| 1 | Seismogenic fault and topography control on the spatial patterns of landslides triggered by the 2017 Jiuzhaigou earthquake显示文摘Jiuzhaigou National Park, located in northwest plateau of Sichuan Province, is a UNESCO World Heritage Site, and one of the most popular scenic areas in China. On August 8, 2017, a Mw 6.5 earthquake occurred 5 km to the west of a major scenic area, causing 25 deaths and injuring 525, and the Park was seriously affected. The objective of this study was to explore the controls of seismogenic fault and topographic factors on the spatial patterns of these landslides. Immediately after the main shock, field survey, remote-sensing investigations, and statistical and spatial analysis were undertaken. At least 2212 earthquake-triggered landslides were identified, covering a total area of 11.8 km^2. Thesewere mainly shallow landslides and rock falls. Results demonstrated that landslides exhibited a close spatial correlation with seismogenic faults. More than 85% of the landslides occurred at 2200 to 3700 m elevations. The largest quantity of landslides was recorded in places with local topographic reliefs ranging from 200 to 500 m. Slopes in the range of ~20°-50° are the most susceptible to failure. Landslides occurred mostly on slopes facing east-northeast(ENE), east(E), east-southeast(ESE), and southeast(SE), which were nearly vertical to the orientation of the seismogenic fault slip. The back-slope direction and thin ridge amplification effects were documented. These results provide insights on the control of the spatial pattern of earthquake-triggered landslides modified by the synergetic effect of seismogenic faults and topography. | WU Chun-hao CUI Peng LI Yu-sheng Irasema Alcántara AYALA HUANG Chao YI Shu-jian | 2018 | Journal of Mountain Science2018，15，4： | 11 |
| 2 | A Likert Scale-Based Model for Benchmarking Operational Capacity,Organizational Resilience,and Disaster Risk Reduction显示文摘Likert scales are a common methodological tool for data collection used in quantitative or mixed-method approaches in multiple domains.They are often employed in surveys or questionnaires,for benchmarking answers in the fields of disaster risk reduction,business continuity management,and organizational resilience.However,both scholars and practitioners may lack a simple scale of reference to assure consistency across disciplinary fields.This article introduces a simple-to-use rating tool that can be used for benchmarking responses in questionnaires,for example,for assessing disaster risk reduction,gaps in operational capacity,and organizational resilience.We aim,in particular,to support applications in contexts in which the target groups,due to cultural,social,or political reasons,may be unsuitable for in-depth analyses that use,for example,scales from 1 to 7 or from 1 to 10.This methodology is derived from the needs emerged in our recent fieldwork on interdisciplinary projects and from dialogue with the stakeholders involved.The output is a replicable scale from 0 to 3 presented in a table that includes category labels with qualitative attributes and descriptive equivalents to be used in the formulation of model answers.These include examples of levels of resilience,capacity,and gaps.They are connected to other tools that could be used for in-depth analysis.The advantage of our Likert scale-based response model is that it can be applied in a wide variety of disciplines,from social science to engineering. | Gianluca Pescaroli Omar Velazquez Irasema Alcántara-Ayala Carmine Galasso Patty Kostkova David Alexander | 2020 | International Journal of Disaster Risk Science2020，11，3： | 8 |
| 3 | Landslide risk perception and communication for disaster risk management in mountain areas of developing countries:a Mexican foretaste显示文摘The increasing impact of disasters at local,national,regional and global scales in recent decades has provided enough evidence to urgently direct attention towards the necessity of disaster risk reduction and management,and this requires knowledge.Knowledge without communication is barren,and to communicate the risk of disaster it is necessary to understand the perception of the people at risk.In particular,this paper deals with the necessity to delineate strategies of risk communication in pursuance of risk knowledge as a core of disaster risk reduction and management,especially in mountain areas of developing countries.To portray this issue,an analysis of landslide risk perception in terms of experience,landslide risk awareness,exposure,preparedness,and risk communication and trust was undertaken in the municipality of Teziutlán,Puebla,Mexico,an area that has been affected for several decades by episodes of mass movement.Analysis of the responses to a risk perception questionnaire has offered valuable insights in terms of the information and knowledge most required by the people living in the area of interest,in order to devise a realistic and functional strategy to communicate the risk of a landslide disaster.This includes better understanding of controlling factorsand drivers of this risk,and the establishment of potential trusted sources of risk communication.Beyond considering practical matters of risk assessment and management,risk perception and communication can increase the resilience of vulnerable people,and can enhance capacity building for present and future generations. | Irasema ALCáNTARA-AYALA Ana Rosa MORENO | 2016 | Journal of Mountain Science2016，13，12： | 6 |
| 4 | The 4th World Landslide Forum: Landslide Research and Risk Reduction for Advancing the Culture of Living with Natural Hazards显示文摘The World Landslide Forum is a triennial mainstream conference that gathers together the scientific and technological community, policymakers, industry actors, public officials, and other stakeholders, who deal with the understanding and management of landslide disaster risk. The establishment of the ISDR-ICL Sendai Partnerships 2015–2025 for Global Promotion of Understanding and Reducing Landslide Disaster Risk in Sendai during the 2015 World Conference on Disaster Risk Reduction(WCDRR) enabled the landslide science and technology community support the implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030 in order to prevent new and reduce existing disaster risk.The 4th World Landslide Forum(WLF4) was held in Ljubljana, Slovenia, from 29 May to 2 June 2017 and discussed the progress of landslide research and risk reduction for advancing the culture of living with natural hazards. A high-level panel composed of United Nations officials, international stakeholders, and national organizations sought to identify the best mechanisms to be developed by the community of the International Consortium on Landslides(ICL). The objective was to advance the implementation of the ISDR-ICL Sendai Partnerships,to achieve a better commitment among partners, and to provide substantive services to developing countries. During the WLF4, the 2017 Ljubljana Declaration on Landslide Risk Reduction was adopted and the concept framework of the Kyoto 2020 Commitment was endorsed. | Irasema Alcntara-Ayala Kyoji Sassa Matjaz Miko Quinli Han Jakob Rhyner Kaoru Takara Satoru Nishikawa Badaoui Rouhban Slvano Briceo | 2017 | International Journal of Disaster Risk Science2017，8，4： | 3 |
| 5 | The use of UAVs for landslide disaster risk research and disaster risk management: a literature review显示文摘On a global scale,from 2005 to 2019,there were 275 high-magnitude,low-frequency disasters that involved 14,172 fatalities and four million affected people.Similar patterns have taken place during longer periods of time in recent decades.This paper aims to analyse the contribution of the international landslide research community to disaster risk reduction and disaster risk management in reference to the use of Unmanned Aerial Vehicles(UAVs)in a literature review.The first section notes the relevance of disaster risk research contributions for the implementation of initiatives and strategies concerning disaster risk management.The second section highlights background information and current applications of drones in the field of hazards and risk.The methodology,which included a systematic peer review of journals in the ISI Web of Science and SCOPUS,was presented in the third section,where the results include analyses of the considered data.This study concludes that most current scholarly efforts remain rooted in hazards and post-disaster evaluation and response.Future landslide disaster risk research should be transdisciplinary in order to strengthen participation of the various relevant stakeholders in contributing to integrated disaster risk management at local,subnational,national,regional and global levels. | Ricardo J.GARNICA-PEÑA Irasema ALCÁNTARA-AYALA | 2021 | Journal of Mountain Science2021，18，2： | 3 |
| 6 | Early Warning Systems: Lost in Translation or Late by Definition? A FORIN Approach显示文摘Early warning systems(EWSs) are widely considered to be one of the most important mechanisms to prevent disasters around the globe. But as disasters continue to affect countries where EWSs have already been implemented, the striking disaster consequences have led us to reflect on the focus, architecture, and function of the warning systems. Since the 2004 Indian Ocean tsunami there has been a rapid rise in the promotion and use of EWSs to minimize disaster losses and damage. However,few researchers have addressed the question of their acceptability as an adaptive measure to the existing exposure conditions. EWSs are far more linked to emergency response and humanitarian crises and accepted technological interventions as solutions than they are to explicitly advance integrated analysis, disaster risk reduction, and policy making. A major flaw of EWSs is that the term‘‘early’’ has been essentially used in reference to the speed of hazard onset, founded on a physicalist perspective that has encouraged a considerable dependence on technology.In this article we address the need for a clear understanding of the root causes and risk drivers of disaster risk creation,as advanced in the FORIN(forensic investigation of disasters) approach, as a prerequisite for the development of more articulated EWSs that could contribute to disaster risk reduction through policy making and practice, based on integrated and transdisciplinary management, in the interest of sustainable development, and human welfare and well-being. | Irasema Alcántara-Ayala Anthony Oliver-Smith | 2019 | International Journal of Disaster Risk Science2019，10，3： | 2 |
| 7 | Hazard and population vulnerability analysis: a step towards landslide risk assessment显示文摘In this paper, an attempt to analyse landslide hazard and vulnerability in the municipality of Pahuatlán, Puebla, Mexico, is presented. In order to estimate landslide hazard, the susceptibility,magnitude(area-velocity ratio) and landslide frequency of the area of interest were produced based on information derived from a geomorphological landslide inventory; the latter was generated by using very high resolution satellite stereo pairs along with information derived from other sources(Google Earth,aerial photographs and historical information).Estimations of landslide susceptibility were determined by combining four statistical techniques:(i) logistic regression,(ii) quadratic discriminant analysis,(iii) linear discriminant analysis, and(iv)neuronal networks. A Digital Elevation Model(DEM)of 10 m spatial resolution was used to extract the slope angle, aspect, curvature, elevation and relief.These factors, in addition to land cover, lithology anddistance to faults, were used as explanatory variables for the susceptibility models. Additionally, a Poisson model was used to estimate landslide temporal frequency, at the same time as landslide magnitude was obtained by using the relationship between landslide area and the velocity of movements. Then,due to the complexity of evaluating it, vulnerability of population was analysed by applying the Spatial Approach to Vulnerability Assessment(SAVE) model which considered levels of exposure, sensitivity and lack of resilience. Results were expressed on maps on which different spatial patterns of levels of landslide hazard and vulnerability were found for the inhabited areas. It is noteworthy that the lack of optimal methodologies to estimate and quantify vulnerability is more notorious than that of hazard assessments.Consequently, levels of uncertainty linked to landslide risk assessment remain a challenge to be addressed. | Franny G.MURILLO-GARCíA Mauro ROSSI Francesca ARDIZZONE Federica FIORUCCI Irasema ALCáNTARA-AYALA | 2017 | Journal of Mountain Science2017，14，7： | 2 |

| 10 | Disaster risk reduction in mountain areas: an initial overview on seeking pathways to global sustainability显示文摘As disasters cripple the world’s prospects for sustainable development, protecting the most vulnerable groups exposed to hazards is one of the main challenges facing humanity. Owing to the systemic nature of risk and the interactions and interdependencies between upland and lowland systems, healthy and productive mountain households and livelihoods are essential to global sustainability. This paper argues that, building on existing international frameworks, and integrated knowledge and praxis, the development of a global policy agenda should be established to build sustainable peace, sustainable security, and development. | ALCáNTARA-AYALA Irasema PASUTO Alessandro CUI Peng | 2022 | Journal of Mountain Science2022，19，6： | 1 |

| 15 | Multi-Sectoral Reflections and Efforts in Strengthening Partnerships to Reduce Disaster Risk in Mexico:The First MuSe-IDRiM Conference显示文摘Notwithstanding the high societal impact of disasters in Mexico,there is a lack of integrated efforts to establish a sound policy for reducing disaster risk to counterbalance the existing concentrated endeavors in disaster management.In the face of such segmentation,the science and technology community has advocated for a change of perspective,from civil protection to integrated disaster risk managemcnt.The first Multi-Sectoral Conference towards Integrated Disaster Risk Management in Mexico:Building a National Public Policy(MuSe-IDRiM Conference)was held in Mexico City at National Autonomous University of Mexico,21-24 October 2019.In support of the implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030,the conference aimed at enhancing the dialogue between the scienee and technology community,citizens,civil society organizations,private and public sectors,and the federtil,state,and municipal governments to foster the process of transforming the current National Civil Protection System into a national public policy oriented towards integrated disaster risk management(DRM).Barriers and challenges to the implementation of integrated DRM were identified.Implementation of integrated DRM challenges current socioeconomic structures and encourages all releva nt stakeholders to think,decide,and act from a different perspective and within and across spatial,temporal,jurisdictional,and institutional scales.Understanding disaster risk from an integrated approach,learning skills that authorities have not learned or used,and hence,strengthening disaster risk governance are prerequisites to effectively manage disaster risk. | Irasema Alcantara-Ayala Daniel Rodriguez-Velazquez Ricardo J Garnica-Pena Alejandra Maldonado-Martinez | 2020 | International Journal of Disaster Risk Science2020，11，5： | 0 |

| 17 | Landslide susceptibility: a statistically-based assessment on a depositional pyroclastic ramp显示文摘This study aimed to produce a high-quality landslide susceptibility map for Teziutlán municipality, a landslide-prone region in Mexico, which is characterised by a depositional pyroclastic ramp. The heterogeneous quality of available topographic information(i.e. higher resolution digital elevation model only for a sub-region) encouraged to confront modelling results based on two different study area delineations and two raster resolutions. Input data was based on the larger modelling region L15(163 km2) and smaller S(70 km2; located inside L15) with an associated raster cell size of 15 m(region L15 and S15) and 5 m(region S5). The resulting three data sets(L15, S15 and S5) were included into three differently flexible modelling techniques(Generalized Linear Model-GLM, General Additive Model-GAM, Support Vector Machine-SVM) to produce nine landslide susceptibility models. Preceding variable selection was performed heuristically and supported by an exploratory data analysis. The final models were based on the explanatory variables slope angle, slope aspect, lithology, relative slope position, elevation, convergence index, distance to streams, distance to springs and topographic wetness index. The ability of the models to classify independent test data was elaborated using a k-fold cross validation procedure and the AUROC(Area Under the Receiver Operating Characteristic) metric. In general, all produced landslide susceptibility maps depicted the hillslopes of the ravines, which cut the pyroclastic ramp, as prone to landsliding. The modelling results showed that predictive performances(i.e. AUROC values) slightly increased with an increasing flexibility of the applied modelling technique. Thus, SVM performed best, while the GAM outperformed the GLM. This tendency was most distinctive when modelling with the largest landslide sample size(i.e. data set L15; n = 662 landslides). Non-linear classifiers(GAMs, SVMs) performed slightly better when trained on the basis of lower raster resolution(data set S15) compared to the 5 m counterparts(data set S5). Highest predictive performance was obtained for the model based on data set L15 and the SVM classifier(median AUROC: 0.82). However, SVMs also indicated the highest degree of model overfitting. This study indicates that the decision to delineate a study area, the selection of a raster resolution as well as the chosen classification technique can affect varying aspects of subsequent modelling results. The results do not support the assumption that a higher raster resolution(i.e. a more detailed digital representation of the terrain) inevitably leads to better performing or geomorphically more plausible landslide susceptibility maps. | Franny G.MURILLO-GARCíA Stefan STEGER Irasema ALCáNTARA-AYALA | 2019 | Journal of Mountain Science2019，16，3： | 0 |
