[MZZ43-P07] Disaster digital archives to be constructed mainly by Geoparks and their challenges
Keywords:2008 Iwate-Miyagi Nairiku Earthquake, Geopark, Traces of Disasters, Disaster Archives, Web-GIS
Since the Great East Japan Earthquake in 2011, efforts have been made to create disaster digital archives (e.g., Tohoku University's "Michinoku Shinrokuden"). In Choshi Geopark, a digital archive is available to the public. Efforts are also being made to combine map information with traces of disasters. For example, Suzuki and Sato (2022) conducted an initiative in the Bandaisan area using disaster traces and photo content related to the 1888 Bandaisan eruption. In addition, the National Research Institute for Earth Science and Disaster Prevention (NIED) and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) are taking the lead in releasing digital archive maps of disaster monuments.
Kurikoma-sanroku Geopark was established after the Iwate-Miyagi Nairiku Earthquake of 2008 (hereinafter referred to as "the 2008 earthquake"), and also serves as a disaster archive of the 2008 earthquake. Fifteen years have passed since the earthquake, and many of the traces of the disaster site are no longer visible, and the succession of information on the occurrence of the disaster is becoming less and less important. Therefore, the disaster traces and materials that have been accumulated in the Geopark will be disseminated as comprehensive contents that look at the entire region using Web-GIS technology.
The composition of contents is assumed to be about six items, referring to Suzuki and Sato (2022): a) geo-sites, b) monuments for natural disaster transmission, c) materials on the 2008 earthquake phenomenon, d) photos from that time, e) local disaster prevention activities, and f) past natural disasters that have occurred in Kurihara City.
The digital archive will be used for geoguide and professional geopark research; the GIS platform will be open source and the disaster archiving system will be from stakeholder organizations.
The issues are to examine the attribute information required for the Geopark, to specify the source of the data, and to develop the underlying phenomenon information data. We will continue to select open or closed information, to grant permission for secondary use, and to survey the current status of the natural disaster tradition monuments and sunken bridges in the area.
