Aim of this work is to show evidences for pre-earthquake processes and to set up earthquake forecasting experiments, based on two hypotheses: 1) extreme change of the activity of underwater methane seeps appears days before earthquakes; 2) effects from increase of shallow water seeps emissions are visible on satellite images.
