[MIS10-08] Feasibility Study of Constructing a Seismic Intensity Network in the Southern Hida Mountain Region

Keywords:Hida mountain range, felt earthquake, simple intensity meter

The southern Hida Mountains area frequently experiences active seismic swarms, and many felt earthquakes have been observed. Since here is a steep mountainous area, the seismic observation network is not well developed and it is difficult to obtain detailed official earthquake information quickly. Therefore, when seismicity is active, the unreliable information provided on social networking services (SNS) may cause reputational damage to the tourism industry in the region. In addition, detailed earthquake information is difficult to obtain, which hinders the understanding of hazard information in mountainous areas. As a means of solving these problems, we started a feasibility study of building a seismic intensity network with simple instruments in the region to facilitate rapid information sharing among the stakeholders.
