  Title Evaluation of Improvement Projects in Densely Built-Up Area using a Large Earthquake Disaster Simulator: A case study in Kyojima Area, Tokyo Type Conference Article
  Year 2023 Publication Proceedings of the 20th International ISCRAM Conference Abbreviated Journal Iscram 2023  
  Volume Issue Pages 546-564  
  Keywords Urban Planning; Policy-Making; Large Earthquake; Disaster Mitigation; Improvement Project; simulation  
  Abstract This paper aims to (1) evaluate the disaster mitigation effects of improvement projects in a certain area and (2) provide a basis for strategic planning to promote further improvements. Specifically, we decompose local improvements in the analyzed area into multiple scenarios and examine their effects and issues. First, we describe the “large earthquake disaster simulator,” which estimates property damage and human casualties in a large earthquake. Then, the Kyojima area of Sumida-Ku, Tokyo, is selected as the analyzed area. We decompose the improvement projects implemented during 2006 – 2016 and prepare six scenarios. Finally, a simulation analysis is conducted. We demonstrate that fire spread could be effectively blocked by (1) ensuring sufficient road width and (2) identifying the critical buildings in terms of fire spread mitigation and making them fireproof.

  Title Accessibility Assessment of Vulnerable Roadside Areas after a Major Earthquake Type Conference Article
  Year 2021 Publication ISCRAM 2021 Conference Proceedings – 18th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal Iscram 2021  
  Volume Issue Pages 553-566  
  Keywords Large earthquake, accessibility assessment, emergency activity, building collapse, road blockage  
  Abstract In order to reduce human casualty after a large earthquake, it is vital to secure the traffic function of main roads. Local governments promote the seismic reinforcement of roadside buildings, however, the project is not going well as planned. There is a high demand for appropriate information of its effect. In this paper, we proposed a method to identify the roadside areas with vulnerable accessibility to disaster bases after a large earthquake. First, we defined the accessibility indices; Link Isolation ratio (LI ratio) and Network Isolation ratio (NI ratio). Then, using the simulation model, we evaluated the accessibility to disaster base hospitals using emergency transportation roads in the Tokyo Metropolitan Area. LI ratio tended to be low in areas with a sparse road network. Furthermore, some hospitals indicated a severely high NI ratio. In secondary medical areas with these hospitals, it is necessary to consider the measures to improve accessibility.

  Title Wide-area Evacuation Difficulty in Densely-built Wooden Residential Areas Type Conference Article
  Year 2016 Publication ISCRAM 2016 Conference Proceedings ? 13th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2016  
  Volume Issue Pages  
  Keywords Large Earthquake; Wide-area Evacuation Difficulty; Property Damage; Multi-Agent Simulation; Densely-built Wooden Residential Area  
  Abstract In aiming to decrease the number of casualties and people with difficulty in wide-area evacuations due to a large earthquake, it is highly important to visualize and quantify the potential danger in residential areas. In this paper, we construct a multi-agent simulation model, which describes property damage (such as building-collapse, the spread of fire and blocking of streets) and people?s evacuation behavior after an earthquake occurring. Using this simulation model, we quantify the wide-area evacuation difficulty in densely-built wooden residential areas, and evaluate the past project to improve buildings and streets based on this indicator. Furthermore, we demonstrate the effects of adding new evacuation routes between two intersections of streets with narrow width and long distance. Through these case studies, the effectiveness of our simulation model on urban disaster mitigation planning is shown.

  Title Crowding of Various Facilities Relevant to Supporting People Who Have Difficulty Returning Home after a Large Earthquake Type Conference Article
  Year 2018 Publication ISCRAM 2018 Conference Proceedings – 15th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal Iscram 2018  
  Volume Issue Pages 45-59  
  Keywords Large earthquake, difficulty in returning home, temporary shelter, support station for people returning home on foot, crowding  
  Abstract When a large earthquake occurs, many people are presumed to have difficulty in returning home. However, no research has been achieved yet to discuss the congestion of supporting facilities for stranded people in terms of site, the number and spatial distribution. In this study, we construct a simulation model, which describes people's behavior such as returning home or going to other facilities after an earthquake occurs. Using the model, we estimate the congestion of facilities which varies according to day of the week or the time when the event occurs, and demonstrate the effective methods for reducing the congestion, which include offering information for people and cooperation of private institutions.

  Title Accessibility Evaluation of Specific Emergency Transportation Roads and Benefits of Seismic Retrofits on Buildings Adjoining Roads Type Conference Article
  Year 2020 Publication ISCRAM 2020 Conference Proceedings – 17th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal Iscram 2020  
  Volume Issue Pages 143-156  
  Keywords Accessibility of Emergency Vehicle, Specific Emergency Transportation Road, Quake-Resistant-Conversion of Building, Large Earthquake.  
  Abstract Securing the accessibility of emergency vehicles using specific emergency transportation road (SETR) is crucial for the rapid activities of emergency vehicles after a large earthquake. In this paper, we construct a simulation model that describes collapse of roadside buildings and following street blockages, and evaluate the accessibility of emergency vehicles. Performing the simulations, we demonstrate the effects of quake-resistant-conversion of roadside buildings as follows: (1) the accessibility of emergency vehicles using SETR is not good enough under the current situation, but (2) can be significantly improved by performing seismic retrofit of buildings according to seismic index of building structure.

  Title Simulation Analysis of Fire Hydrant Usability Levels after Large Earthquake Type Conference Article
  Year 2019 Publication Proceedings of the 16th International Conference on Information Systems for Crisis Response And Management Abbreviated Journal Iscram 2019  
  Volume Issue Pages  
  Keywords large earthquake; hydrant; water outage; fire-spread; firefighter  
  Abstract Since large earthquakes can disrupt water supply networks, it is essential to gain an understanding of the expected

usability of fire hydrants in post-quake firefighting activities. In this study, data about water supply networks was

collected and a water outage simulation model was constructed in order to predict the likelihood that individual

fire hydrants would become unusable in the wake of a large earthquake. The water outage simulation model was

integrated with a previously developed urban zone damage simulation and a fire department activity simulation

in order to carry out a simulation-based analysis of the 23 wards of Tokyo, after which a quantitative analysis of

the relation-ship between use of fire hydrants and the number of buildings lost to fire was performed. This analysis

revealed the benefits of hardening water lines against earthquakes, fire hydrant usage variations depending on

locality, and the benefits of using water pressure sensors to identify usable fire hydrants.

  Title Severity of Crowding at Evacuation Shelters after a Major Earthquake Type Conference Article
  Year 2022 Publication ISCRAM 2022 Conference Proceedings – 19th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal Iscram 2022  
  Volume Issue Pages 22-43  
  Keywords large earthquake; evacuation shelter; building damage; water-supply failure; simulation; evacuation behavior  
  Abstract A number of residents are presumed to evacuate to shelters after a large earthquake. However, the congestion of evacuation shelters has not been enough discussed. In this paper, we propose an evacuation behavior model, which includes sub-models on building damage, water-supply failure, power failure, fire damage, and elevator stall. Using the model estimated using the survey data of the past earthquakes, we discuss the congestion of evacuation shelters under the assumption of Tokyo Bay northern earthquake. Finally, we discuss improvement of water pipes for earthquake resistance to reduce the congestion degree of evacuation shelters, which varies according to regional vulnerability.

  Title The kashmir M7.6 shock of 8 october 2005 calibrates estimates of losses in future himalayan earthquakes Type Conference Article
  Year 2006 Publication Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2006  
  Volume Issue Pages 397-401  
  Keywords Information systems; Correction factors; Energy release; Kashmir earthquake; Large earthquakes; Loss estimates; Moment tensor solutions; Scenario earthquakes; Seismic risk; Earthquakes  
  Abstract In an article published in March 2005, we estimated the number of fatalities to be expected in future large earthquakes in the Himalaya (Wyss, 2005). For the scenario called Kashmir, we estimated that 67,000 to 137,000 fatalities should be expected. The M7.6 Kashmir earthquake of 8 October 2005 caused approximately 85,000 fatalities. Thus, one may argue that we forecast this disaster well. However, we assumed M8.1, a depth of 25 km and an epicenter located about 200 km to the SE from the October epicenter. Using the moment tensor solution for the October earthquake with a depth of 12 km for the energy release, we estimate the number of fatalities between 29,000 and 56,000. Thus, a factor of 2 must be applied to obtain the observed number, and the depth of the energy release in the scenario earthquakes should be placed at 12 km, which results in on over-All correction factor of 2.4. Therefore, we correct our estimates for numbers of fatalities in future Himalayan earthquake to range from 100,000 to 500,000, as specified for the locations given in Table 2.
