Volcano hazard maps show the geographic distribution of volcanic hazards in the foothills, and the type and magnitude of possible hazardous phenomena in a given section. However, during a real eruption crisis, it is necessary to consider actions and preparedness at each point in time. Such a time series of situation transition and response is sometimes referred to as a "timeline".
Compared to other natural hazards such as typhoons, volcanic eruption scenarios are more diverse and variable, and it is generally difficult to imagine a timeline for an eruption crisis. However, in many cases, actual evacuation and erosion control plans for volcanoes describe timelines that assume eruption size, eruption style, and a simple increase in hazard level to an eruption. Because such a scenario is one of many possible scenarios, deviations from the real situation could lead to confusion and delays in response.
Based on this awareness of the above problem, the author attempted to generalize variable eruption scenarios of Fuji Volcano, typify disaster cases and responses at a business site at the foot of the mountain, and provide a timeline as a basis for a business continuity plan.
