Was the magnitude (M = 9.0R) of the mega-earthquake of Japan (11th of March, 2011) predictable? An analysis based on the Lithospheric Seismic Energy Flow Model (LSEFM)
Tohoku earthquake earthquake magnitude lithosphere cumulative seismic energy mega-earthquakes seismic potential maps
2012/4/20
The Tohoku EQ (11th of March, 2011, M = 9.0) in Japan falsified the proposed EQ magnitude range (M = 7.0 - 8.5) of the same seismogenic regional area that had been determined by the compiled hazard ma...

Magnitude 9.0 Tohoku-Oki Earthquake Mosaicing the Megathrust Seconds to Centuries
2014/4/9
Geophysical observations from the 2011 moment magnitude (Mw) 9.0 Tohoku-Oki, Japan earthquake allow exploration of a rare large event along a subduction megathrust. Models for this event indicate that...
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...

2017/4/12
Radon in soil gas had been measured at 39 locations, distributed along three prominent lineaments in the Guwahati
city, Assam, India; using solid state nuclear track detectors. The most suitable site...
Continuous radon monitoring in the Jowshan hot spring as an earthquake precursor, SE Iran
earthquake precursor Jowshan hot spring continuous monitoring
2017/4/12
In this paper, we present the results of the first experience for spring water 222Rn concentration continuous monitoring
in Jowshan hot spring, SE Iran, from December 2007 to July 2008. This hot spri...
Long range gas-geochemical anomalies of a remote earthquake recorded simultaneously at distant monitoring stations in India
thermal spring gas-geochemical monitoring

Superficial simplicity El Mayor–Cucapah earthquake Baja California in Mexico
2014/4/9
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures 1–6. The fault system that runs ...
Spectral‐element simulations of long‐term fault slip: Effect of low‐rigidity layers on earthquake‐cycle dynamics
Spectral‐element simulations of long‐term fault slip low‐rigidity layers earthquake‐cycle dynamics
2014/4/8
We develop a spectral element method for the simulation of long‐term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.
Our approach reproduces all stages of ...
Three‐dimensional FEM derived elastic Green’s functions for the coseismic deformation of the 2005Mw8.7 Nias‐Simeulue, Sumatra earthquake

Using finite element models (FEMs), we examine the sensitivity of surface displacements to the location of fault slip, topography, and three‐dimensional variations in elastic moduli in the context of ...
Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake
postseismic deformation the lower crust following the 2004 Mw6.0 Parkfield earthquake
2014/4/15
Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from...
We present a source model for the 2001Mw7.6 Bhuj earthquake of northwest India. The slip distribution suggests a high stress drop (～35 MPa) and, together with the depth distribution of aftershocks, th...
