Staging of Acoustic Emission in Laboratory Modeling of Tidal Effects in Seismicity

摘要

Experiments on sandstone destruction were carried out in order to reproduce the influence of Earth tide on seismicity under controlled laboratory conditions. The discovery of staging in acoustic response of destruction of a specimen to an external weak periodic effect is decided as the main result of the experiments. Moreover, the different stages are related to the different conditions of the specimen during the destruction process.
