Earthquakes in stable continental interiors, far from active plate boundaries, such as in central and eastern North America, northern Europe, western and southern Africa, Australia and parts of Asia, are perhaps the least understood. Nevertheless, advances in intraplate seismicity are being achieved through a variety of approaches. Examples include local- and national-scale seismic monitoring efforts that increase completeness of earthquake catalogs, detection algorithms that identify ever-smaller earthquakes from existing data, imaging of subsurface faults using relocated seismicity, seismic tomography and other geophysical methods, studies that constrain historical slip on such faults, quantification of geodetic, geomorphologic and elevation changes and through improved measurements of local stresses. In parallel with these efforts, ongoing ground motion studies continue to improve our understanding of source, path and site response characteristics unique to intraplate regions. 
 
This session seeks diverse contributions related to intraplate earthquake hazards with goals of improving earthquake catalogs, identifying and characterizing active faults and/or deformation in stable continental interiors, deciphering long- term earthquake histories, statistical analyses of seismicity, assessing potential ground motion impacts, constraining models of kinematics and geodynamic properties and understanding the mechanisms that cause enigmatic intraplate earthquakes. Contributions regarding recent intraplate earthquake sequences are especially welcome.
