We propose to continue our paleoseismological and multi-lateral, international collaborations on active fault behaviors in Myanmar. In 2018, our three major goals are to (1) continue paleoseismological investigations of the central Sagaing fault by analysis of airborne LiDAR and UAV surveys and... Read more

Earthquake recurrence models are important to assess seismic hazard but remain poorly constrained due to insufficient of data. In order to assess which model is most useful, we study the exceptionally well-preserved archive of earthquake ruptures along the eastern Altyn Tagh fault (China). We... Read more

The Mentawai Gap–Tsunami Earthquake Risk Assessment (MEGA-TERA) is a joint project between Schmidt Ocean Institute (SOI), the Earth Observatory of Singapore (EOS), the Indonesian Institute of Sciences (LIPI) and the Institut de Physique du Globe de Paris (IPGP). Seismic reflection, bathymetry,... Read more

Since the advent of plate tectonics, modelling the deformation of continents (particularly the nucleation, growth and interaction of large faults) has been plagued by drastic shortcomings. Dynamic scaling is difficult or impossible with analogue models, while numerical models yield results that... Read more

Slip-distributions along earthquake ruptures provide essential information to understand seismic fault behaviour, but remain poorly constrained on most faults. EOS augments the global co-seismic slip database by exploiting the exceptional archive of well-preserved... Read more

One major issue addressed here is to know whether the recent great earthquakes on the MFT ruptured the surface or not. EOS confirmed with 14C dating that the rupture of the 1934 Bihar-Nepal earthquake (Mw 8.2) reached the surface. It is a major breakthrough as the hitherto entrenched consensus... Read more
