Geologic imaging technique measures strength of Earth’s outer shell
Geologic imaging technique measures strength Earth’s outer shell
2016/9/29
An advanced imaging technique used to map Earth’s outer shell also can provide a measure of strength, finding weak spots and magma upwellings that could point to volcanic or earthquake activity, accor...
Wavelength influence in sub-pixel temperature retrieval using the dual-band technique
remote sensing volcanoes dual-band DAIS sensor hyperspectral analysis
2015/9/7
The thermal model proposed by Crisp and Baloga (1990) for active lava flows considers thermal flux as a function of the fractional area of two thermally distinct radiant surfaces. In this model, the l...
A technical note on the bias in the estimation of the b-value and its uncertainty through the Least Squares technique
b-value Seismology Least Squares technique Synthetic-earthquake catalogs
2015/9/2
We investigate conceptually,
analytically, and numerically the biases in the estimation of the
b-value of the Gutenberg-Richter law and of
its uncertainty made through the least

Integrated inversion of ground deformation and magnetic data at Etna volcano using a genetic algorithm technique
ground deformation magnetic anomalies inverse modelling genetic algorithms Mt. Etna
2015/9/2
Geodetic and magnetic investigations have been playing an increasingly important role in studies on Mt. Etna eruptive processes. During ascent, magma interacts with surrounding rocks and fluids, and i...
Parallelisation technique for serial 3D seismic codes:SMS approach
parallel computing SMS seismic wave propagation numerical simulations site effects
2015/8/28
We investigate a fast and easy way to parallelise seismological serial codes mainly oriented for simulating the seismic wave propagation through anelastic dissipative media. Having an efficient modell...
A case study of detecting the triplet of 3S1 using superconducting gravimeter records with an alternative data preprocessing technique
Seismic normal mode Superconducting gravimeters data Hilbert-Huang transformation Multi-station experiment 3S1 triplet
2015/8/24
Due to their very low noise levels in the low frequency band (<1 mHz), superconducting gravimeters (SGs) are particularly suitable to observe long-period free oscillations of the Earth. This case stud...

A technique for calculating meteor plasma density and meteoroid mass from radar head echo scattering
Meteors Meteoroids Rada Radio observations
2003/3/22
Large-aperture radars detect the high-density plasma that forms in the vicinity of a meteoroid and moves approximately at its velocity;
reflections from these plasmas are called head echoes. To deter...
