On June 16th a TCS-AH half day online workshop took place entitled ‘TCS AH Research Infrastructures and Use Cases for and by the Induced Seismicity Community’. The event involved ~40 participants and began with Ania Lesnodorska from the hosting institution (IG PAS) delivering an overview of the TCS including it’s history, formation, technical facilities and consortium partners. This was followed by a presentation from Mieszko Makuch (ACC Cyfronet AGH) on the status of the IS-EPOS Platform and recent developments including the major new functionalities of the AH research infrastructure.
EPOS’s ICS-C (Integrated Core Service – Central) and the integration of the AH Infrastructure (the IS-EPOS Platform) was then presented by Kuvvet Atakan (UiB).
The second half of the workshop focused on TCS AH research infrastructure use case examples and covered:
- Public engagement potential through visualisations of Episode Data (Ian Stimpson, KU)
- Seismic moment evolution during hydraulic stimulations (Grzegorz Kwiatek, GFZ)
- Completeness magnitude estimation of an induced seismic catalog (Kamel Drif, UNISTRA/EOST)
- The use of data and software tools for induced seismicity research (Alexander Garcia, INGV).
Sessions were followed by Q&A and open discussion and highlighted the definition, novelty and importance of datasets packaged as ‘Episodes’ (i.e. a set of time-correlated data and data products grouped together to facilitate the correlation and analysis of anthropogenically induced or triggered processes and hazards).
Overall, the workshop struck a great balance in providing attendees with a well structured and diverse mix of sessions and content to learn about the TCS and EPOS in general, whilst also demonstrating how the TCS-AH could be utilised for induced seismicity research AND also for capturing greater public attention through the assimilation of Episode data into art!
Following the workshop, a 2 hour online training session on the IS-EPOS platform took place on the 17th June with 18 participants. Michal Lelonek of IG PAS presented the platform by showcasing Episode data from across four continents and four different industries. The first presented episode was Asfordby, related to the no longer operating coal mine in Great Britain. The next episode, Australian Cooper Basin, related to a geothermal hydraulic stimulation was used to show data visualization methods. The relationship between injection rate and seismic activity was also presented. Then, the continent was changed to North America and, based on the episode of Oklahoma associated with conventional and unconventional hydrocarbon extraction, where the “Catalog Filter” application was discussed. The last episode presented was the Vietnamese Song Tranh, related to a reservoir impoundment. The episode was used to present slightly more advanced applications: spectral analysis and FOCI – an application for resolving seismic moment tensors. Workshop participants could also observe how the P and S waves are picked, as well as methods to load their own data sets into the workspace.
The training event provided a great introductory step towards more advanced training series to be happening in the future!
