Seismo-Microplasticity phenomenon in the rocks
The seismic records of borehole-to-borehole measurements on frequency of 200 Hz in the microstrain range have been analysed. Microplasticity manifestations caused by seismic wave are detected on seismic records. It is the ladder-like stepwise change in amplitude course in some parts of the seismic trace. The step duration (time plateau) presents the amplitudedependent time delay that shifts the arrival time and protracts pulse front. The microplastic process occurs owing to the anomalousdoi:10.4236/ns.2010.23025 fatcat:mwkbonlhbrcxzn3bfuvkfrsp7y
