Preface: “Improving seismic networks performances: from site selection to data integration (EGU2019 SM5.2 session)”

The number and quality of seismic stations and networks in Europe continually improves, nevertheless there is always scope to optimize their performance. In this EGU2019 SM5.2/GI4.13 session we welcomed contributions from all aspects of seismic network installation, operation and management. This includes site selection; equipment testing and installation; planning and implementing communication paths; policies for redundancy in data acquisition, processing and archiving; and integration of different data sets including GPS and OBS.

1 Introduction

The history of seismic networks sessions at European Geosciences Union (EGU) general assemblies started in 2010 with the SM1.3 “Seismic Centres Data Acquisition” session (Pesaresi, 2011), where the convener Damiano Pesaresi supported by the Orfeus Data Centre (ODC) Director co-convener Reinoud Sleeman chaired a session of 7 oral and 16 poster presentations. Later in the same year a similar session was held at the XXXII European Seismological Commission (ESC) General Assembly: “SD1, 3 Seismic centres data acquisition”, conveners Damiano Pesaresi and Reinoud Sleeman, with 15 oral presentations.

The history of these sessions continued in 2011 with the EGU2011 SM1.3/G3.8/GD3.7/GI-19/TS8.7 “Improving seismic networks performances: from site selection to data integration” session (EGU2011, 2011), where the convener Damiano Pesaresi supported by the co-conveners John Clinton and Robert Busby chaired a session of 9 oral and 20 poster presentations; in 2012 with the EGU2012 SM1.3/GI1.7 “Improving seismic networks performances: from site selection to data integration” session (Pesaresi and Vernon, 2013), where the convener Damiano Pesaresi supported by the co-convener Frank Vernon chaired a session of 6 oral and 22 poster presentations; in 2013 with the SM1.4/GI1.6 “Improving seismic networks performances: from site selection to data integration” session (Pesaresi and Busby, 2013), where the convener Damiano Pesaresi supported by the co-convener Robert Busby chaired a session of 6 oral and 13 poster presentations; in 2014 with the EGU2014 SM1.2/GI3.7 “Improving seismic networks performances: from site selection to data integration” session (Pesaresi et al., 2015), where the convener Damiano Pesaresi supported by the co-conveners John Clinton and Helle Pedersen chaired a session of 12 oral and 27 poster presentations; in 2015 with the EGU2015 SM1.2/GI1.5 “Improving seismic networks performances: from site selection to data integration” session (EGU2015, 2015), where the convener Damiano Pesaresi supported by the co-conveners Helle Pedersen and Yuri Starovoit chaired a session of 20 poster presentations; in 2016 with the EGU2016 SM7.3 “Improving seismic networks performances: from site selection to data integration” session (EGU2016, 2016), where the convener Damiano Pesaresi supported by the co-conveners Helle Pedersen and John Clinton chaired a session of 6 oral and 16 poster presentations; in 2017 with the EGU2017 SM5.3 “Improving seismic networks performances: from site selection to data integration” session (EGU2017, 2017), where the convener Damiano Pesaresi supported by the co-conveners Helle Pedersen and Christos Evangelidis chaired a session of 15 poster presentations; and in 2018 with the EGU2018 SM5.01/NH4.16 “Ground translation, strain and rotation: New and improved instrumentation and applications” session (EGU2018, 2018), where the convener André Gebauer supported by the co-conveners Helle Pedersen, Angelo Strollo, Damiano Pesaresi, Christian Schubert, Stephanie Durand, and Stefanie Donner chaired a session of 12 oral and 27 poster presentations.

2 The EGU2019 SM5.2/GI4.13 “Seismic Networks” session

In the EGU2019 SM5.2/GI4.13 “Improving seismic networks performances: from site selection to data integration” session (EGU2019, 2019) the convener Damiano Pesaresi supported by the co-conveners Helle Pedersen and Angelo Strollo chaired a session (Fig. 1) of 7 orals (Table 1) and 17 posters (Table 2) presentations.

The 24 presentations came from 15 countries (China, Turkey, France, The Netherlands, Taiwan, Russia, USA, Austria, Italy, Canada, Switzerland, United Kingdom, Romania, Spain, Mexico), in 3 continents (Asia, Europe, North America), which fits well to the goals of the European Geosciences Union.

The solicited presentations in this session were the following:

• i.

  “New federated seismological services within EIDA”, by Javier Quinteros, Daniel Armbruster, Massimo Fares, Stefan Heimers, Andres Heinloo, Mathias Hoffmann, Philippe Kaestli, Mathijs Koymans, Erich O. Muhire, Cristian Neagoe, Mehmet Ozer, Catherine Pequegnat, Jonathan Schaeffer, Luca Trani, and Nikolaos Triantafyllis (Quinteros et al., 2019);

• ii.

  “Quality Improvement of the French Permanent Broadband Stations with Shallow Posthole Installations”, by Jérôme Vergne, Hélène Pauchet, Mickaël Bonnin and the RESIF-CLB Team (Vergne et al., 2019).

3 Conclusions

The quality and quantity of presentations made at the EGU2019 SM5.2/GI4.13 session satisfied the expectations of the convener and co-conveners and fit the goals of the European Geosciences Union.

This year the number of presentations at the seismic networks session increased: therefore the conveners after so many years are still confident that the path they followed in organizing such sessions at the yearly EGU General Assembly is a valid one, since there is a clear benefit in the seismological community worldwide to present and discuss different solutions to common problems in running seismic networks.
