Earthquakes, Lithospheric Structure, and Dynamics in Stable Continental Region
Damaging earthquakes can occur far from tectonic plate boundaries, where shaking impacts large areas because of low seismic attenuation in bedrock and amplification by sedimentary deposits. Long time intervals between earthquakes, low strain rates, and human development pose challenges to understanding seismic hazard in intraplate areas such as central and eastern North America, northern Europe, central Asia, and Australia. Geophysical imaging, geodynamic modeling, and geologic studies indicate that features inherited from prior tectonism such as intraplate basins, rifts, faults, arches, and domes can be reactivated seismogenically by the modern stress field. This session seeks diverse contributions related to intraplate seismic hazards, lithospheric structure, and dynamics. Studies of recent earthquakes (e.g., 2024 M4.8 Tewksbury, NJ, USA; 2019 M4.9 Le Teil, France) are especially encouraged, as are those of historical seismicity, paleoseismic features, seismic attenuation and ground motions, and constraints on ground shaking ranging from balanced rocks to railroads. We welcome approaches that cross spatial and temporal scales and the disciplinary boundaries between structural geology, geophysics, geochronology, rock physics, and geodynamics.
