Geoparks are the single, unified, geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development. Dissemination of the local seismicity for public communities is one of our important missions since earthquakes are major natural and cultural heritages in Geoparks.
In July, 2018, National Research Institute for Earth Science and Disaster Resilience (NIED) has opened the web site named as ‘NIED Quake map!’ to visualize the local seismicity around the Itoigawa UNESCO Global Geopark at the Fossa Magna Park (https://www.geopark.bosai.go.jp/itoigawa). It is user-friendly to explore the recent earthquake locations detected by Monitoring of Waves in Land and Seafloor (MOWLAS) and historical earthquakes in the same map. The ‘NIED Quake map!’ shows the seismicity in the wide area around the Geopark. Visitors can access to it by scanning the QR code shown on the information board at the Fossa Magna Park.
A map of the local seismicity during recent one year is shown on the top page of the web site. The color and size of circles indicate the depth and magnitude of earthquakes, respectively. A large star shows the latest earthquake. We also plot volcanoes, active faults, and rivers to grasp the location of the geosite. People can recognize the seismicity within the ground with seeing both memorable large earthquakes and unfelt micro-earthquakes.
Now NIED provides web sites for 16 geoparks among 46 in Japan and plans to open web sites according to their requests by the geoparks through Japan Geopark Network (JGN) based on the Comprehensive Partnership Agreement between NIED and JGN.
The guides of the Geopark use the 'NIED Quake map!' to explain the geology and geophysics at the Geopark. Tourists and school children visiting the Fossa Magna Park access to the web site through the QR code by using their smartphones to recognize both many earthquakes beneath the ground and many earthquakes near the active faults. From 2018 to 2019, we usually confirmed about 20-30 accesses every day and 50-60 accesses by the groups of the field trip at Fossa Magna Park.
NIED supply “NIED Quake Monitor!” for Hakone Geomuseum in Hakone Geopark. This web site shows the waveforms of 10 seismic stations operated by Hot Spring Research Institute of Kanagawa prefecture, JMA, and NIED surrounding the Hakone Geomuseum.
NIED also provides the ‘NIED Quake map!’ for San'in Kaigan UNESCO Global Geopark in 2022. There are approximately 180 elementary, junior high, and high schools in it. They are planning to promote the ‘NIED Quake map!’ to be able to use for teaching and learning tools at schools.
