Event Description

The 8th France-Taiwan Earth Sciences Symposium "Geodynamics and extreme events in Taiwan and South-East Asia" is aimed at fostering exchanges on advanced knowledge, data, methodologies focused on Natural Hazards, Resources, Geophysics & Geodynamics research. Main questions to be addressed by the conference are :

How our advanced knowledge of the deep structure of rifted margins, mountain ranges and subduction zones allows reassessing earthquake-related risks ? How integration of cutting-edge modelling techniques on landscape, climate and tectonic processes improve natural risk assessment and resources exploration  ? Are these knowledges in Taiwan transferrable to other geological settings ?

The Venue : Beaumont Palace - Historic Conference Center, Allée Alfred de Musset, 64000 Pau - France 

Gala dinner : Organised at the Domaine du Cinquau - Chemin Cinquau - 64230 Artiguelouve

Field Trips

Pre-conference field trip

The field trip will explore the Pyrenean geology and put emphases on rift and mountain bulding processes through a selection of stops in France and Spain.

Departure from Pau on October 17th - return to Pau on October 19th. Maximum 30 participants. Provisional excursion directions here. More details on the organisation and fees will be provided soon.

Organisation: Frederic Mouthereau (UPS) and Charles Aubourg (UPPA).

Post-conference field trip

The aim of Alpes/Montagne Noire Field Trip is to compare different structural levels of orogens with Taiwan. 
If the Massif Central part  (South Central Massif, Southern France) will focus on the Montagne Noire, the complete N-S geological section from the Switzerland Jura to Italy through  the major structural domains will be described and commented.

Organisation: Benoit Deffontaines (UPEM), Jacques Malavieille (Univ. Montpellier - Montagne Noire), and Jon Mosar (Freiburg Univ - Alpes).
