Аннотация:We report for the first time, as far as we are aware, an asymmetry in the signals of the laser strainmeter at the Baksan Neutrino Observatory (BNO), Elbrus area during the first and second Turkish earthquakes of February 6, 2023, which had nearly identical magnitudes. A correlation has been detected between the signals of the laser strainmeter and the temperature inside the bedrock foundation in the BNO dead-end tunnel, as well as the signal of aerosol lidar during the second magnitude 7.7 earthquake occurring at 10:24 UTC. The radius of the stress zone around the epicenters was estimated as ∼2000 km, which exceeds the distance to the BNO tunnels (~900 km) and thus admits of the variations of stress and strain to be seen in the signals of the laser strainmeter, the thermometer, and the lidar.
