FDSN code ZF (2011-2011) Operated by Lamont Doherty Earth Observatory (LDEO), Columbia University
Network name Alaska Langseth Experiment to Understand the megaThrust (ALEUT) Deployment region United States
Start date June 29, 2011 End date July 11, 2011
Short description

The aim of this program is to characterize the megathrust, overriding and downgoing plates, and other fault systems associated with the Alaska-Aleutian subduction zone from the Shumagin gap, across the Semidi segment, to the western end of the Kodiak asperity. To achieve this, we will use multichannel seismic (MCS) reflection and wide-angle reflection/refraction (WARR) data, and relate the reflection and velocity images to the mechanical behavior of the megathrust and other faults based on the history of subduction earthquakes [Davies et al., 1981], historical intraslab and crustal earthquake hypocenter distribution, present-day locking of the plate boundary from GPS data [Fournier and Freymueller, 2007], and other available constraints.
