Research progress on layered seismic anisotropy - A review

open access: yesEarthquake Research Advances, 2021
Seismic anisotropy is an effective feature to study the inner structure of the Earth. In complex tectonic area, the assumption of single-layer anisotropy is sometimes not well consistent with the observed data; thus, the assumption of multi-layered (i.e.

Anomalous stress diffusion in earthquake triggering: Correlation length, time dependence, and directionality [PDF]

open access: yes, 2003
It has been recently suggested that moderate and large earthquakes can be triggered by similarly sized events at very long range. Here we study the main characteristics of earthquake triggering by determining its correlation length, time dependence, and ...

Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges

open access: yes, 2020
Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,

Earthquake Source Characterization Using 3D Numerical Modeling [PDF]

open access: yes, 2007
To understand the physics of earthquakes, it is important to know what happens during individual events. Dissembling the information about the source process from the recorded seismograms is a difficult and non-unique process, as there are severe trade ...

Hydrochemistry of the Hot Springs in Western Sichuan Province Related to the Wenchuan MS 8.0 Earthquake

open access: yesThe Scientific World Journal, 2014
Hydrogeochemistry of 32 hot springs in the western Sichuan Province after the Wenchuan MS 8.0 earthquake was investigated by analyzing the concentrations of cation and anion and the isotopic compositions of hydrogen and oxygen.

Coupling fraction model to interpret the motion of non-fully coupled strike-slip faults

open access: yesFrontiers in Earth Science, 2023
Despite coupling fractions being extensively used in the interseismic period, the coexistence of locking and creeping mechanisms and the correlation between the coupling fraction and locking depth remain poorly understood because of the lack of a ...

Recognition of earthquake-prone areas in the Altai-Sayan-Baikal region based on the morphostructural zoning

open access: yesRussian Journal of Earth Sciences, 2021
The goal of the study is to identify the possible locations of strong M6+ earthquakes in the Altai-Sayan-Baikal region. The first stage of the study is compiling the morphostructural map of the region by means of the morphostructural zoning method (MSZ).

The global earthquake history

open access: yes, 2014
The study of earthquakes from historical sources, or historical seismology, was considered an early priority for the Global Earthquake Model (GEM) project, which commissioned a study of historical seismicity on a global scale.

Information theoric framework for the earthquake recurrence models: Methodica Firma per Terra Non-Firma

open access: yes, 2006
This paper first evaluates the earthquake prediction method (1999) used by US Geological Survey as the lead example and reviews also the recent models. Secondly, points out the ongoing debate on the predictability of earthquake recurrences and lists the ...
