Tectonic aerosol sensing by lidar as a new technique for Earth’s crust deformation monitoring

A new-generation eye-safe lidar has been developed for tectonic aerosol sensing. The lidar was installed inside an adit of Baksan Neutrino Observatory to quantify tectonic aerosol fluctuations. As aerosol fluctuations are induced by Earth's crust deformations, a laser strainmeter was used to measure the deformations. A correlation of strainmeter and aerosol lidar signals was observed during low-frequency Earth's crust deformations.
