Seismic Moment Tensors and Crustal Stress Fields: Methods of Analysis and Contributions to Geodynamic Modeling

Session ID#: 78313

Session Description:
Seismic moment tensors are fundamental to study the relationship between earthquakes, seismic faults and active tectonics, and several waveform modeling methods allow to estimate them through different approaches and at different scales. Moment tensors are also basic data to evaluate active stress fields, whose spatial distribution and temporal variation provide major insights into earthquake mechanics, tectonic loading, and local/regional seismotectonic settings. 

This session aims to evaluate the state-of-art of methods used for moment tensor estimate, seismic waveform modeling and stress inversion, and to provide an overview of their application at various scales and in different tectonic settings. Contributions by these methods to geodynamic modeling, based on joint use of different kinds of geophysical and geological data, are particularly welcome. The debate is expected to suggest future directions both for theoretical and observational studies.
