A repeatable seismic source for tomography at volcanoes
Mt. Merapi tomography active seismics
2015/10/8
One major problem associated with the interpretation of seismic signals on active volcanoes is the lack of knowledge about the internal structure of the volcano. Assuming a 1D or a homogeneous instead...
Seismic transmission tomography: determination of the elastic properties of building structures (some examples)
applied geophysics cultural heritage inversion seismic tomography
2015/9/29
This paper is a general review on seismic transmission tomography considering data acquisition and processing. Some questions on linear and non linear inversions are tackled, and advice given on the c...
The 1998-1999 Pollino (Southern Apennines, Italy) seismic crisis: tomography of a sequence
seismic sequences stress field evolution Southern Apennines Calabrian Arc Pollino Chain
2015/9/10
In 1998-1999 a seismic sequence occurred in the Southern Apennines, after the moderate size (mb=5.0) 9th September
1998 Pollino earthquake. It lasted about 14 months and was clearly localized to the ...
Global seismic tomography and modern parallel computers
Numerical inverse theory seismology global tomography seismic resolution Earth’ s mantle
2015/9/8
A fast technological progress is providing seismic tomographers with computers of rapidly increasing speed and RAM, that are not always properly taken advantage of. Large computers with both shared-me...
Local earthquake tomography of the Erzincan Basin and the surrounding area in Turkey
local earthquake tomography Erzincan Basin 3D velocity structure
2015/9/2
In this study, selected travel time data from the aftershock series of the Erzincan earthquake (March, 1992, Ms=6.8) were inverted simultaneously for both hypocenter locations and 3D Vp and Vs structu...
Electrical resistivity tomography investigations in the ufita Valley (southern Italy).
shallow ERT deep ERT Ufita River valley southern Apennines
2015/9/1
Several Electrical Resistivity Tomography (ERT) surveys have been carried out to study the subsurface structural and sedimentary settings of the upper Ufita River valley, and to evaluate their efficie...
Tomography of the 2011 Iwaki earthquake (M 7.0) and Fukushima nuclear power plant area
Iwaki earthquake Fukushima nuclear power plant area
2015/1/4
High-resolution tomographic images of the crust and upper mantle in and around the area of the 2011 Iwaki earthquake (M 7.0) and the Fukushima nuclear power plant are determined by inverting a large n...
Structure of central and southern Mexico from velocity and attenuation tomography
Structure of central and southern Mexico velocity attenuation tomography
2014/4/10
The 3DVp, Vp/Vs, P- and S-wave attenuation structure of the Cocos subduction zone in Mexico is imaged using earthquakes recorded by two temporary seismic arrays and local stations. Direct P wave arriv...
Recently constructed tomographic models of the lateral heterogeneity of elastic properties in the Earth's mantle are contrasted in terms of their implications concerning the extent to which the endoth...
Swave velocity structure below central Mexico using high‐resolution surface wave tomography
S Wave velocity structure central Mexico high‐resolutionp surface wave tomography
2014/4/10
Shear wave velocity of the crust below central Mexico is estimated using surface wave dispersion measurements from regional earthquakes recorded on a dense, 500 km long linear seismic network. Vertica...
