When an 8.2-magnitude earthquake struck off the coast of Chignik, Alaska, on July 29, geophysicist Geoffrey Abers did the logical – if not simple – thing.
He raced to Alaska with a group of collabora...
Seismologists monitor Ridgecrest quake aftershocks using novel fiber optic network（图）
Seismologistsr Ridgecrest quake aftershocks novel fiber optic network
2019/10/22
Seismologists at Caltech are using fiber optic cables to monitor and record aftershocks from the 2019 Ridgecrest earthquake in greater detail than previously possible. Thousands of tiny aftershocks ar...
Study Finds Earthquakes Can Trigger Near-Instantaneous Aftershocks on Different Faults
Earthquakes Trigger Near Aftershocks Different Faults
2016/9/29
According to a new study by scientists at Scripps Institution of Oceanography at the University of California San Diego, a large earthquake on one fault can trigger large aftershocks on separate fault...
Estimation of seismic moments from local magnitudes and coda durations for the Cairo earthquake aftershocks recorded at Kottamyia (KEG) Broadband station
aftershocks seismic moment scaling
2015/9/17
The spectral analysis of fifty-five KEG VBB records from the October 12, 1992 Cairo earthquake source region
was performed to obtain the seismic moment. We obtained this parameter in turn to develop ...
The oscillatory behaviour of the aftershocks rate of the 2001 Bhuj earthquake, India: observation and interpretation
aftershocks Bhuj earthquake Omori'sLaw GBA array Lg magnitude
2015/9/14
A damaging earthquake of Mw 7.7, which struck the Bhuj region of India on January 26, 2001, was followed by a large number of aftershocks. The aftershock data available at Gauribidanur Seismic Array S...
A rate-state model for aftershocks triggered by dislocation on a rectangular fault: a review and new insights
aftershocks earthquake triggering fault parameters rate-and-state Omori law
2015/9/8
We compute the static displacement, stress, strain and the Coulomb failure stress produced in
an elastic medium by a finite size rectangular fault after its dislocation with uniform stress drop
but ...
Analysis of the spatial distribution between successive earthquakes in aftershocks series
Aftershocks Earthquake catalogs Spatial distribution Scaling
2015/8/18
The earthquake spatial distribution is being studied, using catalogs for different recent aftershock series. The quality of the available data, taking into account the completeness of the magnitude, i...
Triggering of Aftershocks of the Japan 2011 Earthquake by Earth Tides
Japan 2011 earthquake, Aftershock Triggering, Earth tides
2011/9/1
The aftershock sequence of the devastating Japan earthquake of March 2011 is analyzed for the presence of periodicities at the Earth tide periods. We use spectral analysis as well as a time-domain met...
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviat...
Loading rates in California inferred from aftershocks
Loading rates California aftershocks
2009/10/30
We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static ...
Modeling afterslip and aftershocks following the 1992 Landers earthquake
Modeling after slip aftershocks following Landers earthquake
2014/4/15
One way to probe the rheology of the lithosphere and fault zones is to analyze the temporal evolution of deformation following a large earthquake. In such a case, the lithosphere responds to a known s...
Geodetic displacements and aftershocks following the 2001 Mw= 8.4 Peru earthquake: Implications for the mechanics of the earthquake cycle along subduction zones
Geodetic displacements aftershocks following 2001 Bmw= 8.4 Peru earthquake earthquake cycle along subduction zones
2014/4/15
We analyzed aftershocks and postseismic deformation recorded by the continuous GPS station AREQ following theMw= 8.4, 23 June 2001 Peru earthquake. This station moved by 50 cm trenchward, in a N235E ...
Fault systems of the 1971 San Fernando and 1994 Northridge earthquakes, southern California: Relocated aftershocks and seismic images from LARSE II
crustal structure tectonics earthquakes seismic imaging southern California
2014/4/10
We have constructed a composite image of the fault systems of the M 6.7 San Fernando (1971) and Northridge (1994), California, earthquakes, using industry reflection and oil test well data in the uppe...
Postseismic relaxation driven by brittle creep: A possible mechanism to reconcile geodetic measurements and the decay rate of aftershocks, application to the Chi-Chi earthquake, Taiwan
postseismic relaxation Omori law Chi-Chi earthquake
2014/4/15
We evaluate the effect of coseismic stress changes on the fault slip at midcrustal depth, assuming a velocity-strengthening brittle creep rheology. We show that this model can help reconcile the time ...
