Earthquake recurrence models are important to assess seismic hazard but remain poorly constrained due to the scarcity of data.
Prof. Paul Tapponnier’s team is interested in continental dynamics and tectonics, particularly in Asia (from Myanmar to Mongolia) but also in the Middle-East (in Lebanon and around the Red Sea). Paul Tapponnier and his team investigate active faulting and seismotectonics and assess earthquake hazard by using quantitative geomorphology, rock mechanics and rock deformation physics.
The Mentawai Gap–Tsunami Earthquake Risk Assessment is a joint project between Schmidt Ocean Institute, the Earth Observatory of Singapore, the Indonesian Institute of Sciences, and the Institut de Physique du Globe de Paris.
Tapponnier and his team are searching for past earthquakes in Nepal to determine what kinds of earthquakes may threaten Kathmandu in the next decades.
The largest earthquake ever recorded in an ocean happened in 2012 in the Indian Ocean; yet even with modern instruments, scientists have debated how this rupture occurred. This project will use new datasets to fully understand this earthquake....
Tapponnier and his team are implementing an innovative 3D model to simulate different types of faults. They will continually refine the model to more precisely describe the formation and evolution of large faults.
Slip-distributions along earthquake ruptures provide essential information to understand seismic fault behaviour, but remain poorly constrained on most faults.
