Streams, springs, and volcanic lakes for volcano monitoring
Steven E. Ingebritsen, Shaul Hurwitz
2024, Scientific Investigations Report 2024-5062-F
IntroductionVolcanic unrest can trigger appreciable change to surface waters such as streams, springs, and volcanic lakes. Magma degassing produces gases and soluble salts that are absorbed into groundwater that feeds streams and lakes. As magma ascends, the amount of heat and degassing will increase, and so will any related geochemical...
