Abstract: On 12 January 2010, the devastating Haiti M_W7.1 earthquake occurred on the Enriquillo fault, which broken down the seismic quiescence lasting for about two hundred and forty years, suggesting the beginning of a new active cycle in the Caribbean region. In this paper, we firstly collect the multi-disciplinary results including the tectonic evolution, geophysical field, seismogenic structure, earthquake source physics, kinematic characteristics and stress evolution. Then, we explore the related cognition and its changes on the seismic hazard and others before and after the Haiti earthquake. Finally, we obtain the basic technological process for the seismic hazard analysis, according to the combing and analysis of multi-disciplinary data. Generally, the implementation of work not only provides fundamental reference for the construction of regional dynamic model, but also earthquake prediction in mainland China.
