Description
Triaxial Seismic Monitors Earthquake Recording Instrumentation (ERI) Strong Motion Accelerograph  

Seismic monitoring systems provide valuable data and information on the behavior of buildings leading to improved understanding and better design codes. For these reasons, many municipalities (e.g., City of Los Angeles, CA USA, Philippines and the Department of Public Works and Highways (DPWH) ) require seismic instrumentation or offer benefits such as reduced inspection time as part of a building occupancy resumption program.


Why need Strong Motion Accelerograph on buildings and construction?

1. Free site strong earthquake observation;

2. Strong vibration view of important buildings, structures and major facilities such as hydropower stations, DAMS and nuclear power plants
Measurement and health monitoring;

3. Artificial blasting observation;

4. Vibration monitoring of DAMS, Bridges, stations, tunnels and other facilities;

5. Site seismic safety assessment, etc.;

6. Emergency flow seismic observation, earthquake scientific investigation, earthquake early warning and monitoring, landslide and rock fall monitoring;

7. Build an earthquake intensity quick report and earthquake early warning network;

8. Cultural relic preventive protection and cultural relic facility environmental monitoring system.


How to install Strong Motion Accelerograph?

For buildings with 3 or more accelerographs, the instruments must be networked together so that they can function in unison. The instruments should be located in the following areas:

Ground floor or lowest basement
Middle floor
Floor below the roof
This allows the instruments to record the right information of how a building responds when a major earthquake occurs.
