Application and Validation of a Multi-block Constitutive Model at Landslides of the Wenchuan Earthquake
Wenchuan earthquake multi-block model seismic displacement landslides back analysis strain softening
2018/6/13
A multi-block model and a corresponding computer program have been developed which predict the kinematics of landslides. Furthermore, a unique event for studying different models simulating the trigge...
A single-station model suitable for f0F2 mapping
radio wave propagation ionosphere ionospheric mapping single station models
2015/10/8
Ionospheric monthly-median values of the F2 and E layer critical frequencies from 24 mid-latitude European stations are fitted to a second degree polynomial and their correlation is discussed. The res...
A comparison of f0F hmE model calculations with El Arenosillo digisonde observations. Seasonal variations
Ionospheric E-layer-theoretical modeling solar EUV nitric oxide
2015/10/8
Seasonal variations of hmE and f0F2 are analyzed using El Arenosillo digisonde observations during solar minimum (1995-1996). Unlike some widely used empirical models daytime hmE show seasonal variati...
On the validity of the regional time and magnitude predictable model in China
time dependent seismicity validation test China
2015/9/30
A simplified form of the "regional time and magnitude predictable model" gives the time interval, T, between two successive mainshocks in a region and the magnitude, Mf, of the following mainshock by ...
Relaxation creep model of impending earthquake
Earthquake fractal zone creep of rocks relation of load short-term precursor
2015/9/28
The alternative view of the current status and perspective of seismic prediction studies is discussed. In the problem of ascertainment of the uncertainty relation Cognoscibility-Unpredictability of Ea...
A three-stage faulting model explains the observed quantitative relations between long-term precursory seismicity, mainshocks and aftershocks. Seismogenesis starts with the formation of a major crack,...
A possible model for initiationof ULF oscillation in magma
ULF oscillations magma volcano electromagnetic emission
2015/9/14
During the period just prior to an earthquake, an electomagnetic emission develops over seismic zones. In this paper, a model of excitation of magnetic fields over zones of volcanic activity is propos...
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 ...
