Signs of an Impending Volcanic Eruption •

If you have at least 3 seismometers, and they are strategically placed, you can triangulate on earthquakes to see if they are occurring in a place that indicates perhaps magma movement. When magma moves up into the shallow pluming of a volcano, it takes up space and pushes the surrounding rock outward. !his also causes the surface of the volcano to deform. Some points move upward and any two points will move farther apart. "y using very accurate leveling and distance#measuring techniques, these surface changes can e measured. If the area of active degassing gets larger, if the plants neary die suddenly, if the color of any lakes or ponds neary changes...$any volcanoes have summit lakes through which heat and gases rise to the surface and escape.
