</span><span style="font-size:10pt;font-family:Arial,sans-serif">The
processes leading to intraplate earthquakes and creating zones of historical
seismicity in eastern and central North America (such as New Madrid, central
Virginia, eastern Tennessee, Charleston, Western Quebec, and Charlevoix) are poorly
understood. The region has major population centers with infrastructure that is
at risk from infrequent but consequential earthquakes. The 2011 Mineral,
Virginia, earthquake caused significant damage from central Virginia to the
National Capital Region, was felt over much of the eastern U.S., and energized
research and interest in earthquake processes, hazards, and preparedness along
the Eastern Seaboard. Technological advancements (e.g., in geophysical imaging
and modeling, LiDAR, and OSL dating), increased seismic instrumentation
associated with EarthScope’s USArray, NELE, OIINK, SESAME, SUGAR and focused
studies of the Eastern North American Margin under GeoPRISMS offer exciting
research opportunities. We welcome contributions seeking a better understanding
of earthquake occurrence and impacts in any geoscience or engineering
discipline, including but not limited to seismology, structural geology and
tectonics, geomorphology, geodynamics, paleoseismology, geochronology,
geophysical imaging, hydrology, and engineering.<span style="background-image:initial;background-repeat:initial"></span></span></p>
