NATURAL HAZARDS AND RISK MITIGATION   Electromagnetic phenomena related to earthquakes and volcanoes

The attenuation of the consequences of the natural disasters is one of the challenges of  XXI^e century. It requires a good adequacy between the development of monitoring methods likely to detect any abnormal behaviour of the natural environment and the comprehension of the mechanisms at the origin of these catastrophes. These two complementary approaches require specific and long search in natural environments which one controls practically none the experimental parameters (occurrence of the event, localization, amplitude …).

Our group is mainly concerned by magnetic, electric and electromagnetic methods applied to:

• The imagery of volcanic structures and active faults, as well as ground fluid flow,

• The monitoring of volcanic activity and processes leading to earthquakes.
