Read the Case Study of a new monitoring system in Iran (pdf). The system consists of R-sensors' seismometers and geophones and Geoarmatech's seismic recorders.
The research goal was to develop a new seismic monitoring system for historical buildings in Isfahan, Iran, and compare the results of the FTA (free-to-air) measurements to the measurements at the vibration source.
For that goal, a 1-year vibrations monitoring was conducted. The solution included development of a new monitoring system consisting of analog seismometers CME-4211 and geophones MTSS-1001 (R-sensors) and recorders GeoArm-R24 (Arman Fanavaran Zamin also known as Geoarmatech).
The results confirmed feasibility of a new monitoring system which is providing more reliable predictions than those of the FTA direct measurements. The results also showed the water table level has a strong impact on vibrations and accuracy of predictions.
