How Do You Predict A Volcano Eruption?
Until recently, volcanic eruptions were feared, but accepted as unavoidable and unpredictable natural phenomena. With improvements in monitoring technology, however, scientists are now usually able warn the public of an eruption before it takes place. If you don’t happen to have a seismograph or correlation spectrometer on hand, don’t worry. Here are some basic indications that a volcano might be about to blow. Look for plumes of smoke or clouds of gas on or around the volcano that aren’t typically there. As magma flows into the chambers beneath a volcano and rises to the surface, it can cause different gases to be released, which geologists keep a close eye on for changes in quantity or composition. Look out for any changes in seismic activity near the volcano. Many volcanoes continuously give off rumbles or tremors, but a sudden increase in the number or strength of these quakes can indicate impending eruption. Take note of strange activity that you may not immediately recognize as a
