Abstract
AbstractLeveraging a cloud‐based interferometric synthetic aperture radar time‐series processing framework, we map the surface deformation along the western and central Aleutian volcanoes from 2015 to 2021. The observed crustal deformation from more than 15 volcanoes is attributed to a wide range of magmatic or tectonic processes, for example, magma accumulation in the magmatic reservoir, steady cooling or degassing of magma or hydrothermal systems, and faulting. More vigorous magmatism in the central Aleutian is noticed and appears to be related to higher magma production rates or higher magma ascent rates as a result of oblique subduction. New deformation patterns never observed in previous studies are detected and modeled at Tanaga, Great Sitkin and Yunaska. This study showcases the cloud‐processing capability to generate interferograms at scale and processing tools to analyze these time series over large, tectonically active areas.
