T4.2 Systems Engineering for International Monitoring System and On-Site Inspection

Oral

The geophysical instrumentation of the CTBT worldwide is important for characterizing nuclear and chemical tests. These observatories have also strengthened the geophysical monitoring capabilities of solid-earth processes like large earthquakes and volcanic eruptions on Earth. However, assuring the correct functioning of this instrumentation is hard under extreme conditions of temperature,...

731. Evaluation and Resolution of Identified Issues at CTBTO Auxiliary Seismic Stations in Indonesia Based on Incidents Reported over the last five Years (O4.2-731)

Mr Destiawan Kriswibowo (PT. Mindotama Avia Teknik)

T4.2 Systems Engineering for International Monitoring System and On-Site Inspection

Oral

In Indonesia, the CTBTO auxiliary seismic station network consists of one data center (NDC-BMKG) and six auxiliary seismic stations. Each station is in a different environmental condition and faces a unique set of troubleshooting challenges. According to the incident's history over the last five years, power and on-site communication issues were prevalent. The implemented troubleshooting is...

90. Optical Fiber Sensor Based Transportable Active Seismic Survey System Solution to On-Site Inspection (O4.2-090)

Mr Qin Li (Television & Electroacoustic Research Institute)

6/21/23, 5:30 PM

T4.2 Systems Engineering for International Monitoring System and On-Site Inspection

Oral

Active seismic survey, together with aftershock seismic survey, magnetic and gravitational field mapping and electrical conductivity measurements (Protocol to the CTBT, Part II), are geophysical detection technology which can contribute jointly to the search logic for the detection of on-site inspection (OSI) anomalies or artifacts underground. This work presents a system solution to active...
