International standardization on estimation of geotechnical properties in wide area by microtremor observation


Abstract
NIED has been conducting earthquake prediction map work at the Earthquake Research Promotion Headquarters (hereinafter referred to as "Earthquake Headquarters") of the Ministry of Education, Culture, Sports, Science and Technology since around 2001, and among them, creation of an underground structural model for strong ground motion prediction It has been implemented throughout Japan. Currently, the creation of a ground model has been implemented at SIP (Council for Science and Technology Innovation: Cabinet Office), in which social implementation such as commercialization, commercialization and international standardization is required. Therefore, based on "the concept of underground structural model" released at the earthquake headquarters last year, we have started the international standardization effort on the ground model building method and the microtremor observation carried out therein. Here we report the circumstances of the efforts and the contents of the efforts.
