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.Continue Reading
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.Learn more about Volcanoes
Examples of cinder cone volcanoes are Kula and Karapinar in Turkey; Taal Volcano in the Philippines; Hverfjall in Iceland; El Jorullo, Parícutin and Pinacate Peaks in Mexico; Mounts Leura, Fox and Elephant in Australia; Royal Society Volcano in Antarctica; Manda-Inakir on the Ethiopia-Djibouti border and Barren Island in the Andaman Islands. The United States hosts over 100 cinder cones, mainly in western states and Hawaii.Full Answer >
Some of the advantages that volcanoes provide include the creation of new land, mineral deposits and beautiful landscapes that generate tourism. Active volcanoes actively cool the Earth, as their emissions remove heat from the planet's interior. Volcanic activity also helped produce the Earth's atmosphere and oceans in the past.Full Answer >
Including the volcanoes themselves, the major landforms volcanoes create include shield volcanoes, stratovolcanoes or composite volcanoes, maars, cinder or tephra cones, volcanic or lava domes, craters, calderas, geysers, hot springs, resurgent domes, flood basalts and plateau basalts. Many of these landforms have significant impacts on ecosystems, according to Tulane University.Full Answer >
Active volcanoes are those that have erupted recently or regularly erupt, and inactive volcanoes are those that have not erupted for a long time. The exact time distinction between active and inactive volcanoes differs between experts.Full Answer >
