Volcanologists that monitor gases often use a correlation spectrometer (COSPEC) that measures sulfur dioxide (SO2) in plumes rising out of volcanic craters. An increase in SO2 may indicate an increase in magma near the Earth's surface. ... Some volcanologists are using satellites to monitor active volcanoes.
