Standard Format of Microtremor Data, and Microtremor Database System.


Abstract
We have developed an Integrated Geophysical and Geological Information Database to support researches on earthquake disaster mitigation since 2003. In this study, the collection and the arrangement of data concerning the microtremor measurement were done among those data as the examination concerning the display of information including making to the database and the microtremor data. Data concerning the microtremor is data of about 48000 points acquired in K-NET etc. As information, it is Fourier spectrum, H/V spectrum, and a photograph records. The format of the speed structure of S wave was decided referring to a past thesis, and data was made. The application version can inspect data and other information (geological and geographical data) on the microtremor data at the same time. This application can confirm various information with the notebook computer etc. easily and promptly in the field investigation etc. Moreover, there is 'Easy database function' that can register investigation information on microtremor data.
