The Institute of Geophysics (IGP), VAST together with the Institute of geological and Nuclear Science from New Zealand (GNS Science), to conduct research project "Tsunami hazard, Risk and preparedness assessment for Vietnam". The Project has being support and funding by Agency for International Development of New Zealand (NZAID) and VAST andfor Implementation in 2007-2009 years. The paper introduces the main outcomes of collaboration project in different fields as : Specialists exchange, experience share, conduct of scientific conferences, workshops, training courses for young specialist, technological transfer of earthquake and Tsunami hazard evaluation and warning to scientists and specialists of IGP, other institutions and universities as well as some localities in coastal areas of Vietnam.
