Session Description
Earthquake Geology is crucial to understanding fault dynamics, crustal deformation, and morphotectonics of seismogenic mountain ranges. Characterizing Himalayan active faults remains challenging due to infrequent great earthquakes, insufficient paleo- earthquake knowledge, and prolonged erosion/sedimentation precluding cumulative scarps, making examining the earthquake behavior over multiple seismic cycles strenuous. Techniques like characterizing the inter-, co-, and post-seismic periods, revealing concealed structures, etc., contribute to a more thorough grasp of the tectonic processes from seconds to decadal scales. Thus, an integrated approach to paleoseismology, seismology, geodesy, and geophysics helps identify active structures and understand a fault'sslipbehavior, which is essential for constraining possible earthquakes' magnitude and recurrence. This session invites a broad range of interdisciplinary contributions addressing recent or past intracontinental earthquakes and modeling of active faults, which would enhance our understanding of fault mechanics and
the earthquake cycle.
