Two studies showcase new methods for analyzing GRACE data that better match the land surface, producing clearer estimates of mass variations.
Geodetic measurements indicate that Three Sisters Volcano uplifted by almost 300 millimeters in the past 25 years without significant anomalies at the surface.
Applying new technology rooted in quantum mechanics and relativity to terrestrial and space geodesy will sharpen our understanding of how the planet responds to natural and human-induced changes.
A physics-based method estimates the duration of earthquakes’ coseismic phase and can help improve the precision of coseismic slip models and magnitude estimates.
A new method uses Bayesian inference to jointly invert for non-planar fault geometry and spatially variable slip (with associated uncertainties) in earthquake source modeling, based on geodetic data.
Enhancements to the largely invisible framework will enable researchers to investigate pressing questions about our planet’s future.
Kristine M. Larson was awarded the 2020 Charles A. Whitten Medal at the virtual AGU Fall Meeting in December. The medal is for “outstanding achievement in research on the form and dynamics of the Earth and planets.”
Gravity measurements reveal depth and storage conditions of rhyolitic magma reservoirs beneath the Laguna del Maule volcanic field in Chile.
Geodetic observations collected during back-to-back decadal research campaigns have revealed crucial new insights into the start–stop and slow-motion behavior of subduction zones.
New research using continuous GPS data reveals how multiyear precipitation patterns can amplify the effects of hydrological loading on crustal deformation.
