Studying the volcanoes

 

The study of the procesess that occur in volcanic areas can be approached through empirical and phenomenological methods relying on statistical basis, or through a theoretical and numerical modeling based on a physical ground.

The statistical modeling allows to identify the relevant parameters in a system endowed with a high number of degrees of freedom, and to estimate these parameters directly from data. The simultaneous study of several different volcanoes makes available many more quantitative data, and helps to detect analogies in the pre-eruptive processes.

The volcanic complexes, as the most of the geophysical systems, are inaccesible and guest physical processes occurring over time periods too long to be followed directly. The theoretical modeling is a "trnslation" of the physics in mathematical terms; it can reproduce the behviour of the system, which can be controlled by the scientist, in order to understand the role of the governing parameters, and tell which ones play a key-role, and then deserve a special attention in the monitoring and measurement activity.
