At the very dawn of plate tectonics, George Plafker coined the term “megathrust” to convey the massive scale of this most fundamental of all geohazard sources and tectonic features. Megathrust faults produce nearly all of the planet’s seismic moment release and span geologic regimes from unconsolidated sediments to high-grade metamorphic rocks. Plate motion is manifested in many ways, from creep and slow slip events to giant earthquakes and the tsunamis they launch, as well as in the building and destruction of topography. We invite submissions tackling observations, laboratory experiments,  and numerical simulations based in seismology, geodesy, geology, geochemistry, paleoseismology, geomechanics, geomorphology and/or any interdisciplinary combination of these approaches that address frontier questions on megathrust fault systems worldwide.
