Masaya volcano is noted for long-duration periods of voluminous gas emission.  This February 1982 photo from the NE shows a gas plume pouring from Santiago crater, during the 4th gas emission crisis of the 20th century.  Emission of a very large gas plume had continued without interruption since the fall of 1979.  Remote sensing of SO2 revealed continued high level flux, with a 1500-2000 tons/day average during 1980.  Distribution of the gas plumes by prevailing winds caused widespread crop damage.
