Azimuthal propagation of seismo-magnetic signals from large earthquakes in Taiwan
earthquake emission frequency wavenumber method earthquake forecast
2015/8/24
This study uses a network that is comprised of 10 total intensity magnetometers to detect azimuthal propagation of seismo-magnetic emission waves during 26 earthquakes that occurred between July 2007 ...
CURRENT SITUATION OF THE EDUCATIONAL PROJECT ON DISASTER PREVENTION IN TAIWAN
disaster prevention education popularization e-learning
2014/5/9
The Taiwan government has invested much effort in developing and promoting disaster relief and prevention by following out many research projects after the 1999 Chichi earthquake. "Experiment and Deve...
Nonextensive analysis of crustal seismicity in Taiwan
Nonextensive analysis crustal seismicity Taiwan
2010/10/20
Using the Taiwan Central Weather Bureau earthquake catalogue, the crustal seismicity of Taiwan was analyzed by means of a nonextensive approach. The time span of the analyzed catalogue is from 1 Janua...
Numerical earthquake response analysis of the Liyutan earth dam in Taiwan
Numerical earthquake response analysis the Liyutan earth dam Taiwan
2010/10/20
The dynamic response of the Liyutan earth dam to the 1999 Chi-Chi earthquake (ML=7.3) in Taiwan was numerically analyzed. First, the staged construction of the dam was simulated. Then, seepage analysi...
Spatio-temporal Slip, and Stress Level on the Faults within the Western Foothills of Taiwan: Implications for Fault Frictional Properties
The Chi-Chi earthquake fault friction fault rheology stress fault slip distribution
2014/4/15
We use preseismic, coseismic, and postseismic GPS data of the 1999 Chi-Chi earthquake to infer spatio-temporal variation of fault slip and frictional behavior on the Chelungpu fault. The geodetic data...
Interseismic crustal deformation in the Taiwan plate boundary zone revealed by GPS observations, seismicity, and earthquake focal mechanisms
Taiwan Strain rate Seismicity Earthquake focal mechanism GPS
2014/4/9
We use GPS-derived surface velocities, seismicity, as well as estimates of earthquake focal mechanisms from the time period before the 1999 Chi-Chi earthquake to evaluate spatial variations of surface...
Characteristics of chlorites in seismogenic fault zones: the Taiwan Chelungpu Fault Drilling Project (TCDP) core sample
Characteristics of chlorites seismogenic fault zones Taiwan Chelungpu Fault Drilling Project core sample
2010/9/28
The iron content and the asymmetry of iron and magnesium ions in chlorites are examined for the Chelungpu Fault in Taiwan, which is a seismogenic fault. The samples are collected from the cores drille...
Slip rates on the Chelungpu and Chushiang thrust faults inferred from a deformed strath terrace along the Dungpuna river, west central Taiwan
Slip rates on the Chelungpu Chushiang thrust faults a deformed strath terrace along the Dungpuna river west central Taiwan
2014/4/15
The Chelungpu fault produced the September 1999Mw= 7.6 Chi-Chi earthquake,central Taiwan. The shortening rate accommodated by this structure, integrated over several seismic cycles, and its contributi...
Millennialsliprate of the Longitudinal Valley fault from river terraces: Implications for convergence across the active suture of eastern Taiwan
Millennials Pirate Longitudinal Valley fault river terraces Implications for convergence across the active suture eastern Taiwan
2014/4/15
The Longitudinal Valley fault is a key element in the active tectonics of Taiwan. It is the principal structure accommodating convergence across one of the two active sutures of the Taiwan orogeny. To...
Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan
earthquake Chi-Chi Taiwan coseismic imagery Okada
2014/4/15
The 1999 Chi-Chi earthquake,Mw= 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating ...
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 ...
