This paper develops a theoretical framework through literature review coupling the concepts of “disaster hazards”, “vulnerability” and “informal settlements”. Abstract The aim and objective of this paper are to highlight the landslide vulnerability with the help of analytical hierarchy process and geographic information system (GIS) tools. Of 64 districts in the country, eight were exposed by landslide episodes, five were recognized as profoundly affected. Useful applications of the proposed method lie in a better territorial management and in the land use planning. Every year since 2000, when the population of the eight counties of southern California was nearly 19.7 million people, an estimated 276,000 more people become at risk from primary and secondary natural hazards. In this approach a grid based Geographic information system (GIS) was used to construct a landslide hazard map for east part of Norway Romsdal region. this study include rock type, geomorphology, slope, aspect, drainage density, soil type and land use and land cover. All of these parameters are compiled and analyzed with “Landslide Distribution Map” (LDM) to generate a “Landslide Vulnerability Degree map (LVD)”. a rainstorm, an earthquake, a rapid snowmelt event), or by multiple events in a short or long period. 0.1° x 0.1° or 0.25° x 0.25° . Join ResearchGate to find the people and research you need to help your work. A dataset of landslides from Sichuan Province in China, containing 1551 historical individual landslides, is a result of two teams’ effort in the past few years to map the susceptibility to landslides. Informal settlements, where mostly the urban poor reside, tend to be located in hotspots of natural hazards such as floods, fire, earthquakes and tsunamis. In recent years, these techniques have been successfully integrated and shown to be complementary and competitive with more standard remote sensing techniques, such as satellite or terrestrial Synthetic Aperture Radar interferometry. This book is one out of 8 IAEG XII Congress volumes, and deals with Landslide processes, including: field data and monitoring techniques, prediction and forecasting of landslide occurrence, regional landslide inventories and dating studies, ... A formal risk assessment procedure, which allows one to rigorously compare different landslide mitigation approaches, is developed. By using Tianjin Port Explosion in 2015 as the case study, Chapter 3 evaluates observed and projected changes in the frequency, intensity, spatial extent, and duration of extreme weather and climate events. Earth flow, mass movement, mudflow, rotational slip, and avalanches are all examples of landslides. Recent advances in risk analysis and risk assessment are beginning to provide systematic and rigorous processes to enhance slope management. the inclusion criteria which inherently results in many hazard events not being registered. It has been Consequently, levels of uncertainty linked to landslide risk assessment remain a challenge to be addressed. This provides understanding about the stock of asset which may be vulnerable to different . This study aims at quantifying direct economic losses from debris flows at a medium scale in the study area in Italian Central Alps. Finally, the total average of index value for the three types of physical, human and environment vulnerabilities is classified into five classes of vulnerabilities, namely class 1 (< 0.20) (very low vulnerability), class 2 (0.21-0.40) (low vulnerability), class 3 (0.41-0.60) (medium vulnerability), class 4 (0.61-0.80) (high vulnerability) and class 5 (> 0.81) (very high vulnerability). Found inside – Page 98A column was added to the hazard matrix to consider the area not affected by existing landslides, in which future ... Five vulnerability classes were associated to the following score ranges: null (V to 0 0.25–0.45, ) to (V ues, ... New approach in vulnerability concept in landslide risk management (LRM) in Malaysia is also introduced. In the Philippines, for example, landslide occurrences claimed hundreds of lives and caused . 2014a;Lu et al. Found insideIn this book, multiple experts present their work on various engineering characteristics of rainfall. The topics presented will update the readers on the recent developments and their applications across different regions of the world. Because of the potential for crisis and the seasonal landslide activity, direct or indirect, immediate and delayed impact have been identified. The frontal walls and side walls are vulnerable to any type of flow. The quantification of tangible and intangible potential losses is a critical step because it provides essential data upon which judgments can be made and policy can be formulated. The vulnerability values obtained with the local (Model 1) and regional (Model 2) models are further multiplied with the building value to calculate the minimum and maximum loss for each building in the study area. The innovative concept of economic landslide susceptibility (that is de facto an ex ante landslide cost assessment) may be interpreted as the potential loss that an area might suffer in terms of its propensity for landslides. The methodology is applied in the Fella River valley (northeastern Italian Alps), a region prone to multiple mountain hazards. Así mismo, la metodología empleada puede ser extrapolada Neue Perspektiven auf soziale und klimatische Vulnerabilität, Landslide Susceptibility Mapping Based on the Deep Belief Network: A Case Study in Sichuan Province, China, Landslide hazard assessment, vulnerability estimation and risk evaluation: An example from the collazzone area (CENTRAL UMBRIA, ITALY), Landslide Consequences and Post Crisis Management Along the Coastal Slopes of Normandy, France, Landslide impacts in Germany: A historical and socioeconomic perspective, Regional Cooperation Newsletter-South Asia - Froth, Fire in Bengaluru Lakes and the Need for Ecosocial Transition, Methods for the Characterization of the Vulnerability of Elements at Risk, Digital Image Correlation (DIC) Analysis of the 3 December 2013 Montescaglioso Landslide (Basilicata, Southern Italy): Results from a Multi-Dataset Investigation, Fragility and Bearing Capacity of Gray Shales in North-Eastern Jamaica After Landslips: Origins, and Implications for Open-Cut Mines, Potential Landslide Vulnerability Zonation Using Integrated Analytic Hierarchy Process and GIS Technique of Upper Rangit Catchment Area, West Sikkim, India, Evaluation of the susceptibility to landslides through diffuse logic and analytical hierarchy process (AHP) between Macas and Riobamba in Central Ecuador, Buildings and Business, Love and Forgiveness, Landslide warning system in the San Francisco Bay Region, A system of monitoring and warning in a complex landslide in Northeastern Italy, Study on the Reserve of China’s Professional Relief Workers under Frequent Natural Disasters. For example, Fig. In these maps, the landslide hazard probability values comprise five categories from very low (0.0-0.1) to very high (0.4-0.5). throughput and physical damages. Regions with high vulnerability 1. in the export mode. could cause a total loss of 0.91 USD billion in the studied terminal, which is Landslides are one of the most substantial damaging and recurrent disasters in the hilly areas of Bangladesh. Found insideThe first part of the book contains state-of-the-art and invited lectures, prepared by teams of authors selected for their experience in specific topics assigned to them by the JTC Further, port vulnerability assessment against repetitive catastrophes is conducted by CO Survey, 1988 The framework was formulated semi-quantitatively through the development of a database for the risk elements (human & properties) based on secondary data, review of literature and field observations. Found inside – Page 582of Landslides in the Natural Environment Many papers have been written on the socioeconomic impacts of landslides on the ... Measures to reduce social vulnerability 0 Investments for landslide risk mitigation and reduction 0 Insurance. mitigation policies and cooperation. Vulnerability is defined as the degree of losses of a given element at risk of being exposed to the occurrence of a landslides of a given magnitude or intensity, and often expressed on a scale of . Such information is often unavailable to, or not easily interpreted by, those who might need it most (e.g. In landslide-prone areas, the vulnerability of housing structures is assessed so that adaptation methods can be introduced to reduce risk. Landslide area, as well as temporary landslide-dammed lakes, were semi-automatically identified using object-based image analysis (OBIA), based on 20 Landsat images from 1984 to 2018. The study deals with landslide threats in a low-relief region which exemplifies an area rarely perceived as prone to such geohazards. van Westen . For a given case study site, inputs to the model are population data, building characteristics, volcano scenarios as a series of hazard intensities, and scenarios such as the time of eruption or the percentage of the population which has been evacuated. Found insideThis book contains concrete experiences and examples from Africa, Asia, the Americas and Europe to illustrate the theoretical analyses.The authors provide answers to some of the key questions on how to measure vulnerability and they draw ... Finally, that inter- and trans-disciplinary approaches to landslide risk prevention need to be integrated into municipal-level planning for a better understanding of—and prevention of—socio-natural hazards. The current paper aims at proposing and integrating certain indicators into the methodology used in the evaluation of exposure to both slope and riverbed geomorphologic processes, and hydrologic processes, as: (i) distance from landslides; (ii) distance from riverbanks; (iii) water level growth in case of floods; (iv) service capacity of roads. The examples include: (i) the determination of societal and individual levels of landslide risk in Italy, and a comparison with risk levels posed by other natural and man-made hazards, and by the principal medical causes of deaths in Italy, (ii) a preliminary attempt to establish the geographical distribution of landslide risk to the population . In addition, we introduce and test two new metrics: the maximum angle to the skyline and the hazard area, defined as the upslope area with slope >40∘ from which landslide debris can reach a location without passing over a slope of 10∘) channels with many steep (>40∘) areas that are upslope”. Found insideWe hope that chapters of this book will provide useful information within crisis management issue for a wide audience. The fatal database of Turkey (FATALDOT) shows that, in total, 1343 people were killed in 389 fatal landslide events. 2014 New York State Hazard Mitigation Plan Landslide 3.14-1 Final Release Date January 4, 2014 Section 3.14 LAN SL 2014 SHMP Update Reformatted document into new outline Updated data related to occurrence, vulnerability and loss This situation has increased the landslide risk in areas behind the Sierra Madre Oriental mountains, causing large-scale damage including damage to facilities and loss of life. Some of these assumptions have conceptual weakness, and the methods have revealed limitations. 2008;Uzielli et al. 1973. The objective of this article is to apply the proposed in-depth calibration and validation analysis, referred to as the Digital Image Correlation technique, to measure landslide displacement. توزیع زمین لغزش‌های مرگبار با دو روند رشته کوه‌های البرز و زاگرس همخوانی دارد. To understand impacts triggered by weather and climate events, the exposure and vulnerability of humans and ecological systems need to be examined. The selection of the best LVAs depends on the exposed elements, landslide types and the scale of analysis. The relationship between Public Works Department to mitigate landslides in Malaysia. The probability of landslide size was obtained by analyzing the frequency-area statistics of landslides. Consequently, the port and industrial clusters vulnerability Landslide hazard, vulnerability, and risk-zoning maps are considered in the decision-making process that involves land use/land cover (LULC) planning in disaster-prone areas. Household per capita income and education level of the household head had a significant influence on vulnerability to cut slope failures. In this work residents’ social vulnerability and buildings’ physical vulnerability of the Loures municipality (Portugal) were combined to locate the areas where the vulnerability is the highest, and to analyse the landslide risk. Values attributed to elements at risk were defined considering reconstruction costs, following the guidelines of the Portuguese Insurance Institute. ideal solution (TOPSIS). This person is not on ResearchGate, or hasn't claimed this research yet. A Hot Spot Analysis tool (Getis-Ord- Gi* algorithm) was used to identify the spatial concentration of high and low landslide affected areas in Bangladesh. The results reveal the choice to live in areas of cut slope failure risk was dependent on a number of different priorities for communities and that 82% of houses had a moderate vulnerability. 1).These can be subdivided into four groups: landslide inventory data, environmental factors, triggering factors, and elements at risk (Van Westen et al., 2005).Of these, the landslide inventory is by far the most important, as it . Landslides are one of the most damaging geohazard phenomena in terms of historical death tolls and socioeconomic losses. Afterwards, a qualitative risk map derived using a risk matrix officially provided by the set of laws issued by the regional government, was prepared. landslide hazard map - hazard maps show the areal extent of threatening processes: where landslide processes have occurred in the past, where they occur now, and the likelihood in various areas that a landslide will occur in the future. The proposed study aims to create a tool that can be adjusted to user-specific needs to support decision-making, to reduce risk, and for disaster management at the local levels. In the example taken in Section 6.2, there are eight identified tsunami sources in the North Atlantic Ocean, six of these contribute significantly to the hazard curve in the danger zone on Figure 7. Quantitative analysis of consequences (in terms of expected monetary losses) induced by slow-moving landslide mechanisms to buildings or infrastructure networks is a key step in the landslide risk management framework. While a variety of indices exist at the individual, household, community, sub-national, national and global levels, ( 19 ) there is little agreement in the literature on how best to capture this amorphous concept. In Portugal, landslides are quite frequent and have been responsible for damage and disruption on roads and buildings. the slopes in Malaysia. 2011;Totschnig et al. However, there is a lack of an official database to analyze the trends of the landslide disaster in Bangladesh. It is very frequent in geodynamical active domains in the Himalayan and Arakan- Yoma belt of the Northeastern parts of the country as well as in the relatively stable domains of the Meghalaya Plateau, Western Ghats, and Nilgiri Hills. Quantitative risk analysis for landslides -- Examples from B ldudalur, NW-Iceland By Thomas Glade and Rainer Bell Multi-hazard analysis in natural risk assessments It is . This paper provides a brief review of approaches to multi-hazard landslide risk assessment and discusses several key issues in such assessment. Methods for quantifying the risk are discussed, and qualitative definitions are suggested for use when these are desirable. The LDM was produced based on field studies and satellite image interpretations in order to locate the landslide locations in the studied area. landslide dam - an earthen dam created when a landslide completely blocks a stream or river. The probabilities of the nodes (factors) and the arcs (inter-relationships) of the network are quantified according to statistical data, judgment based on experiences, and existing physical or empirical models. The paper concludes by identifying five theoretical propositions that can assist in disaster preparedness. These datasets were combined to produce a GIS-predicted isoseismal map of the area around Uttarkashi, Garhwal Himalayas, India. Rapid slaking of the illitic shales could cause high turbidity levels in contiguous aquatic environments. 3 Presentation on "Landslide Risk Assessment" by Xuanmei Fan, Runqiu Huang, and Cees Van Western. Devastating landslides were frequently triggered by earthquakes and caused severe damage and human losses. For example, assessments of regional landslide 'hazard', if they exist at all, are more likely to rank components of the terrain in terms of their potential for landslide occurrence (susceptibility) or simply indicate the presence or absence of existing landslides (Crozier . using the developed port operation simulation-based model. 213. - Vulnerability: the level of population, property, economic activity, including public services, etc., at risk in a given area resulting from the occurrence of a landslide of a given type. Upon impact by a debris flow, both the local column failure and the global pushover collapse of building can occur, as debris flows with high solid contents are an intermediate flow sharing characteristics of both floods and earth flows. Results on the application of the method show vulnerability estimates for susceptible categories on structures and people for prescribed study areas. It also provided many valuable lessons for mitigating future earthquake loss. The natural disaster risk level does not only depend on the natural hazard intensity but also count on the vulnerability and exposure of the hazard-bearing bodies. Adding the subscores will produce a total score for each hazard. The study was partially funded by a grant from the Union of British Columbia Municipalities. IntroductionSlope Stability ConsiderationsLandslide TypesImpactFrequency—Magnitude IssuesVulnerability with Respect to Landslide TypesConclusion. This chapter will conclude with a comparison of the resilience characteristics of an indigenous community that has lived in the region for several generations, and has developed characteristics worth studying in connection with resilience in the newer communities. Landslide destroyed an entire neighborhood and took 43 lives. system. Ground ruptures caused by unusually large thrust and left-lateral displacement of the east-dipping fault resulted in almost total destruction of structures on the hanging-wall block along the 100-km-long fault zone. Each considered parameter in the vulnerability assessment is allocated with a certain index value ranges from 0 (0 % damage/victims/period), 0.25 (1 - 25% damage/victims/period), 0.50 (26 - 50% damage/victims/period), 0.75 (51 - 75% damage/victims/period), and 1.00 (75 - 100% damage/victims/period).
