Broadband Borehole Seismometer – fixed
The ABB is our Broadband 3 component accelerometer with optical interferometer sensors for use in low noise environments. It can be installed in NQ 3″ (76 mm) boreholes with tilts of up to 15°.
Advanced Features
➤ rugged optical sensors with high shock tolerance
➤ active sensors with low power consumption
➤ high tilt tolerance of up to 15°
➤ for permanent or temporary installations
Application and Deployment
➤ On-scale, 20 s to 1200 Hz, local-to-regional earthquake detection and location of M~0 to M~5 EQs
➤ Local and regional networks in up to 1500 m deep, <15° tilted, boreholes spaced 5 to 10 km apart
➤ Improves detection by 2 units of magnitude over surface nets, detecting and locating all M > ~ 0 EQs
➤ Special applications include 4 to 8 station borehole and mine networks for stimulation monitoring
