Overview The IOC-UNESCO Intergovernmental Coordination Group of the Pacific Tsunami Warning and Mitigation System (ICG/PTWS) Working Group 2 – Tsunami Detection, Warning and Dissemination; Task Team on Seismic Data Sharing in the Southwest Pacific met in March 2019 in Noumea, New Caledonia following the 5th Oceanic Regional Seismic Network (ORSNET) member states meeting and made recommendations to the 28th ICG/PTWS meeting held in Managua Nicaragua in April 2019; • The ORSNET member countries recognize the need for regular capacity building through work attachments, knowledge and expertise transfer among member countries; and • The ORSNET member countries agreed that ORSNET should be regionally aligned for long term sustainability. These recommendations led IOC-UNESCO to coordinate with ORSNET secretariat, Vanuatu Meteorology and Geohazard Department (VMGD) in engaging The Pacific Community (SPC) Pacific Resilience Program (PREP) project to support one participant from each ORSNET member states to attend the Basic SeisComp Training delivered online by Gempa. The objective of the SPC PREP project is to strengthen early warning, resilient investments and financial protection of participating countries. SPC PREP project support towards this Online Basic SeisComp Training strengthens early warning for earthquakes and tsunami in the Southwest Pacific. The Gempa Basic SeisComP online training will be conducted from 26th -30th October and 2nd -4th November, 2020.This training is intended to enable participants to have a better understanding of the following; • Characteristics of SeisComP; • Latest SeisComP release and future updates installed; • Generation of station information including responses; • Setup of the data acquisition, storage and distribution using seedlink, archlink or FDSNWS • Configuration of the automatic and interactive data processing modules through the new graphical user interface. • Data management utilities • Tuning of SeisComP for local, regional and global earthquake monitoring including phase pickers, locator, associator and magnitudes; • Practical training (focusing on real-time playbacks, off-line playbacks and hands-on tuning. • Familiarization on use of own datasets for tuning.
