The Newport-lnglewood fault zone (NIF) strikes northwest along the western margin of the Los Angeles basin in southern California. The seismicity (1973 to 1985) of M, _-> 2.5 that occurred within a 20-kin-wide rectangle centered on the NIF extending from the Santa Monica fault in the north to Newport Beach in the south is analyzed. A simultaneous full inversion scheme (VELEST) is used to invert...

On May 23, 1989, a great earthquake struck a remote region of the South Pacific Ocean between New Zealand and Antarctica. The nearby islands are Macquarie Island, about 300 km south of the epicenter, and Campbell Island, almost 600 km east of the epicenter; the latter experienced shaking with intensity V. Fortunately, both islands are sparsely inhabited and litfie damage or injuries were report...

We present a catalog of accurate epicenter coordinates of earthquakes located in the Gulf of California (GoC) in the period 2002-2014 that permits us to analyze the seismotectonics and to estimate the depth of the seismogenic zone of this region. For the period April 2002 to December 2014 we use body-wave arrival times from regional stations of the Broadband Seismological Network of the GoC (RE...

This paper presents a cartographic framework based on algorithms of GMT codes for mapping seismically active areas in Venezuela. The data included raster grids from GEBCO, EGM-2008, and vector geological layers the USGS. were iteratively processed console GMT, converted by GDAL, formatted, mapped geophysical visualisation; QGIS was applied mapping. We analyzed 2000 samples earthquake events obt...

In recent decades, geological modeling has significantly evolved, relying on the growing potential of hardware and software to manage integrate vast datasets 2D-3D geophysical underground data. Therefore, digitization integration with other forms data can often improve understanding systems, even when using so-called vintage or historical Seismic reflection have been extensively acquired mainly...
