A Deep Learning‐Based Surrogate Model for Seismic Data Assimilation in Fault Activation Modeling
International Journal for Numerical Methods in Engineering, Volume 126, Issue 8, 30 April 2025.ABSTRACT Assessing the safety and environmental impacts of subsurface resource exploitation and management is critical and requires robust geomechanical modeling. However, uncertainties stemming from model assumptions, intrinsic variability of governing parameters, and data errors challenge the reliability of predictions.

First Optical Seismometer at the Top of La Soufrière Volcano, Guadeloupe
, 2020 Accurate monitoring of volcanic activity demands expertise in fields including geophysics, geology, and geochemistry. Data obtained from the most recent technical advances are particularly vital in pre-eruptive phases. In particular, seismic monitoring

Constraining the stochastic gravitational wave background using the future lunar seismometers [PDF]
Phys. Rev. D 110 (2024) 043009Motivated by the old idea of using the moon as a resonant gravitational-wave (GW) detector, as well as the recent updates in modeling the lunar response to GWs, we re-evaluate the feasibility of using a network of lunar seismometers to constrain the stochastic GW background (SGWB). In particular, using the updated model of the lunar response, we derive

Chigaku Zasshi (Jounal of Geography), 2008 Andrija Mohorovicic (1857-1936) is a world-famous Croatian geophysicist and the discoverer of the Earth's crust/mantle boundary known as the Moho-discontinuity. The historical seismometer used by A. Mohorovicic to detect the Moho in 1909 is still maintained in working conditions, and is displayed in the Department of Geophysics of the University of ...

Large Megathrust Earthquakes Tend to Sustain an Increasingly Longer Duration Than Expected
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract The moment‐duration (M0‐T) scaling law reveals fundamental earthquake physics across various sizes and tectonic settings. However, the validity of the cubic relation (M0 ∝ T3) inferred for large (Mw ≥ 7) megathrust events has been recently questioned due to the scarcity of observations and similarities to slow earthquakes.
