Seismic, structural, dynamic and static monitoring systems and measurements


What seismic monitoring is

Seismic monitoring in high-risk areas, such as Romania, is very important for the prevention of human lives loss, but also of material loss.

The recorded data in the case of a building monitoring helps to evaluate its safety after a major earthquake, so that it can be decided very easily whether it is necessary to evacuate staff or not.

Also, seismic and vibration monitoring is of major importance in the case of industrial platforms or very old buildings of historical importance. In both cases, based on the information provided by the monitoring systems, measures can be taken in advance to prevent possible disasters.

Roel Systems has as partner for this interesting domain, the Swiss company GeoSIG.
