Electromagnetic Study of Fluid Distribution at the Aleutian-Alaska Subduction Zone
SUBDUCTION TOP TO BOTTOM (ST2B): THE NATURE OF THE SUBDUCTION INTERFACE, EARTHQUAKES, AND THE ROLES OF FLUIDS IV ORAL
tectonophysics | 14 december 2023
Yinchu Li, Samer Naif, Darcy R. Cordell, Kerry Key...
The Aleutian-Alaska subduction zone (AASZ) has been responsible for some of the largest earthquakes recorded in the past century. The AASZ exhibits in...
