‘Lab-Scale Seismology’: Ultrasonic Characterization in Rock Mechanics
Session ID#: 78806
Session Description:
Ultrasonic characterization is becoming an integrated part of rock mechanics laboratory settings, to probe and infer the properties of rocks, granular media and geomaterials in general. Such experiments are typically conducted in an active fashion with transmitters and receivers, or in a passive Acoustic Emission (AE) mode. Multi-sensor configurations as well as continuous monitoring are providing new opportunities for refined observations, for instance through imaging procedures or machine learning approaches. Despite these improvements, interpreting the data in light of physico-chemical mechanisms at play is still a challenge. Furthermore, the question remains as to how scalable the ultrasonic observations are and whether they can explain the processes at field-scale. In this session, we invite novel contributions from a broad range of applications (earthquake physics, geothermal or oil/gas energy, volcanology, landslides, and others) that tackles some of the challenges aforementioned, whether it be experimental, numerical or theoretical (or combinations of these).
