Science of Volcanic Activity Prediction Essay -- Nature Volcanoe Volca

Science of vol crowd outic Activity PredictionSince the dawn of history, volcanoes have been an awe inspiring attribute of the earth that has frightened and intrigued mankind. Volcanoes have taken the lives of over 250,000 people in the last three hundred years and changed the lives of millions of others, but up until of late humans have had very little intellectual of the volcanic processes that calculate an gonorrhea. The advent and implementation of new technologies and scientific methods has allowed us to begin to get across the inner workings of one of natures most powerful forces. Through understanding how volcanoes work, volcanologists hope to accurately predict when an eruption may occur, what the magnitude and subject of eruption will be, and what effect it will have on the environ argona. Accomplishing this daunting task will ensure that in the future when an eruption occurs, the population at risk will be prepared and lives can be saved.Numerous methods are av ailable for monitoring volcanic activity, and scientists typically synthesize data and observations from all methods available in order to accomplish the most comprehensive look at the area being observed. unmatchable frequently used technique is monitoring seismic activity that may indicate flow of magma and gas beneath the surface. As magma at innate temperatures of sometimes over one thousand Degrees Celsius rises through cracks in the Earths crust, the vivid temperature and pressure causes the surrounding rock to crack, as illustrated in the diagram above. This breakable fracture of the surrounding rock often causes earthquakes or vibrations called tremors. Usually these earthquakes are of magnitude 2, 3 or lower, and seismographs monitor these quakes so that t... ...ray, J. Monitoring busy Volcanoes.
