New Tectonic Plate Model Could Improve Earthquake Risk Assessment
A new model of tectonic plates in New Zealand may identify areas of increased earthquake likelihood.
Enhancing Earthquake Detection from Orbit
A new application of machine learning boosts scientists’ ability to use data from satellite navigation systems to detect and warn of earthquakes.
Models Oversimplify How Melting Glaciers Deform Land
When glaciers melt, the land below deforms. Sea level data show that widely used models oversimplify the process.
Sea Level Science and Applications Support Coastal Resilience
Known for precise, planetary-scale measurements, NASA is improving its decades-long effort to observe and understand sea levels to help communities prepare for the effects of Earth’s rising ocean.
Fresh Approaches to Processing GRACE Data
Two studies showcase new methods for analyzing GRACE data that better match the land surface, producing clearer estimates of mass variations.
Continuity is the Father of Success
Geodetic measurements indicate that Three Sisters Volcano uplifted by almost 300 millimeters in the past 25 years without significant anomalies at the surface.
Lasers and Ultracold Atoms for a Changing Earth
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.
Improving Coseismic Slip Measurements
A physics-based method estimates the duration of earthquakes’ coseismic phase and can help improve the precision of coseismic slip models and magnitude estimates.
New Inversion Method Improves Earthquake Source Imaging
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.
