Stage 3



Mr Thomas Ludwig Hoffmann (CTBTO Preparatory Commission, Vienna, Austria)


The COVID-19 pandemic is a major topic of interest for the SnT2021. The global nature of it produced a resilience test for many, and in particular for a global monitoring system, such as the CTBTO’s, that relies on continuous data gathering, transmission and analysis. The objective of this series of two events is to provide the audience with pertinent case histories and lessons learned from IMS stations e.g. during O&M activities, station upgrades or logistics challenges, faced by the station operators and PTS during the restrictions imposed by covid-19.
Topics presented in Event 1 are (i) the steps taken to ensure operation and maintenance activities for optimal performance of the IMS stations IS32 and PS24 in Kenya during COVID-19 restrictions, (ii) the upgrade of five auxiliary seismic stations in Japan and how the COVID-19 limitations and restrictions were overcome, (iii) restrictions under the COVID-19 crisis imposed on the operation and maintenance of the radionuclide stations RN37 and RN38 in Japan and how JAEA is working with PTS, manufacturers of RASA and SAUNA, and local operators in order to overcome this challenge, (iv) timeline of the active cases at IS42 infrasound station in the Azores, Portugal, the related constraints and O&M actions taken, with PTS support, to guarantee the Mission Capability of the station. (v) CTBTO/OSI will present a brief review of the OSI Training section’s interventions, designed to mitigate the loss of onsite technical training and achieve and maintain true blended learning during and after COVID-19 and (vi) CTBTO IMS/MFS will share examples of logistics and maintenance cases that could have affected data availability and show contingency measures that were implemented.
