The system built is based on comprehensive research, through a multi-method approach, including the study of volcano geology, seismicity, deformation, which can be updated automatically based on long-term and short-term assessments, which will then be included in the information system in the form of an online (digital) service product, in the form of a webgis that allows users to easily obtain volcanic hazard assessment data, is flexible, easily accessible anywhere and anytime, and free of charge.
