Volcanoes

Acid Rain

Gas emissions from volcanoes eruptions contributes greatly to the formation of acid rain. This is because of the deposition of acidic components in rain, snow, dew, or dry particles. Sulphur Dioxide is the main contributer from eruptions of volcanoes.

Ash Fall

Heavy ash fall crushes building and covers fields, electronics, and machinery. The wind may carry the ash to another area, causing problems for the people in the area where the ash is carried to. Volcanic ash, while bringing destruction in the short term, can enrich farming soils and bring in harvest to the farmers, e.g Indonesia.

Volcanic Gases

Even when a volcano is not erupting, it gives out gases from fumaroles, cracks or openings from the ground. Most of these gases is water vapor combined with carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrogen, and fluorine to produce harmful gases such as acid rain. Damages to forests and soils, animals, plants, human health are prominent,as a result of this dry acid deposition, along with visibility problems. Extra carbon dioxide in the air will result in animal and human deaths. The fluorine will poison wildlife and contaminate water supplies.

Landslides

Landslides are very common with volcanoes. Terrible shaking of an eruption causes the loose debris on the side of the mountain to fall down its steep flank quickly. However, debris avalanches may also be caused by earthquakes or heavy rainfall. Massive landslides causes surrounding cities and the obliteration of wildlife and such to be buried.

Lahars

Of all the effects of volcanoes, mudflows or lahars are the deadliest. Debris flows of mud, rock, and water travel down the flank and into valleys and streams at velocities of 20 mph to 40 mph. Some extreme cases have lahars with a consistency of wet concrete flowing up to 50 miles. Lahars destroy houses, trees, and huge boulders like a flood.
