The AF15 is ASIR’s readily deployed deep borehole 3-component omni-directional 15-Hz seismometer for use in microearthquake detection and monitoring. It is designed for up to 3000 m depths and each component consists of three single sensors in series. Features the highest current performance level in sensitivity, reliability, and longevity.
➤ Deep borehole seismograph for seismicity detection: 1 station for statistics, 4 to 6 for earthquake locations
➤ Deployed in any tilt, 1,000 to 3,000 m boreholes, spaced ~3 to ~6 km apart for ~ 25 to 250 m event location accuracy
➤ Improves detection by 2 to 3 magnitude units over surface stations, covering all M ~ -1.5 within ~3 km radius
