Research and development on improving the ability to predict, prevent, and respond to volcanic hazards
Reduction of volcanic hazards with the power of science and technology
Volcanoes bring us benefits through tourism and hot springs, but they also sometimes bring disasters that can cause long-term inconvenience to residents living at the foot of the mountains. A resilient society against volcanic disasters is one that can use volcanoes safely by knowing the risks associated with volcanic disasters and taking appropriate measures in response to changes in volcanic activity and its threats. We will promote research on improving the ability to predict, prevent, and respond to volcanic disasters in order to achieve a resilient society.
Development of technology for predicting volcanic activity
Volcanic activity causes various phenomena such as earthquakes, crustal deformation, volcanic gas emissions, and eruptions. We will develop predicting technology for volcanic activity by utilizing data from the Fundamental Volcano Observation Network (V-net), remote sensing technology, and material science surveys. In addition to research on individual volcanic phenomena, we will improve our predicting capabilities by, for example, conducting research on the prediction of volcanic activity transitions based on the "state of volcanic activity," a comprehensive view of volcanic activity using various types of data.
Promotion of data and knowledge integration
Various data and simulation results of pyroclastic flows and lava flows are integrated into the JVDN (Japan Volcanological Data Network) system. Furthermore, we will promote the integration of knowledge in the field of volcanoes through the JVDN system and the state of volcanic activities. By changing the state of society (e.g., exposure state) in response to changes in the state of volcanic activity, the threat and risk of eruptions can be weakened or reduced (Figure). We will promote research to improve preventative capability through clarifying the relationship between the state of volcanic activity and the state of society by also utilizing social data such as exposure and vulnerability information.
Disaster response
It is difficult to accurately predict ashfall and lava flows in advance because they vary greatly depending on wind direction and topography. Therefore, it is necessary to collect information quickly after an eruption occurs and provide it to administrative agencies. Under the policy of the Cabinet Office, a system has been established to collect and promptly share ashfall survey data using the JVDN system. Utilizing this mechanism and others, we will promote research to provide information products that can be used for decision-making during disasters in order to improve response capabilities.
Strengthening of cooperation
In order to realize a resilient society against volcanic disasters, it is necessary to integrate various research fields that focus on volcanoes and strengthen cooperation among organizations involved in research and disaster risk reduction. As a core research institute for disaster risk reduction science and technology, NIED will contribute to strengthening collaboration through the JVDN system and other means.
