09.Subduction-zone megathrust earthquakes: New perspectives from insitu data & laboratory analyses

In the last decade or two, an enormous amount of new findings has been gained about activities and characteristics of seismogenic zones. They include a variety of phenomena along subduction zone megathrusts, ranging from creep to earthquakes including slow earthquakes surrounding the locked zone, high-velocity slip and low frictional strength. In this SPEPS article collection, we invite authors to contribute innovative research or reviews on subduction zone megathrusts, both in presently active ones and onland outcrops. The approaches may include, but are not limited to, results from a wide range of disciplines including observational geodesy and seismology, geological and geophysical studies of present and ancient subduction zones, borehole logging and monitoring, laboratory experiments, and theoretical and numerical modeling.
