Recently, innovative algorithms for 2D and 3D tomographic data inversion, new models for describing the electrokinetic phenomena associated to the subsurface fluid migration, and modern ICT technologies (i.e., sensor web) for the field data acquisition have rapidly transformed the electrical methods in a powerful tool for geohazard and environmental monitoring. These technological and methodological improvements disclose the way for a wide spectrum of novel and challenging applications: mapping of the water content in landslide bodies, identification of fluid and gas emissions in volcanic areas, studying the salt water intrusion in coastal areas, and so fourth. To date, the electrical imaging can be considered as one of the most interesting geophysical methods for the geohazard and environmental monitoring.

Researchers are invited to submit papers to this special issue focussing the attention to the following methodological aspects:

• Self-potential tomography
• Electrical resistivity tomography
• Induced polarization
• Time-lapse tomography
• Joint inversion of self-potential and resistivity data
• Integration and comparison with other in situ, airborne, and satellite EM technologies

Furthermore, we strongly encourage the submission of papers concerning novel applications of the electrical methods. Potential topics include, but are not limited to:

• Imaging of tectonic and volcanic structures
• Mapping and monitoring of fluids in geothermal areas
• Electrical methods for the seismic microzonation
• Electrical monitoring of landslides
• Hydrogeophysics: comparison between electrical methods and simulation codes (FeFLOW) to vadose zone (wetting front)
• Mapping soil and water pollutants: monitoring of waste disposal and industrial sites
• Monitoring of coastal environment, pore aquifers, and saltwater intrusion
• Electrical methods and petrophysical parameters
• Biogeophysics: geophysical signatures of microbial interactions with the subsurface
• EM measurements for studying soil-vegetation interactions
