Energy radiation from intermediate‐ to large‐magnitude earthquakes: Implications for dynamic fault weakening [PDF]

Journal of Geophysical Research: Solid Earth, 2010
The amount of energy radiated from an earthquake can be measured using recent methods based on earthquake coda signals and spectral ratios. Such methods are not altered by either site or directivity effects, with the advantage of a greatly improved accuracy.

Faults Self-Organized by Repeated Earthquakes in a Quasi-Static Antiplane Crack Model [PDF]

, 1995
We study a 2D quasi-static discrete {\it crack} anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transfered to all elements through elastic forces. This model can

A Review of the Source Parameters of the 1999 Ms7.6 Chi-Chi, Taiwan, Earthquake

Terrestrial, Atmospheric and Oceanic Sciences, 2006
An Ms7.6 Chi-Chi earthquake, which ruptured the Chelungpu fault, struck central Taiwan on 20 September 1999 at 17:47 p.m. GMT. Observed data and inversion results lead to the estimated values of source parameters of the earthquake based on distinct ...

Is the Shroud of Turin in Relation to the Old Jerusalem Historical Earthquake?

, 2015
Phillips and Hedges suggested, in the scientific magazine Nature (1989), that neutron radiation could be liable of a wrong radiocarbon dating, while proton radiation could be responsible of the Shroud body image formation. On the other hand, no plausible

Real-Time Estimation of Fault Rupture Extent Using Envelopes of Acceleration [PDF]

, 2008
We present a new strategy to estimate the geometry of a rupture on a finite fault in real time for earthquake early warning. We extend the work of Cua and Heaton who developed the virtual seismologist (VS) method (Cua, 2005), which is a Bayesian approach

Radiated seismic energy and earthquake source duration variations from teleseismic source time functions for shallow subduction zone thrust earthquakes [PDF]

Journal of Geophysical Research: Solid Earth, 2004
Earthquake source time functions deconvolved from teleseismic broadband P wave recordings are used to examine rupture variations for 417 underthrusting earthquakes located on the interplate interface in circum‐Pacific subduction zones. Moment‐scaled duration of significant moment release varies with depth, with longer‐duration events occurring in the ...

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

, 2006
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...
