Resistivity and heterogeneity of Earth crust in an active tectonic region,Southern Tuscany (Italy)
crustal exploration magnetotellurics geothermal areas
2015/9/14
Southern Tuscany, belonging to the inner zone of the Northern Apennines, Italy, is an ideal laboratory for observing the physical features of the lithosphere and their evolution in tectonically active...
Ez-response as a monitor of a Baikal rift fault electrical resistivity:3D modelling studies
Baikal rift zone electromagnetic monitoring transfer functions resistivity changes ofthe fault
2015/9/14
3D numerical studies have shown that the vertical voltage above the Baikal deep-water fault is detectable and that respective transfer functions, Ez-responses, are sensitive to the electrical resistiv...
Late Quaternary activity along the Scorciabuoi Fault (Southern Italy) as inferred from electrical resistivity tomographies
active tectonics Apennines geoelectrical survey Holocene Val d’ Agri
2015/9/2
The Scorciabuoi Fault is one of the major tectonic structures affecting the Southern Apennines, Italy. Across its central sector, we performed several electrical resistivity tomographies with differen...
Development of geothermal field following the 2000 eruption of Usu volcano as revealed by ground temperature,resistivity and self-potential variations
Usu volcano geothermal field ground temperature electrical prospecting selfpotential field hydrothermal circulation
2015/9/2
The 2000 eruption of Usu volcano, NE Japan, took place on the foot of the somma, and formed a cryptodome of 65 m high accompanying numerous faults. We made repeated measurements of ground temperature,...
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...

Colfiorito fault system magnetotellurics geoelectrics fluids
2015/9/1
Over the last decade electromagnetic (EM) measurements have provided new constraints on the upper-crustal structure of the major fault zones in the world, both when they act as conduit and as a barrie...
Electrical resistivity tomography investigation of coseismic liquefaction and fracturing at San Carlo,Ferrara Province,Italy
Liquefaction Fracturing Electrical resistivity tomography
2015/8/26
Massive surface fracturing and sand ejection took place during the main shock of the May 20, 2012, earthquake (Ml = 5.9) in the Emilia-Romagna region, northern Italy. These phenomena were induced by t...
Contribution of 3-D electrical resistivity tomography for landmines detection
3-D electrical resistivity tomography landmines detection
2009/11/2
Landmines are a type of inexpensive weapons widely used in the pre-conflicted areas in many countries worldwide. The two main types are the metallic and non-metallic (mostly plastic) landmines. They a...
Joule heating and anomalous resistivity in the solar corona
Joule heating anomalous resistivity solar corona
2009/10/30
Recent radioastronomical observations of Faraday rotation in the solar corona can be interpreted as evidence for coronal currents, with values as large as 2.5×109 Amperes (Spangler, 2007). These estim...
Resistivity Distribution in the Gediz Graben and its Implications for Crustal Structure
Gediz graben magnetotelluric resistivity conductive lower crust
