摘要

交叉光谱分析应用于俄罗斯科学院（BNO）核研究所巴克桑中微子观测站隧道中近一年的地壳气溶胶辐射激光雷达监测结果。研究发现，激光雷达信号能量的约40%受气象因素的变化控制，即气压（“气压泵送”的影响）和湿度。重要的事实是，信号调制涉及到日月潮汐波М2和О1引起的地壳变形分量。我们为激光雷达作为一种基于地壳气溶胶变化监测局部地震活动的新工具的潜力提供了统计依据。

An Analysis of Variations in the Signal of an Aerosol LIDAR as a Possible Indicator of Local Seismic Activity

Cross-spectral analysis was applied to the results of a nearly one-year LIDAR monitoring of aerosol emanation from the Earth’s crust in the tunnel of the Baksan Neutrino Observatory at the Institute of Nuclear Research, Russian Academy of Sciences (BNO). It was found that ∼40% of LIDAR signal energy is controlled by the variation of meteorological factors, namely, air pressure (the effect of “barometric pumping“) and humidity. The important fact is that the signal modulation involves components in the crustal deformation due to lunisolar tidal waves М2 and О1. We provide a statistical justification for the potential of LIDAR as a new tool in the monitoring of local seismic activity based on crustal aerosol variations.

期刊介绍： Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
