Geoparks are UNESCO programs that promote sustainable development of areas with geologically valuable sites and landscapes through conservation, education, and geo-tourism activities. One of the characteristics of Japanese geoparks is that the entire Japanese Islands are located in the mobile belt, and many geoparks have the theme of "Moving Earth." Active faults, along with active volcanoes, symbolize the movements of the ground in the Japanese Islands, and it is of great significance for researchers of active faults to support geopark activities. In the present study, we reported the results of the questionnaire survey conducted by the Committee on Education and Outreach of the Japanese Society for Active Fault Studies to consider future policies for support for Japanese geoparks.
The questionnaire survey was conducted in 44 certificated geoparks and 12 associate members. The response rate was 66% (37 out of 56 areas) for all and 73% (32 out of 44 areas) for the certificated geoparks.
As a result, we found that about 41% of the geoparks use active faults as geosites, and about 62% of the geoparks explain active faults in some way. In addition, it was found that about 81% of the geoparks have been working on disaster prevention against earthquakes and active faults. On the other hand, there are some geoparks where active faults are distributed within the area but are not utilized as geosites, and the most common reason for this is that there are no appropriate observation sites. For these geoparks, support by experts of active faults is considered necessary.
