Response Plan

We applied a real-time tsunami inundation forecast system to a disaster response plan. We developed a standard operating procedure (SOP) for a tsunami disaster response based on a Plan, Do, Check, Action cycle to effectively use tsunami observation and prediction information provided by a real-time tsunami inundation forecast system during an initial response to a tsunami disaster. In the Plan stage, we ran a workshop on the tsunami disaster response to confirm the current tsunami disaster response plan and develop a timeline plan for a tsunami disaster. In the Do stage, we conducted a tabletop exercise (TTX) for a tsunami disaster using a real-time tsunami prediction system. In the Check stage, we ran a workshop on an after-action review of the TTX. In the Action stage, we applied the SOPs of the real-time tsunami prediction system to the tsunami disaster management plan and conducted a second TTX. As a result, we verified the information provided by a real-time tsunami prediction system to apply the system to a tsunami disaster management plan for real municipalities. It was confirmed that the SOP that we developed allows a real-time tsunami inundation forecast system to enable government staff to safely and effectively respond during a disaster.

Tsunami disasters can cause serious casualties and damage to social infrastructures. An early understanding of disaster states is required in order to advise evacuations and plan rescues and recoveries. We have developed a real-time tsunami inundation forecast system using a vector supercomputer SX-ACE. The system can complete a tsunami inundation and damage estimation for coastal city regions at the resolution of a 10 m grid size in under 20 minutes, and distribute tsunami inundation and infrastructure damage information to local governments in Japan. We also develop a new configuration for the computational domain, which is changed from rectangles to polygons and called a polygonal domain, in order to effectively simulate in the entire coast of Japan. Meanwhile, new supercomputers have been developed, and their peak performances have increased year by year. In 2016, a new Xeon Phi processor calledKnights Landingwas released for high-performance computing. In this paper, we present an overview of our real-time tsunami inundation forecast system and the polygonal domain, which can decrease the amount of computation in a simulation, and then discuss its performance on a vector supercomputer SX-ACE and a supercomputer system based on Intel Xeon Phi. We also clarify that the real-time tsunami inundation forecast system requires the efficient vector processing of a supercomputer with high-performance cores.

This paper gives attention to the phase of safety of work in wide-area support and considers differences in description in local disaster management plans drafted by supporting local governments and supported ones, assuming that standardization of such descriptions could bring more smooth and effective implementation of plans. This paper targets desirable directions toward arrangement for a highly effective wide-area cooperation system. A framework is introduced in examining on what wide-area support should be like, referring to previous studies on actual situation of the support at the time of the 1995 Southern Hyogo Prefecture Earthquake and of the 2004Mid Niigata Prefecture Earthquake. Then the disaster response activities in wide-area support are examines and local disaster management plans among different local governments are compared and differences in descriptions in plans. Necessary information for supporting sides and introduces the exchange of opinions with Kawasaki City that stood on the supporting side after the 2011 Great East Japan Earthquake is discussed. To make cooperation among the Japanese Government, prefectures, and municipalities more effective, the description of local disaster management plans should be standardized to some degree.

Evacuation Route

After the 2011 East Japan Earthquake, the Japanese Cabinet Office has promoted local governments and communities to develop a “Community Disaster Management Plan.” Local governments started to hold workshops to develop the said plan for residents in local communities. However, only a few residents (i.e., those who are interested in disaster prevention) participate in these workshops; thus, most residents do not have opportunities to survey disaster prevention. Considering this issue, we decided to develop a supporting application for individual disaster management plans by analyzing hazard risks and land features. In this research, we focused on evacuation planning for residents. Furthermore, we developed it as web-based application as any resident connected to the internet may be struggling with their evacuation. In our proposed application, users have to take seven steps: (1) learn features of tsunami attack and countermeasures during a tsunami disaster, (2) set start point for evacuation, (3) set first and second goal for evacuation based on lessons learned from the “Miracle of Kamaishi,” (4) search the shortest evacuation route from start point through the first goal to the second goal, (5) review change of elevation on the evacuation route, (6) review hazard risks and land feature on the evacuation route and to reroute if necessary, and (7) download their settled evacuation route to their own devices as a GPX file. After developing a prototype of the application, we published it as a web service. While the publishing was in process, we gathered logs on how users took actions based on our proposed application. Approximately 10 days after publishing the prototype, we analyzed the path of users’ action flow, and we detected issues that need to be resolved to improve esidents’ disaster management capacity during tsunami disasters. Generally, our application helped prepared users for tsunami disaster prevention.

It is important to advance preparation for a tsunami disaster, one of the great concerns in Japan. Forecasting tsunami inundation is one such solution, which contributes to perceiving the danger of the tsunami, as the inundation is directly linked with the damage. Therefore, we developed a new real-time tsunami forecast system, aimed at rapidly and accurately forecasting tsunami inundation on land, based on offshore tsunami data observed by the seafloor observation network along the Japan Trench, S-net. The developed system takes a database approach. A database called a tsunami scenario bank was constructed by assuming all the possible tsunami sources affecting the target region and simulating offshore pressure data, coastal tsunami heights, and tsunami inundation. The forecast system searches for suitable tsunami scenarios whose offshore pressure data explain the observed data, based on the multi-index method. The multi-index method can evaluate the resemblance of offshore pressure data by using three indices, which are sensitive to different aspects of the pressure change distribution. When tsunami scenarios meet the criteria of the multi-index method, the system provides forecast information generated from coastal tsunami heights and tsunami inundation of the selected scenarios. A prototype system was constructed for the Pacific coastal region of Chiba prefecture as a target region and has been updated through a test operation. We also investigated the comprehensible visualization and effective disaster response using tsunami forecast information. Through workshops and tabletop exercises with local government officers using the forecast system, timelines and local disaster management plans for tsunamis were tested and revised. This led to the establishment of a standard operating procedure for tsunami disaster response through the use of tsunami observation and forecast information.

Natural Disaster Management

Indonesia has the most complete types of disasters in the world such as floods, landslides, tidal waves, tornadoes, drought, forest and land fires, earthquakes, tsunamis, volcanic eruptions, liquefaction and many more. Natural disasters that occur in Indonesia often just happen and it is not predictable when it will happen. This causes problems in handling natural disasters. Natural disaster management is not a matter of BNPB or BPBD, one important element is the involvement of the Indonesian National Army (TNI). One of Indonesia's regions that are vulnerable to natural disasters is Lampung Province. This research will describe how the role of the TNI in the case study in Korem 043 / Gatam in helping to overcome natural disasters in Lampung Province. The research method used in this research is qualitative research with a literature study approach. The role of the TNI in disaster management in Lampung Province is inseparable from the duties and functions of the TNI that have been mandated in Law Number 34 of 2004. Korem 043 / Gatam has taken strategic steps both from the pre-disaster, disaster response, and post-disaster phases . TNI involvement in the process of disaster management does not stand alone, but cooperates and synergizes with local governments.

AbstractThe damage and loss of life caused by tsunamis can be reduced by timely warnings, which predict the arrival time and maximum height of tsunamis, to support evacuations and other mitigating actions. We have developed a real-time tsunami prediction system based on data from the Dense Oceanfloor Network system for Earthquakes and Tsunamis (DONET) that has been implemented in some local governments along the Pacific coast of Japan. The system generates estimates of tsunami arrival times and the height, inundation areas, and worst case using selected fault rupture models. The main objective of this paper is to show the possibility of applying the above system for a complicated topography area, and we report a successful application of the system in Sakaide, a city on the Shikoku coast of the Inland Sea, using a simulated great plate-boundary earthquake in the Nankai Trough. The simulated tsunami propagates to Sakaide by complicated routes between several islands. According to calculated tsunami waveforms of 1,506 cases, waveforms of tsunamis propagating to the Inland Sea have a relatively uniform frequency, regardless of the magnitude of the causative event, after running through the narrow straits in the Inland Sea. At the same time, waves are amplified as they pass between the islands of Shodoshima and Shikoku by an interaction with reflected waves. These effects are compatible with this prediction system, and we confirmed that our predicted tsunami is consistent with the final result from a model of a magnitude 9 Nankai Trough earthquake.

Introduction:One lesson learned from the 2015 Nepal earthquake was the need for a more coordinated effort between hospitals to improve disaster response. To improve the coordination, the concept of a hub and satellite system was introduced.Aim:Describe the implementation of a hub and satellite system in the disaster management plan to improve coordination and communication between hospitals and the health system during a disaster.Methods:A standard hospital disaster management plan was developed and validated with governmental and non-governmental agencies. Twenty-five hub hospitals within Nepal were identified. Smaller hospitals surrounding hub hospitals were identified as satellite hospitals. A plan was made to address communication and coordination between hub-satellite hospitals and ministry of health involving resource sharing, capacity analysis, and development of deployment teams in each hub. An output-based workshop was planned. Each hospital’s existing plans were evaluated before the workshop with a checklist containing essential components of disaster management. Each hospital was oriented and allowed to fill up a standardized template of a disaster management plan, after which their disaster management plan was reevaluated. The newly developed plan was then tested with a tabletop exercise function. The trainings were conducted from September 2017 to October 2018.Results:Disaster management plans were made in 110 hospitals, including nine hub hospitals and 101 satellite hospitals in three of seven provinces in Nepal. Evaluation of a pre-workshop score for the existing disaster plan was 18/32, and the score of the disaster plan post-workshop was 30/32 on average. The average score for hospitals for the tabletop exercise was 68.2% (53.8% to 84.6%).Discussion:A hub-satellite system-based disaster management plan has been developed and implemented in more than 100 hospitals in Nepal. Workshops for these hub and satellite hospitals improved their communication, coordination, and planning to improve disaster preparedness and future response.

In an endeavor to design better forecasting tools for real-time prediction, the present work highlights the strength of the multi-model multi-physics ensemble over its operational predecessor version. The exiting operational extended range prediction system (ERPv1) combines the coupled, and its bias-corrected sea-surface temperature forced atmospheric model running at two resolutions with perturbed initial condition ensemble. This system had accomplished important goals on the sub-seasonal scale skillful forecast; however, the skill of the system is limited only up to 2 weeks. The next version of this ERP system is seamless in resolution and based on a multi-physics multi-model ensemble (MPMME). Similar to the earlier version, this system includes coupled climate forecast system version 2 (CFSv2) and atmospheric global forecast system forced with real-time bias-corrected sea-surface temperature from CFSv2. In the newer version, model integrations are performed six times in a month for real-time prediction, selecting the combination of convective and microphysics parameterization schemes. Additionally, more than 15 years hindcast are also generated for these initial conditions. The preliminary results from this system demonstrate appreciable improvements over its predecessor in predicting the large-scale low variability signal and weekly mean rainfall up to 3 weeks lead. The subdivision-wise skill analysis shows that MPMME performs better, especially in the northwest and central parts of India.
