Detailed geodetic imaging of earthquake ruptures enhances our understanding physics and associated ground shaking. The 25 April 2015 moment magnitude 7.8 in Gorkha, Nepal was the first large continental megathrust rupture to have occurred beneath a high-rate (5-hertz) Global Positioning System (GPS) network. We used GPS interferometric synthetic aperture radar data model as slip pulse ~20 kilometers width, ~6 seconds duration, with peak sliding velocity 1.1 meters per second, which...
Abstract Many communities and ecosystems around the world rely on mountain snowpacks to provide valuable water resources. An important consideration for resources planning is runoff timing, which can be strongly influenced by physical process of storage within release from seasonal snowpacks. The aim this study present a novel method that combines light detection ranging with ground‐penetrating radar nondestructively estimate spatial distribution bulk liquid content in snowpack during spring...
Abstract The seasonal snowmelt period is a critical component of the hydrologic cycle for many mountainous areas. Changes in timing and rate as result physical flow paths, such longitudinal intra‐snowpack can have strong implications on partitioning meltwater amongst streamflow, groundwater recharge, soil moisture storage. However, paths are highly spatially temporally variable thus difficult to observe. This study utilizes new methods non‐destructively observe spatio‐temporal changes liquid...
