  1. 14:00-14:15


TITLE: Relative sea-level changes recorded by coral microatolls, implications for Lesser Antilles megathrust seismic behavior


AUTHOR: * Jennifer WEIL-ACCARDO (ERI), Nathalie FEUILLET (IPGP)・Eric JACQUES (IPGP), Pierre DESCHAMPS (CEREGE), François BEAUDUCEL (IPGP)・Jean-Marie SAUREL (IPGP), John GALETZKA (CALTECH), Paul TAPPONNIER (EOS)


SUMMARY: By using coral microatolls we reconstructed relative sea-level changes in Martinique and Guadeloupe over the last two centuries, which allow us to discuss implications for the megathrust seismic behavior at the secular scale.
