Development of a decision support system for tsunami evacuation: application to the Jiyang District of Sanya city in China

Abstract

Abstract. Major tsunami disasters often cause great damage in the first few hours following an earthquake. The possible severity of such events requires preparations to prevent tsunami disasters or mitigate them. This paper is an attempt to develop a decision support system for rapid tsunami evacuation for local decision makers. Based on the numerical results database of tsunami disasters, this system can quickly obtain the tsunami inundation and travel time. Because numerical models are calculated in advance, this system can reduce decision-making time. Population distribution, as a vulnerability factor, was analyzed to identify areas of high risk for tsunami disasters. Combined with spatial data, this system can comprehensively analyze the dynamic and static evacuation process and identify problems that negatively impact evacuation, thus supporting the decision-making for tsunami evacuation in high-risk areas. When an earthquake and tsunami occur, this system can rapidly obtain the tsunami inundation and travel time and provide information to assist with tsunami evacuation operations.

A Review of Historical Volcanic Tsunamis: A New Scheme for a Volcanic Tsunami Monitoring System

“…The wave periods of volcanic tsunamis are usually several minutes. However, the wave periods of seismogenic tsunamis are larger, about tens or even hundreds of minutes [33]. Thus, compared with tsunamis triggered by earthquakes, tsunamis associated with volcanic activities have the characteristics of relatively short periods, large dispersion and a limited propagation range [34,35], unless there is a giant flank collapse landslide or explosive volcanic eruption [31].…”

The Use of Geospatial Information by Public Authorities to Support the Decision Making of Management

“…Databases are a collection of geospatial data, defined calculations and studies. Knowledge bases contain inference rules, information about human experience and knowledge in a given subject area, which allow you to perform operations on these databases [10].…”

Use of Geospatial Information for Decision-Making in Environmental Monitoring of Temporarily Occupied Territories

“…Thus, decision support systems, collecting and analyzing a sufficiently large amount of information from the temporarily occupied territories, can influence the process of making managerial decisions. With the help of decision support systems, the choice of solutions can be carried out in poorly structured and certain unstructured tasks or in tasks that have many criteria 7 .…”
