Significance test for seismicity rate changes before the 1987 Chiba-toho-oki earthquake (M 6.7) Japan
quiescence seismicity rate increasa quantitative analysis significance test the 1987 Chiba-toho-oki earthquake
2015/9/30
A precursory seismic quiescence lasting 1.5 ± 0.5 years was observed prior to the 1987 M 6.7 Chiba-toho-oki earthquake, Central Japan. This event was the largest mainshock to occur in the region in 60...
Paleoseismology and slip rate of the Conway Segment of the Hope Faultat Greenburn Stream,South Island,New Zealand
Hope Fault paleoseismicity ConwaySegment Kaikoura neotectonics slip rate recurrence NZMS 260 sheet 031
2015/9/16
The Conway Segment of the dextral-slip Hope Fault is one of the fastest slipping fault segments along New Zealand s plate boundary, but has not ruptured co-seismically in the historic period and littl...
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...
Modeling the dynamic rupture propagation on heterogeneous faults with rate- and state-dependent friction
dynamic rupture fault constitutive law fault friction stress heterogeneities
2015/9/10
We investigate the effects of non-uniform distribution of constitutive parameters on the dynamic propagation of
an earthquake rupture. We use a 2D finite difference numerical method and we assume tha...
A rate-state model for aftershocks triggered by dislocation on a rectangular fault: a review and new insights

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

2015/9/1
We analyse a microgravity data set acquired from two spring LaCoste & Romberg gravity meters operated in parallel at the same site on Etna volcano (Italy) for about two months (August September 2005)....
Non-permanent GPS data for regional-scale kinematics: reliable deformation rate before the 6 April, 2009, earthquake in the L'Aquila area
GPS Non-permanent station Subsampling Velocity Strain field
2015/8/28
A GPS-based geodetic study at a regional scale requires the availability of a dense network that is characterized by 10 km to 30 km spacing, typically followed in a few continuous GPS stations (CGPSs)...

We document geodetic strain across the Nepal Himalaya using GPS times series from 30 stations in Nepal and southern Tibet, in addition to previously published campaign GPS points and leveling data and...
Scaling of small repeating earthquakes explained by interaction of seismic and aseismic slip in a rate and state fault model
Scaling small repeating earthquakes explained by interaction seismic aseismic slip in a rate state fault model
2014/4/8
Because of short recurrence times and known locations, small repeating earthquakes present a rare predictable opportunity for detailed field observations. They are used to study fault creeping velocit...

Spectral element modeling spontaneous earthquake rupture rate and state faults:velocity-strengthening friction at shallow depths
2014/4/8
We develop a spectral element method (SEM) for simulating dynamic rupture on rate and state faults and use it to study how the rupture is affected by a shallow fault region of steady state velocity-st...
