"In theory, theory and practice are the same. In practice, they are not." Albert Einstein.

"Under the most rigorously controlled conditions of pressure, temperature, volume, humidity, and other variables, the Earth will do as it damns well pleases." Harvard Law.

Objectives and Strategy Back to Top

Subject: From deformation field measurement to the edifice structures and eruptive process dynamics

Monitoring of active volcanoes have to be based on real time observations and a dynamic quantitative model which helps to interpret them. This model is constructed from fundamental studies of mechanical behaviour, structures, magma dynamics and regional tectonic context, allowing also to go deeper into our knowledge of the volcanic system and its evolution.

Basic principles of magma and gas phenomenology start to be well understood [Jaupart, 1994; Neri and Macedonio, 1996]. On the other hand, direction of explosions, lava domes collapses, and the involved volumes during eruptions, still remain difficult to predict, while they are mandatory for volcanic risk evaluation. Indeed, numerical models need initial and boundary conditions, common to the magma dynamics and the mechanics of the volcano. This concerns as well physical and chemical characteristics of the source than the structure of the volcano: geometry of the magma chamber and conduit, fractures, topography and mechanical properties of the medium. These conditions are specific to each volcano and change with time. They presently have been estimated for a dozen of the 600 world active volcanoes. To participate in this domain, I propose two complementary axes of rechearch:

These two studies are based on precise observations. Regarding the desired precision and the complexity of involved phenomena, the multiparameter approach seems to be the once allowing a true validation of measured signals. I propose two additional methodological approaches:

This should lead to the possibility of determining more quantitative models of eruptive processings, then (I hope) will help the volcanic hazard mitigation.

Physicist (Physicien) is a french State function belonging to the Astronoms & Physicists Corpus. This is equivalent to University Professor status. We are in charge of six missions regarding the Earth Sciences and Observations (see the official definition in French):

  1. Fundamental, applied or technological research and its valorization ;
  2. Data collection in natural environments ;
  3. Monitoring and forecasting of natural phenomena ;
  4. Management of research ressources ;
  5. International cooperation ;
  6. Training, teaching and spreading of the scientific and technical knowledge.
