• WG1. Seismological Data and Networks

Coordination: Fernando Carrilho, IPMA
Co-coordination: Fernando Borges, UÉ; Nuno Dias, ISEL, Susana Custódio, FCUL
Institutions: FCUL, IPMA, ISEL, UÉ

Working group coordinating the infrastructure for the acquisition and distribution of portuguese seismic data, and for associated products and services.

Aims to requalify the portuguese permanent seismic network, to integrate all permanent seismic stations, to implement an EIDA (European Integration Data Archive) – ORFEUS (European Infrastructure for seismic waveform data in EPOS) node for seismic data distribution, and to operationalize a sharing network of mobile seismic stations.
