Over 90% of natural disasters have occurred in Asia and millions of people have lost their lives and homes by the recent earthquakes, tsunami and natural disasters. Earthquake prediction is not available in short-term, however, Probabilistic Seismic Hazard Assessment (PSHA) in long-term is considered as a scientific way to define earthquake area/zones and to guide urban planning and engineering management.
A strategic cooperative program (2010-2013) of "Seismic Hazard Assessment for the Next Generation Map" was finally selected after individual examinations by committees of MOST, NRF and JST, in China, Korea and Japan, respectively. The goal of this strategic project is to improve the PSHA methodology for the next generation maps in the three countries. To achieve this goal, the following approaches are planned:
to review the data and the methodologies adopted in the current PSHA maps of the three countries and evaluate if there is anything to be improved or added in each of the countries;
to compare the data and the methodologies with the state of the art technology and see if anything could be accepted for the next generation maps;
to develop a procedure to establish ground motion attenuation relationships for the maps;
to combine the probabilistic seismic hazard assessment and the deterministic approach of scenario earthquake for potential large earthquake and to prepare an example map for each country.
This site is a communication forum to deal with theories, methodologies, data and related issues. We encourage people from all of over world to exchange their own experiences and individual methods.
