Station Information
Location: Mirador (lookout point), Poas volcano, Costa Rica Installation Date: February 2024 (AVERT field workshop) Instrumentation:- MEMS-based Wee-g micro-gravimeter (University of Glasgow)
- Continuous data output via serial communication interface
- Integrated into the AVERT node control software
- First continuous MEMS gravimeter deployed on any volcano worldwide
- Complements GNSS and gas observations to constrain processes in the hydrothermal system and shallow magmatic reservoir
- Serves as a test of the AVERT platform’s extensibility to new sensor types
- Hub station for the Poas AVERT network
- Co-located with Starlink satellite telemetry, weather station, infrared camera, and web camera
- Equipped with a larger power system (300 W solar panel, 2-4 x 100 Ah batteries) to support the full suite of instruments and telemetry
- Gravimetric data currently archived at LDEO, being transferred to the University of Glasgow for processing
