Rupture dynamics and fault mechanics of intraplate earthquakes in Brazil

2020
<p>Mitigating intraplate earthquakes is necessary, as local populations are at risk both directly from strong shaking and indirectly from the threat to public infrastructure such as dams. However, the infrequency of these events and insufficient knowledge of how the ground will respond to passing seismic waves challenges ...

Dynamic rupture in a layered medium: The 1966 Parkfield earthquake

Bulletin of the Seismological Society of America, 1980
abstractA method for computing ground motion from a propagating stress relaxation in a vertically heterogeneous medium was developed wherein computational efficiency is enhanced by separating the source, a three-dimensional calculation, from the wave propagation, a two-dimensional calculation.

A Suite of Exercises for Verifying Dynamic Earthquake Rupture Codes

Seismological Research Letters, 2018
We describe a set of benchmark exercises that are designed to test if computer codes that simulate dynamic earthquake rupture are working as intended. These types of computer codes are often used to understand how earthquakes operate, and they produce simulation results that include earthquake size, amounts of fault slip, and the patterns of ground ...

The dynamic rupture process of the 1993 Kushiro‐oki earthquake

Journal of Geophysical Research: Solid Earth, 1996
We have constructed a dynamic rapture model of the 1993 Kushiro‐oki earthquake (Mw= 7.6) that is consistent with the observed seismograms. This earthquake occurred beneath the city of Kushiro, Japan, at a depth of about 100 km, and the aftershocks are limited to a horizontal plane between a double seismic zone in the subducting slab.

Dynamic Rupture Simulation Integrated with Earthquake Observations

2014
Dynamic rupture simulations are unique in their contributions to the study of earthquake physics. The current rapid development of dynamic rupture simulations poses several new questions: Do the simulations reflect the real world? Do the simulations have predictive power? Which one should we believe when the simulations disagree?

Direct observations of a dynamic earthquake rupture in the lower crust

2020
<p>A significant number of studies in recent years have demonstrated that earthquakes in the lower crust are more abundant than previously thought. Specifically in continental collision zones, earthquakes are suggested to play a crucial role in permitting fluid infiltration and driving metamorphic transformation processes in ...

Gouge formation by dynamic pulverization during earthquake rupture

Earth and Planetary Science Letters, 2005
Abstract It is proposed here that fault gouge forms by rock pulverization within the tip region of a fast propagating earthquake due to the intensity of stress and rates of strain in this zone. To examine this mechanism, we calculate the deformation conditions of a dynamic shear fracture propagating close to the limiting Rayleigh wave velocity.

Zooming into earthquake ruptures: from kinematics to dynamic

2022
Earthquakes, especially the large ones, cause huge hazards and threaten people living nearby. It is important to improve our understanding of the earthquake source process. I do so by combining seismic data, observations, and simulation of dynamic ruptures.

Analysis and extension of earthquake rupture dynamics

Geophysics is a broad field that explains phenomenons on earth from an interdisciplinary and data rich perspective. One of its modern ramifications is earthquake rupture dynamics, in which the material properties and the stress field are collapsed onto a compact support in which maximum shear deformation localizes -or the fault plane is defined-, and ...
