Seismicity of Southern California [PDF]

open access: yes, 1954
Evidence for regional seismicity is of four kinds: (1) geological field observation of fault phenomena, (2) historical documents, (3) instrumental recording, and (4) field investigation immediately after ...

Modeling seismic wave propagation and amplification in 1D/2D/3D linear and nonlinear unbounded media

open access: yes, 2010
To analyze seismic wave propagation in geological structures, it is possible to consider various numerical approaches: the finite difference method, the spectral element method, the boundary element method, the finite element method, the finite volume ...

Derivation of the Gutenberg-Richter Empirical Formula from the Solution of the Generalized Logistic Equation

open access: yes, 2012
We have written a new equation to study the statistics of earthquake distributions. We call this equation "the generalized logistic equation". The Gutenberg-Richter frequency-magnitude formula was derived from the solution of the generalized logistic ...

Pore Wetting Phenomena: Implications to Enhanced Oil Recovery and Geologic Carbon Storage

open access: yesEnergy Procedia, 2014
AbstractPore wetting has been considered as an important factor in carbon storage and enhanced oil recovery. Previous studies were limited to the wetting measurements on flat substrates; few measurements were directly carried in a pore to indicate the pore wetting.

Satellite SAR Interferometry for Earth’s Crust Deformation Monitoring and Geological Phenomena Analysis

open access: yes, 2016
SAR Interferometry (InSAR) and the related processing techniques provide a unique tool for the quantitative measurement of the Earth's surface deformation associated with certain geophysical processes (such as volcanic eruptions, landslides and earthquakes), thus making possible long-term monitoring of surface-deformation and analysis of relevant ...

GEOLOGICAL PHENOMENA IN THE AREA OF THE VILLAGES OF GARA BOV AND BOV (WESTERN BULGARIA)

open access: yes
ABSTRACT. The villages of Gara Bov and Bov are located on the border between the Srednogorska and Zapadnobalkanska zones, in the Golema Planina Mountain, part of the Western Stara Planina Mountain. Several geological phenomena were formed in the Triassic rocks (Petrohan Terrigenous Group) and in the Jurassic rocks (the Kostina Fm, the Ozirovo Fm, the ...
