Projet SUPNAF : Sismicité de la faille Nord-Anatolienne, Turquie

Michel BOUCHON — 2025-09-05T13:50:59Z

Liens entre complexité de la faille, essaimage de la sismicité et
vitesse de rupture : l'importance de l'étude de la Faille Nord
Anatolienne

Durée : 2009 - 2012
Coordinateur : Jean Schmittbuhl (Institut de Physique du Globe de Strasbourg)
Contact à ISTerre : Michel Bouchon
Participation de l'équipe Mécanique des failles
Collaborations extérieures :
– IPGS
– BRGM

Existe-t-il deux types de faille : l'une ayant une structure simple (peu ramifiée, segments linéaires), présentant peu de sismicité hormis au voisinage de la zone de nucléation (précurseurs) et une propagation supershear de la rupture avec possibilité de partionnement du déplacement, l'autre ayant une structure complexe (multi-échelle), beaucoup de sismicité (en particulier des répliques) et une propagation de la rupture sub-Rayleigh ?

Voici le problème qu'il est proposé de traiter dans ce projet en prenant pour objet d'étude l'un des meilleurs sites possibles : la partie occidentale de la faille nord Anatolienne (de la mer de Marmara à la région d'Izmit-Duzce, épicentres des séismes de 1999). Ce site a été très largement étudié et donc beaucoup d'informations sont disponibles. Il existe un réseau sismologique à terre très dense et des campagnes d'OBS en mer soit récemment effectuée soit en projet. Deux très grands événements s'y sont produits récemment, fournissant des jeux de données tout à fait uniques. L'enjeu reste considérable puisque la ville d'Istanbul est particulièrement menacée.

SUPNAF project : Seismicity of the North Anatolian Fault, Turkey

Anaïs SCHNEIDER, Michel BOUCHON — 2009-09-26T07:15:00Z

Links between fault complexity, seismicity swarming and
failure rate : the importance of the study of the North Fault
Anatolian woman

Are there two types of fault : one with a simple structure (unbranched, linear segments), with little seismicity except in the vicinity of the nucleation zone (precursors) and a supershear propagation of the failure with the possibility of partitioning the displacement, the other with a complex structure (multi-scale), much seismicity (especially replicas) and a propagation of the sub-Rayleigh failure ?

This is the problem that is proposed to be addressed in this project by studying one of the best possible sites : the western part of the northern Anatolian fault (from the Marmara Sea to the Izmit-Duzce region, epicentres of the 1999 earthquakes). This site has been very extensively studied and therefore a lot of information is available. There is a very dense seismological network on land and OBS campaigns at sea either recently carried out or planned. Two very large events have occurred recently, providing unique datasets. The stakes remain high since the city of Istanbul is particularly threatened.
