6th Colloquium on historical earthquakes & paleoseismology studies

Their contribution to the knowledge of the long-term seismic activity and to seismic hazard assessment

Location: Han-sur-Lesse (Belgium) - 24-25 October 2018 (google map)
Field trip: on 26 October 2018: Recent tectonic markers in the Han-sur-Lesse and Rochefort caves

Organized by the Royal Observatory of Belgium
Sponsored by the “Domaine des Grottes de Han”, BELSPO and LHOIST.

The colloquium is the 6th of a series that began in 2013 in Paris with the colloquium “Macroseismicity: sharing and use of historical data”. The main topics are: historical earthquakes, macroseismology, archeoseismology, paleoseismology, earthquake catalogues and databases, active faults, seismotectonics, neotectonics, and their contribution to the knowledge of seismic hazard and a better understanding of the long term seismic activity. A specific session will be devoted to earthquake effects in caves.

  • Aurélia Hubert-Ferrari (Université de Liège): Present-day knowledge and questions about seismic versus aseismic activity of the Anatolian Faults in Turkey integrating historical earthquakes, paleoseimic studies and creep evidenced by Insar studies.
