earth-movement monitoring

Accident caused by movement of earth's crust

isostatic land movements

Is there any chance, through pressure and normal movement of the earth's crust, that there would be any sinkholes that form as a consequence of the gas coming out?

In a second stage, however, it should gradually replace national surveillance systems at land and maritime borders, providing a cost-efficient solution, including e. g. a combination of radar and satellite surveillance at European level, taking into account on-going developments realised in the framework of GMES (Global Monitoring for Environment and Security. EUROSUR will benefit from experience at national and European level with similar surveillance systems; possible synergies with existing European surveillance systems for other purposes should also be explored. In the maritime domain, the vessel monitoring system SafeSeaNet is curr ...[+++]ently under development together with the Member States. The system aims at providing information on ships' movements and their cargoes. EUROSUR might add to the effectiveness of SafeSeaNet, if the systems recognise each other and cooperate. Finally, the possibility for participation of neighbouring third countries in EUROSUR should be considered.

Those are indications that there is something happening in the crust under our feet, that there is definitely stress being built up and released in the form of fault movements.
