Description: Full integration of new data types into Indonesian Tsunami Early Warning System (InaTEWS) is among the enhancements being pursued at BMKG. Leveraging on external projects and partnership Real-Time Precise Point Positioning (RT-PPP) data from BIG have been integrated in the processing chain at BMKG. This GNSS data product has the potential contribute to faster and more accurate scenario selection and validation in case of large tsunamigenic events. Real-time waveforms displacement obtained with the method of Precise Point Positioning with Regional Augmentation correction (PPP-RA) and Precise Point Positioning with Ambiguity Resolution of the RT-PPP-Client, is thus acquired in SeisComP via a dedicated seedlink plugin developed within the project of Early Warning and Rapid ImpaCt Assessment (EWRICA) in the Mediterranean. Once integrated into SeisComP precise point positioning time series are integrated into the processing pipeline of the BMKG. We have successfully integrated RT-PPP processed by Geospatial Information Agency (BIG) into InaTEWS which is managed by the Meteorological, Climatological, and Geophysical Agency (BMKG). Next, waveforms will be used to improve and speed-up the earthquake parameter determination for large tsunamigenic events.

Description: Interoperability of data and products among disciplines is becoming a key aspect within the scientific community to allow the optimal integrated exploitation of data, taking advantage of modern real-time work-flows using also AI techniques.Within the EWRICA project, aiming at creating robust local ground motion models shortly after an earthquake to assess secondary effects such as tsunamis and landslides, one of the tasks focussed on integration of near-field seismo-geodetic data into real-time source inversion. To enable this task, Real-Time Precise Point Positioning (RT-PPP) data have been converted to miniSEED records on the fly by using a tailored plugin for SeisComP developed within the project. The real-time data in GFZ Displacement Real-Time (GDRT) format have been mapped to miniSEED channels as described in the SeisComP documentation [1]. The initial mapping has been defined considering also one additional use case implemented in the TURNkey project where RT-PPP data were generated from a newly developed standalone instrument. RT-PPP has been integrated in the data flow and sent out to clients via seedlink for processing in the known data and metadata format enabling faster and improved assessment of seismic moment, hypocentre and rupture kinematics.In this presentation we introduce the gdrt_plugin released for the first time in June 2022 with the SeisComP v5.0.0 [2], we outline the initial process of mapping the GNSS products to existing data and metadata formats and would welcome discussions about further integration in seismology through the FDSN.[1] https://www.seiscomp.de/doc/apps/seedlink.html#seedlink-sources-gdrt-label[2] https://github.com/SeisComP/seiscomp/releases/tag/5.0.0
