Case ReportOpen accessEvery word in the titleWeb-Based Emergency Management Information System for Landslides OccurrencesJordan H. Souza, Carlos A.P. Soares, Gislaine Santos, Wainer S. SilvaLandslides cause significant human and environmental damage, as well as unpredictable damage to structures and buildings. This paper presents the development and application of a web-based system for risk management in landslide-related emergency preparedness. This system allows for easy access to information, even in hard-to-reach regions, by integrating mobile internet devices, like cell phones and tablets, with GPS systems, without … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Jan 2017 · 7,543 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Slope Assessment Systems for Predicting Landslides of Cut Slopes in Granitic and Meta-sediment FormationsSuhaimi Jamaludin, Bujang B.K. Huat, Husaini OmarIn Malaysia, slope assessment systems (SAS) are widely used in assessing the instability of slope or the probability of occurrence and the likely severity of landslides. These SAS can be derived based on either one particular approach or combination of several approaches of landslide assessments and prediction. This study overviews four slope assessment systems (SAS) developed in Malaysia for predicting … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,909 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization and Geotechnical Properties of Penang Residual Soils with Emphasis on LandslidesFauziah Ahmad, Ahmad Shukri Yahaya, Mohd Ahmadullah FarooqiThe predominantly hilly terrain of Penang Island combined with average maximum daily temperatures ranging between 27-35°C and peak rainfall as high as 647 cm makes the overall area potentially susceptible to landslips. Over the recent past construction industry has shown a rapid growth mainly due to increase in the inflow of international tourists and other economic reasons. Eventually, the magnitude … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 8,230 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Slope Assessment System in Predicting Landslides along Roads Underlain by Granitic FormationBujang B.K. Huat, S. JamaludinA slope assessment is to estimate the probability of occurrence and likely severity of landslides in a given area. This study evaluates two existing Slope Assessment Systems (SAS) for predicting landslide at the micro level of assessment developed by the Public Works Department of Malaysia, namely the Slope Information Management System (SIMS) and the Slope Management and Risk Tracking System … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Forest and Extreme Gradient Boosting with Bayesian Hyperparameter Optimization for Landslide Susceptibility Mapping in Penang Island, MalaysiaDorothy Anak Martin Atok, Soo See Chai, Kok Luong Goh et al.Landslide susceptibility models often face challenges of overfitting and overestimation. This research focuses on improving the predictive capabilities of the Extreme Gradient Boosting (XGBoost) and Random Forest (RF) algorithms by applying Bayesian Hyperparameter Optimization (BayesOpt). Penang Island, a region in Malaysia prone to frequent landslides, was chosen as the study area. Ten Landslide Conditioning Factors (LCFs), including elevation, slope angle, … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 3,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractLandslide Susceptibility Mapping with GIS in Nagi Dada Area of Panauti Municipality, Kavrepalanchwok District: A Comparison Between AHP and FR MethodArju Bhattarai, HimLal Shrestha, Asim Timalsina et al.Landslide Susceptibility Maps (LSM) are useful for both development planning and disaster management. Currently, LSMs are primarily created using GIS and remote sensing techniques. Landslide susceptibility mapping relies heavily on selecting and weighting causative elements based on their impact on slope instability. GIS is useful for calculating static parameters such as slope and aspect, as well as generating landslide susceptibility … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 22 Aug 2024 · 7,093 accessesView PDFCite
Case ReportOpen accessIn the abstractComputational Analysis of Environmental Risk ConditionersBarbara Carla Coelho Batista, João Victor Dutra Balboa, Caio Vincenzo Reis Dima et al.The intense urbanization process since the 1970s, coupled with the lack of adequate housing and social policies, has led large urban centers to disordered occupations and situations of geotechnical risk. These occupations were not implemented in a technically correct manner from the point of view of civil engineering, considering landscaping, drainage and paving, as well as edification. Areas at risk … …American Journal of Environmental Sciences, Vol. 16, Issue 5 · 16 Oct 2020 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractLandslide Susceptibility Analysis Using Numerical and Neural Network, Near Kedarnath, Uttarakhand, IndiaVinay Kumar Singh, Tariq Anwar Ansari, Vikram Vishal, T.N. SinghThe major concern in hilly regions is the stability of those slopes, which have been proclaimed due to unplanned excavation and uneven blasting during road widening and development activity. These slopes again become more vulnerable under dynamic loading and/or various types of human involvement, heavy rainfall and seismic activity. Failure of these slopes leads to loss of property and human … …American Journal of Environmental Sciences, Vol. 16, Issue 1 · 9 Mar 2020 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of the Efficacy of Landslide Susceptibility ModelsJordan Henrique de Souza, Gislaine dos Santos, Gabriela Guimarães Gouvêa de Oliveira et al.This research aims to analyze the efficacy of SHALSTAB, IPT, SAGA, SMORPH and modified SMORPH models in evaluating landslide susceptibility. Statistical analysis concerning both the efficacy of the models in the prediction of landslide risks and the concordance between the models according to landslide occurrence or non-occurrence was performed. For this work, logistic regression, Receiver Operating Characteristic (ROC) curves, Kappa … …American Journal of Environmental Sciences, Vol. 15, Issue 3 · 31 May 2019 · 8,839 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA Satellites Help us to Quickly Detect Forest FiresRelly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.The main idea is that, as the forests of the planet are getting smaller, too much wood is cut and the forests are made too slow, there are also large forest fires due to excessive heat, of people arguing with the law, or simply by chance. Extinguishing fires are generally difficult, interventions being difficult anyway due to the increased fire, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 20 Feb 2018 · 8,085 accessesView PDFCite
