Q:

What damage do volcanoes cause?

A:

Quick Answer

Volcanoes cause physical damage to structures and buildings, wildlife, local vegetation and the atmosphere, as well as posing health risks. Residences within the vicinity of a volcanic eruption often receive timely notice before an eruption occurs. This reduces the likelihood of danger to humans.

Full Answer

Scientific advancements in vulcanology have led scientists to be able to discover signs that indicate when a volcano is about to erupt. This allows the scientists to provide adequate notice to civilians before an eruption occurs, minimizing tragedy to humans.

Even when humans evacuate, however, damage to structures and buildings can occur. Volcanic eruptions throw large amounts of ash. When this ash descends and collects on the rooftops of buildings, the likelihood of the roofs collapsing increases. Because this ash is comprised of fine glass particles and is toxic, when it is breathed in, humans and animals in the immediate vicinity often experience respiratory problems.

Lava flowing from the center of the volcano causes a fire danger to wildlife and plants in the area, with the effects often felt for many miles around. Lava and fallen ash also destroy plant life by smothering it. Volcanic eruptions are also sometimes responsible for triggering tsunamis and electrical storms within areas surrounding the eruption.

  • Q:

    What are the effects of a volcano?

    A:

    Volcanoes have several effects on plants, animals and people and can negatively impact civilization because homes, fields, roads and buildings get damaged with ash and other debris. The ash can become so heavy that homes collapse. Volcano ash positively impacts human life by leaving the soil rich in nutrients. The gases released from the volcano can cause respiratory issues in those unable to evacuate from the region.

  • Q:

    How do cinder-cone volcanoes erupt?

    A:

    Cinder-cone volcanoes, properly called scoria volcanoes, erupt when expanding gas bubbles drive lava to the volcano's surface. Because of this pressure, the lava fountains are usually very high and vertical. By the time the erupted material lands, it is already cool.
