- Аннотация: For the first time, we monitored the Elbrus volcano activity detecting volcanic gases emanatingthrough pores using an unique eye-safe LIDAR system. A highly sensitive eye-safe LIDARsystem was developed for monitoring the fracture-emitted aerosol, which is transported byvolcanic gases inside a hot tunnel near the Elbrus Mountain. The developed LIDAR is based ona diode laser (transmitter, 910 nm, 3 ns, <1 µJ cm−2) and a single-photon avalanche photodiode(detector). From August to October 2019, within the first months of the LIDAR monitoring, wehave detected a two-fold decrease in the fracture-emitted aerosol emanation, while otherparameters in the tunnel remained relatively stable (radon concentration, air temperature andhumidity changed less than by 1%). A significant correlation between the LIDAR signal ofvolcanic aerosol and the Earth’s crust deformation measured by the laser strainmeter locatednearby was found. Based on our preliminary experiments we consider the new LIDAR systemas a sensitive, economical and robust instrument for Earth’s crust deformation and volcanicactivity monitoring and eruption precursor observation.
