Characterization and interpretation of volcanic activity at Karymsky Volcano, Kamchatka, Russia, using observations of infrasound, volcanic emissions, and thermal imagery

Research at Karymsky Volcano, Kamchatka, reveals distinct infrasound signals associated with four types of volcanic activity: ash explosions, pulsatory degassing, gas jetting, and explosive eruptions. These findings suggest that infrasound can be a reliable tool for remotely monitoring volcanic behavior. The study also indicates that sulfur dioxide (SO2) emissions are continuous but variable, while ash emissions occur intermittently during specific activities. Changes in conduit permeability, potentially linked to magma supply from shallow-crustal storage regions, appear to trigger ash explosions and explosive eruptions. This work advances the understanding of volcanic processes and their monitoring using multiparameter data, including infrasound, thermal imagery, and gas emissions.
