Description
AF2
SlimLine 2-Hz Seismometer – fixed
The AF2 is ASIR’s readily deployed shallow borehole / posthole triaxial 2-Hz seismometer for use in micro-earthquake detection and monitoring. It is designed for up to 100 m depths in boreholes as small as 52 mm.
Advanced Features
➤ extra slim 51 mm outer diameter (OD)
➤ passive geophone sensors
➤ for permanent or temporary installations
Application and Deployment
➤ Small, 6 to 18 station, regional monitoring networks in up to 100 m, < 3° tilted, boreholes
➤ Station spaced 4 to 6 km apart for approximate event locations to within 300 to 400 meters
➤ Improves detection by 1 unit of magnitude over surface networks, detecting and locating all M > ~0.5
