This method uses an indicator that considers the relationship of the duration from the time point at which the saturated zone is assumed to have formed to the average rainfall intensity during that period. The usefulness of this method has been verified, but its applicability to different slopes has not yet been investigated. Here, the authors collected long-term observations on a natural slope in Minamiashigara City, Kanagawa Prefecture, and examined the Modified I-D method using data on slope failures in the surrounding area. The authors also compared the results with plots of previous rainfall index (soil water index–accumulated rainfall in 60 min, effective rainfall amount with a half-life of 72 h–effective rainfall amount with a half-life of 1.5 h, and accumulated rainfall–accumulated rainfall in 60 min). The snake curves for rainfall events during slope failure and non-failure were clearly separated. The accuracy was high, confirming the applicability of the modified I-D method.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":" March","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138611352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latest earthquake and tsunami occurred on September 28, 2018 with a magnitude of Mw 7.4, which was centered on the ground and caused a large tsunami in Palu City. The earthquake and tsunami claimed 4,194 lives and damaged 55,102 buildings while missing, heavily, and lightly damaged. To reduce the impact of disasters, it is necessary to make efforts to increase awareness based on local wisdom so that it can be easily implemented in the community of Palu City. Local wisdom was explored by the people of Palu City and saw its effect on the level of alertness to disasters caused by the earthquake and tsunami. Local wisdom ombo is obtained from the people of Palu City, which contains a prohibition on building close to clean water sources. Data collection was carried out by conducting interviews with 121 affected communities regarding their knowledge, attitudes, and environmental conditions related to the level of vigilance. For environmental variables, local activity was a parameter included in the survey. The results of the analysis showed that the level of knowledge about the earthquake and tsunami as well as attitudes based on local wisdom increased the level of vigilance in disaster risk reduction efforts in Palu City. The results of the analysis showed that the implementation of attitudes based on local wisdom can affect the level of alertness with a value of 0.87, which means that the application of local wisdom can increase preparedness for earthquake and tsunami disaster. Indigenous latent variables (knowledge, attitudes, and environmental conditions) had a strong effect on exogenous latent variables (earthquake and tsunami preparedness) with an R2 value of 0.741.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":" 26","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138611394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observation period spans 24 years, from October 1998 to December 2022, and the number of earthquakes during the period is 12,064. Of these, 80.1% occurred between depths of 0.7 and 2.6 km; 94% registered between -1.6 and 0.9 on the Richter scale. The lower limit of the detectable magnitude (magnitude of completeness, Mc) for the transition of the volcano-observation system was examined and found to be -0.5 for Mc before 2005 and -1.4 for Mc after 2012. Focusing on zones where seismic activity was concentrated, we divided the active zones into four areas. The greatest concentration of seismic activity, 76.4% of the total number of earthquakes, was between Chausu-dake and Asahi-dake. The depth of the earthquakes in this active area was shallower than 2 km, and most were micro-earthquakes (1 ≤ M < 3) or smaller. Earthquakes have been occurring regularly for 24 years. This active area includes the Chausu-dake lava dome formed by activities in 1408–1410 and two craters where phreatic eruptions have occurred since the Meiji era (1868–1912). Therefore, in considering volcano disaster-prevention measures, the relationship between this seismic area and volcanic activity should continue to be closely monitored.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135373321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a method for estimating the risk of a sudden and significant decline in sales to tackle the aforementioned issue. The method is based on the distributional characteristics calculated from historical data of companies mainly in the transportation industry, which are vulnerable to disasters, using the damage caused by COVID-19 as a lesson. Furthermore, we conduct an empirical analysis using the proposed stochastic model for the case of the All Nippon Airways Co., Ltd. (ANA), a major Japanese airline company. The results are as follows: (1) the sales change rates are normally distributed before COVID-19, but inclusion of post-COVID-19 data produced asymmetric distribution of sales change rates; (2) the proposed statistic is log-normally distributed (including post-COVID-19 data) for a time interval of two or three years; (3) the probability of actual sales decline was estimated to be between 0.1% and 1.6% in fiscal year (FY) 2020 and FY2021 post-COVID-19; (4) the estimated risk of future sales decline is well-grounded in light of past actual values.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135373319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The behavior and failure mechanisms of conventional MSE walls have been carefully examined. In cases where space is limited, such as in mountainous regions, in coastal regions, and for road expansion, the conventional MSE wall can be modified by adjusting the length of reinforcement to conform the construction area. For narrow geosynthetic reinforced soil (GRS) wall, the modification and arrangement of reinforcement components, including reinforcement tensile strength, vertical spacing, and aspect ratio, play key roles in the behavior of reinforced earth walls and can also lead to differences in the distribution of lateral earth pressure compared with conventional MSE walls. In this study, a series of geotechnical centrifuge tests are conducted to clarify the failure behaviors, distribution of lateral earth pressure, and deformation progresses of narrow GRS walls. Among the investigated variants, it is verified that improved reinforcement strength leads to a significant decrease in horizontal wall displacement. The relationship among lateral earth pressure, zero-earth-pressure zone, and horizontal displacement can be applied to predict the deformation of a narrow GRS wall.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135373325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first paper, authored by Dhakal and Kunugi, presents the orientation changes that earthquake movements have caused in the accelerometers of a seafloor observation network for earthquakes and tsunamis along the Japan Trench (S-net). This study is expected to contribute to more accurate analyses of S-net data. The second and third papers are reports of research done on volcanoes. The paper by Tanada and Ueda presents the seismic activity of the Nasudake volcano through the use of NIED hypocenter data gathered from 1998 to 2022. Tanada and Ueda state that earthquakes have regularly occurred near the Chausudake lava dome and two craters and that, from the volcano disaster-prevention point of view, it is important to monitor the relationship between this seismic area and volcanic activity. The third paper, by Miyagi et al., reports on an experiment aimed at grasping the movement of climbers and sharing the level of disaster threat with climber-related organizations in real time. Their online visualization system for the movement of climbers helps to provide solutions to problems related to volcanic disaster prevention not only during disaster events but also in the periods between. The last paper is a tutorial by Hanashima and Usuda on “SIP4D-ZIP,” which is a standard for synthesizing and sharing common information from multiple organizations. This tutorial explains how to realize a versatile and automatic mutual data sharing and usage system for various kinds of necessary disaster information. In conjunction with the fourth 7-year mid/long term plan period 2016-2022, NIED has published seven special issues since 2017, including this 2023 issue. We believe that the articles in these seven issues can contribute to the advancement of science and technology for disaster risk reduction and resilience.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135373316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In past large-scale disaster responses, it has often been necessary to share information that could not be predicted in advance with several organizations. Even if such information could be converted into electronic data, the valuable information was sometimes not fully utilized due to the lack of a common format for describing the meaning of the data or lack of the data format that can be read by different systems. To solve such problems, we developed SIP4D-ZIP as a common data framework that enables data to be exchanged between systems without prior arrangement. We demonstrate how SIP4D-ZIP can solve the problems found in actual disaster response, which are the background of the design concept of SIP4D. Furthermore, we explain in detail how SIP4D-ZIP works and show that it can automate the processes required to share information between systems. We believe that designing both the information source system and the utilization system based on SIP4D-ZIP will enable highly versatile and automatic mutual sharing of disaster information and promote digital transformation in disaster response.","PeriodicalId":46831,"journal":{"name":"Journal of Disaster Research","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135373327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
