Description
The ASF056 auxiliary station borehole seismometer was malfunctioning, and the local operator in the State Party lacked the financial resources to cover the costs of replacing and upgrading the outdated equipment. Through the efforts of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) and the Jordan Permanent Mission, the European Union (EU) provided a significant donation to support the replacement and upgrade of the ASF056 station seismometer. Borehole seismometers are a critical tool for detecting seismic events with high precision, and this upgrade will enable more accurate analysis of local seismic activity and the International Monitoring System. The mission was executed by the ASF station operators, the CTBTO team, and technicians from the seismometer manufacturing company. The objectives of the mission were as follows: a. recover and decommission the existing Guralp equipment (borehole seismometer and digitizer), completed by the Jordan Seismological Observatory staff; b. deploy nanometrics equipment from SO59480, including the Trillium 120 Borehole Seismometer (T120-BH2-2000), Centaur Digital Recorder CTR4-3A, GPS antenna, and vault tamper switch; c. Perform borehole sensor orientation analysis using a reference sensor.
