Prevention of Explosions and Fires caused by Earthquakes

Seismic warning and prediction systems based on precursor data packets were analysed aiming to develop a system to prevent explosions and fires caused by uncontrolled gas leaks following the deterioration of gas networks produced as a result of major seismic movements. At the current stage of knowledge, the accurate prediction in time and intensity of earthquakes is not possible. The simple information about a major earthquake, it is not a sufficient argument for shutting down gases over a large area. Closure of gases in buildings should only be done in the case of some tectonic movements that, on a local level (in that locality) exceed a certain pre-imposed threshold (considered dangerous). In this context, it is considered that an adequate seismic protection system for gas networks in a given locality must ensure: measuring /validating the intensity of local tectonic movements — preferably in 3D; generating a control signal for the closure of gases at the connections of buildings connected to the system — only if the intensity of seismic movements in the locality exceeds an imposed level (considered dangerous); secure digital communication with autonomous UPS power supply between the place of measurement /evaluation of the intensity of local seismic movements and the execution aquatics (electrovalves mounted before the gas regulation /measurement block of the protected buildings).
