| description | Abstract Constructing geotechnical information database to collect information such as geophysical survey results and borehole data and then sharing it among researchers and engineers will be useful for developing research on the subsurface structure and the prevention of disasters such as earthquakes and landslides. The geotechnical information includes analysis results based on geophysical surveys, seismic observations, and borehole data. This database can be visually displayed on a map using a Geographic Information System (GIS). The existing analysis results can be checked consecutively. This will allow us to consider new observation plans and to improve the efficiency and accuracy of the subsurface structure model analysis. Therefore, in this study, a database of geotechnical information was developed for the San’in, Japan region. The San’in, Japan region is the western part of Honshu on the Sea of Japan side and includes Tottori and Shimane prefectures. The database of geotechnical information includes the results of microtremor and gravity survey, estimation of the subsurface structure based on seismic records, and borehole data in Tottori and Shimane prefectures. We gather high dense survey points from multiple references in the San’in region, Japan, such that the average space intervals of single station microtremor, microtremor array, gravity survey, and borehole were around 0.1–1, 1–5, 1, and 0.1–1 km, respectively. Furthermore, the corresponding sites of each survey type were conducted over 6000, over 280, over 7500, and over 3700, respectively. In addition, we developed a system to display the database on a map in a web browser (Web-GIS). GIS, Leaflet, a JavaScript library, were used to display the database of geotechnical information using the Geospatial Information Authority of Japan (GSI) tiled map as the base map. The developed database on the GIS system will be a useful tool that can be used by researchers, engineers, and other stakeholders in the future. Graphical Abstract |
