“…These occurrences potentially stimulate people in low-risk or even safe areas to leave their homes without coordination [167]. This phenomenon can lead to a higher-than-expected number of evacuees [144], which necessitate more evacuation resources.…”

The understanding of evacuation processes is important for improving the effectiveness of evacuation plans in the event of volcanic disasters. In terms of social processes, the enactment of evacuations in volcanic crises depends on the variability of individual/household responses. This variability of population response is related to the uncertainty and unpredictability of the hazard characteristics of volcanoes-specifically, the exact moment at which the eruption occurs (temporal), the magnitude of the eruption and which locations are impacted (spatial). In order to provide enhanced evacuation planning, it is important to recognise the potential problems that emerge during evacuation processes due to such variability. Evacuation simulations are one approach to understanding these processes. However, experimenting with volcanic evacuations in the real world is risky and challenging, and so an agent-based model is proposed to simulate volcanic evacuation. This paper highlights the literature gap for this topic and provides the conceptual design for a simulation using an agent-based model. As an implementation, an initial evacuation model is presented for Mount Merapi in Indonesia, together with potential applications of the model for supporting volcanic evacuation management, discussion of the initial outcomes and suggestions for future work.

“…Numerous issues associated with shadow evacuation can affect the evacuation process. The shadow evacuation was a planning concern in the Houston Metropolitan Region, which greatly restricted the movement of evacuees from high-risk areas (Lamb et al, 2012). In fact, this particular problem was underscored by conditions during and after Hurricane Rita.…”

“…Modeling techniques are similar to those outlined above. Lamb et al (2012) asserted that evacuation efficiency can be achieved in a variety of ways: minimizing the shadow evacuation and background traffic; sheltering victim in place; and phased (staged or sequenced) evacuation. Reducing the magnitude of a shadow evacuation is likely best accomplished through clear communication and education.…”

“…In some areas, over-evacuation of people not threatened directly by a hazard can add to traffic and congestion within a network and hinder the transportation of evacuees who are directly threatened. Lamb et al (2012) identified the factors influencing shadow evacuation. Dependent measures were used to assess the likelihood of a shadow evacuation and identify messages and presenter characteristics.…”
