Seismic Moment Accumulation Rate From Geodesy: Constraining Kostrov Thickness in Southern California
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
20 may 2024
Katherine A. Guns, David T. Sandwell, Xiaohua Xu, ...
Seismic moment accumulation rate is a fundamental parameter for assessing seismic hazard. It can be estimated geodetically from either fault‐...
Global Predicted Bathymetry Using Neural Networks
EARTH AND SPACE SCIENCE
