Pulse-like and crack-like ruptures in experiments mimicking crustal earthquakes
earthquake physics mechanics of faulting rupture modes shear cracks velocity-dependent friction
2014/4/8
Theoretical studies have shown that the issue of rupture modes has important implications for fault constitutive laws, stress conditions on faults, energy partition and heat generation during earthqua...
Ground-improvement methods might protect against earthquakes
Ground-improvement methods protect against earthquakes
2014/3/28
WEST LAFAYETTE, Ind. — Researchers from the University of Texas at Austin's Cockrell School of Engineering are developing ground-improvement methods to help increase the resilience of homes and low-ri...
A catalogue of non-tectonic earthquakes in central-eastern Italy
Quarry blasts Non-tectonic earthquakes Waveforms similarity
2015/8/17
Quarry explosions and other non-tectonic signals can contaminate seismic catalogues, especially in areas where dense seismic networks allow to detect even low energy events. This paper presents the al...
Disaster Medical Assistance Teams After Earthquakes in Iran:Propose a Localized Model
Earthquake Composition Disaster Medical Assistance Teams Iran
2015/10/8
Background: In the past 10 years, 13 fatal earthquakes have occurred in Iran and led to death of 30,000 people whom most of them were killed in the earlier hours of the disaster. Disaster Medical Assi...
Convergence of the frequency-size distribution of global earthquakes
frequency-size distribution global earthquakes
2014/5/19
The Gutenberg-Richter (GR) frequency-magnitude relation is a fundamental empirical law of seismology,but its form remains uncertain for rare extreme events.Here, we show that the temporal evolution of...
The limits of predictability of volcanic eruptions from accelerating rates of earthquakes
Time-series analysis Volcano seismology Statistical seismology
2014/5/19
Volcanic eruptions are commonly preceded by increased rates of earthquakes. Previous studies argue that in some instances these sequences follow the inverse Omori law (IOL) and that this model could b...
Modeling the 2012 Wharton basin earthquakes off-Sumatra: Complete lithospheric failure
Wharton basin earthquakes in-Sumatra Complete lithospheric failure
2014/4/15
A sequence of large strike-slip earthquakes occurred west of Sunda Trench beneath the Wharton Basin. First reports indicate that the main shock was extremely complex, involving three to four subevents...
Testing Geographical Methodology and Tools for the Study of Territories Damaged by Earthquakes. The Case of L’Aquila and Other Localities Three Years after the April 6th 2009 Event
L’Aquila Earthquake Aerial Photographs City of Men
2013/3/11
In this paper, we discuss a geographical methodology supported by specific geo-technologies which we are testing for the study of territories damaged by the L’Aquila earthquake of 6 April 2009 and whi...
The Influence of Earthquakes on Open-Pit Slope Stability
Earthquakes Open-Pit Slope Stability Safety Factor Pseudostatic Approach
2013/3/11
Estimation of stability of natural slopes, embankments, dams and open-pit slopes during earthquakes are complex and non-linear problems, therefore physical modeling is used for decision of it. As a re...
Groundwater Over-Pumping and Recent Earthquakes in the Northern United Arab Emirates: A Natural Hazard Accentuated by Human Activity
Groundwater Over-Pumping Earthquakes Northern UAE Human Impact
2013/3/19
At the present day the United Arab Emirates (UAE) is on the flank of the Arabian plate, but some way away from the major modern earthquake epicentres. It normally experiences only minor earthquakes wh...
FUSION OF MULTI PRECURSORS EARTHQUAKE PARAMETERS TO ESTIMATE THE DATE, MAGNITUDE AND AFFECTED AREA OF THE FORTHCOMING POWERFUL EARTHQUAKES
Hazards earthquake precursor prediction integration satellite data ionosphere
2014/4/28
Since not any individual precursor can be used as an accurate stand alone means for the earthquake prediction, it is necessary to integrate different kinds of precursors. The precursors selected for a...
Marked Increases in Background Photon Emissions in Sudbury Ontario More than One Week before the Magnitude > 8.0 Earthquakes in Japan and Chile
Photon Emissions Seismic Events Earthquake Antecedents
2013/3/8
Daily, minute-to-minute measurements of ground level photon emissions in Sudbury, Ontario Canada displayed conspicuous increases more than one week before the 2011 M9.0 earthquake in Japan and the 201...
Study on Correlation of Tidal Forces with Global Great Earthquakes
Tidal Force Earthquake Run Test Seismic Belt
2013/3/7
The correlation between the celestial tidal forces and earthquakes has been a controversial problem, although its research history is very long. This paper analyzes the relation between the tidal forc...
Anomalously steep dips of earthquakes in the 2011 Tohoku-Oki source region and possible explanations
subduction zone the 2011 Tohoku-Oki earthquake focal mechanism fault geometry seamount fault zone structure
2014/4/9
The 2011Mw9.1 Tohoku-Oki earthquake had unusually large slip (over 50 m) concentrated in a relatively small region, with local stress drop inferred to be 5–10 times larger than that found for typical ...
Searching for seismo-ionospheric earthquakes precursors: Total Electron Content disturbances before 2005-2006 seismic events
seismo-ionoispheric earthquake precursors total electron content of ionosphere lithosphere-atmosphere-ionosphere coupling
2012/5/17
During earthquakes preparation periods significant disturbances in the ionospheric plasma density are often observed. These anomalies are caused by lithosphere-atmosphere-ionosphere interaction, parti...
