Description
AG4.5
MidLine 4.5-Hz Seismometer – gimballed
The AG4.5 is ASIR’s readily deployed deep borehole 3-component 4.5-Hz seismometer for use in microearthquake detection and monitoring. It is designed for up to 3000 m depths in NQ 3″ (76 mm) boreholes with tilts of up to 15°. Features the highest current performance level in sensitivity, reliability, and longevity.
Advanced Features
➤ slim 61 mm outer diameter (OD)
➤ passive sensors on damped gimbal
➤ high tilt tolerance of up to 15°
➤ for permanent or temporary installations
Application and Deployment
➤ Small, 6 to 18 station, local monitoring network in up to 3000 m deep, < 15° tilted, boreholes
➤ Station spaced 3 to 5 km apart for event locations to within 100 to 200 meters
➤ Improves detection by 2 units of magnitude over surface networks, detecting and locating all M > ~ -0.5
