and can damage roofs. Volcanic ash can affect people several miles away from the cone of a volcano.
The Sideways-directed volcanic explosions called “lateral blasts,” can shoot huge pieces of rock at very great speeds for many miles. These explosions can easily kill by burial, impact or heat. They are known to knock down the whole forests. Volcanic eruptions can be associated with other natural hazards, including mudflows and flash floods, earthquakes, landslides and rockfalls , fire (under special conditions), acid rain, and tsunamis. Active volcanoes in the United States are found majorly in Alaska, Hawaii, and the Pacific Northwest. The danger region around a volcano covers almost a 20-mile radius. However, some dangers may exist 100+ miles from a volcano.
