Abstract
The paper proposes a method for searching for the M2 tidal harmonic in seismicity, based on the construction of time series of conditional accumulated seismic energy (CASE) with a given discretization and their adaptive spectral analysis. The preliminary results of testing this method on seismic observations throughout the territory of California for the period 1983–2012 are presented. For the first time, the fundamental harmonic of the lunar tide M2 was reliably identified in weak seismicity variations at a significance level above 5σ in the range of energy classes 5–9. Confinement of areas with significant M2 amplitudes to the San Andreas Fault and its branches was established.
期刊介绍：
Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
