Tippe Top Inversion as a Dissipation-Induced Instability [PDF]

, 2004
By treating tippe top inversion as a dissipation-induced instability, we explain tippe top inversion through a system we call the modified Maxwell--Bloch equations. We revisit previous work done on this problem and follow Or's mathematical model [SIAM J.

La fabricación de un mito: el terremoto de 1687 y la ruina de los cultivos de trigo en el Perú

, 2000
Uno de los temas mas polemicos en la historiografia sobre el Peru colonial gira en torno a la determinacion de si el gran movimiento sismico que destrozo Lima el 20 de octubre de 1687 fue tambien el causante de la ruina de la produccion de trigo en los ...

Rheological Controls on Creeping Landslides Within the Franciscan Mélange: Insights From Laboratory Experiments

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Landslides and tectonic faults exhibit a spectrum of slip behavior, from steady frictional creep to catastrophic failure. However, the mechanisms controlling slow slip, and slip speed more generally, remains unresolved. Here we report on laboratory shearing experiments on natural samples from the localized shear plane of a well‐instrumented ...

Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide [PDF]

, 2019
The re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir.

The Effect of Pressurization Rate and Pattern on Injection‐Induced Seismicity in Highly Permeable Sandstone: An Experimental Study

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Effectively mitigating induced seismicity in subsurface engineering operations within highly permeable, porous geo‐energy reservoirs requires a clear understanding of how fluid injection parameters influence the seismic response. In this study, we performed injection‐driven fault reactivation experiments on highly permeable saw‐cut Red Felser ...

Effects of Stress and Friction Heterogeneity on Spatiotemporal Complexity of Seismic and Aseismic Slip on Strike‐Slip Faults

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Numerical and laboratory models of earthquake cycles on faults governed by rate‐and‐state friction often show cycle‐invariant behavior, while natural faults exhibit considerable variability in slip history. Possible explanations include heterogeneities in fault stress and frictional properties. We investigate how various types of heterogeneity

Controls of Dynamic and Static Stress Changes and Aseismic Slip on Delayed Earthquake Triggering: Application to the 2019 Ridgecrest Earthquake Sequence

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Dynamic earthquake triggering often involves a time delay relative to the peak stress perturbation. In this study, we investigate the physical mechanisms responsible for delayed triggering. We compute detailed spatiotemporal changes in dynamic and static Coulomb stresses at the 2019 Mw ${M}_{w}$ 7.1 Ridgecrest mainshock hypocenter, induced by ...

Synthesis of the Laboratory Frictional Properties of a Major Shallow Subduction Zone: The Nankai Trough, Offshore SW Japan

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Nankai Trough has a long history of ≥Mw 8 earthquakes and associated tsunamis. It has been the focus of decades of research, including drilling, providing the opportunity to measure the laboratory frictional properties of shallow accretionary prism samples. We collate all available friction data from the Nankai Trough and correlate it with

Earthquake Rupture Dynamics From Graph Neural Networks

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Earthquakes arise from tectonic loading of complex fault systems consisting of heterogeneous material parameters, geometry, rheology, and prestress. All of those are subject to uncertainties, and their interactions and sensitivities for the dynamic rupture problem are incompletely understood.
