The Alaska-Aleutian subduction zone is one of the most seismically and volcanically active plate boundaries in the world. Over the past decade, it has ruptured in several large interplate and intraplate earthquakes and produced notable volcanic eruptions and non-eruptive activity. It exhibits profound along-strike variations in geodynamics, lithospheric configuration, locking, rupture history of the megathrust and other fault systems, slow-slip events, and magmatic processes. The Alaska-Aleutian subduction zone is thus an excellent place to address fundamental questions regarding subduction zone processes and associated earthquake and volcanic activity. The availability of new geophysical datasets onland and offshore and the occurrence of a series of recent, well-characterized large earthquakes in the Alaska-Aleutian subduction zone have enabled a plethora of new results and insights into subduction processes. We invite a wide spectrum of contributions that focus on the Alaska-Aleutian subduction zone, including investigations utilizing newly available geophysical imaging and monitoring datasets, paleoseismology and geological studies and numerical and experimental studies.
