This study sought to assess the influence of causal factors related to anthropogenic activities on landslide occurrence in Bukit Antarabangsa, a township northeast of Kuala Lumpur in Ampang Jaya Municipal Council. Anthropogenic factors were chosen based on the township’s rapid growth, numerous landslide records and intensity of hillside development. The study used a data-driven statistical model to identify factors most predictive of landslide occurrence based on an inventory of 20 landslides, and to evaluate the extent to which susceptibility was driven by factors related to urban development. A total of 17 factors were categorized into four clusters (geological, geomorphological, hydro-tographical and anthropogenic). Factor maps were classified to derive factor classes for each parameter. The dataset was then processed using a weight-of-evidence statistical model to determine the contrast value of each factor class. Contrast value (C) reflects the extent to which each factor class predicts landslide occurrence. The C-weighted factor maps were then combined to derive the landslide susceptibility index (LSI). The LSI enabled visualization of the spatial distribution of susceptibility based on a given combination of factors. Susceptibility maps were prepared for combinations containing only non-anthropogenic parameters and all landslide parameters. The study compared these combinations to determine the influence of anthropogenic factors on total LSI. Similar analyses were conducted to determine the effect of each anthropogenic factor on LSI. The results indicated that lineament density, distance to lineament and distance to road had a significant influence on landslide occurrence. A strong correlation with landslide occurrence was observed for land use/land cover, especially in high susceptibility zones, followed closely by the influence of one distance to road factor class. The results could be useful in planning infrastructure corridors in densely built-up landslide-prone areas.

Human-induced landslides at bukit antarabangsa, hulu kelang, Selangor

This study revisits the Bukit Antarabangsa, a hilly topographic region of Ampang Jaya where a number of landslides occurred between year 1990 and 2010, resulted in 65 lives perished. Among those fatal landslides were the collapsed of a block of Highland Towers condominium, Taman Hillview bungalow and Taman Bukit Mewah housing estate. In examining historical cases of the area from regional perspective and new supplementary data, there were numerous evidences showing the lands had been greatly battered and modified since the last 50 years before the fatal landslides occurred. It was found these extensive land exploitation, specifically long duration of exposed barren land until construction completed; construction practices; and construction on old landslides or previously modified sloping lands, had significantly contributed to the causal factor of the landslides. The humid tropical and fertile soil in Malaysia that promotes thick vegetation regrowth to the extent of resembling a primary forest-cover might have hindered detection of modified lands during for new construction. Thus, this study suggested that, in addition to climatic-induced and geological factors namely weathered granitic terrain and lithological relicts as predisposing factors, these landslides were also attributed by human disturbed terrain from multiple land-use changes. The site is an example of human-induced landslide disasters from the consequence of land use management and during-construction practices.

This research is aim to identify the impact of landslide on property market. Bukit Antarabangsa has been chosen as the case study. The data for this research were obtained using two methods, literature review and quantitative analysis approach. The questionnaire was designed to test the existing knowledge on landslide, to identify the level of awareness towards landslide and the perception of house buyers towards landslide prone area. The sample was selected from Bukit Antarabangsa and its surrounding neighbourhood. Descriptive analysis was used to analyse the data obtained statistic through frequency, percentage and cross tabulation. Pie chart, graph and table are used to illustrate the data obtained. Correlation method is used to identify the relation between variables. The data are also explained and correlated with the previous research. The results revealed that the level of awareness and understanding towards landslide among the house buyer have been increased due to sufficient amount of knowledge with regards to landslide. People are showing positive attitude towards landslide prone area despite knowing the risk of a territory with such condition. People believe that the current market condition is stable and they continue to invest in landslide prone area.

A Study on the Contributing Factors of Major Landslides in Malaysia

Landslide is one of the most prominent geo-hazard that accounts for colossal losses every year. The contributing factors of landslides in Malaysia are reasonably different from rest of the world. According to a study, the most dominant factor that catalysis the slope failure in many countries of the world is geological conditions. However, in case of Malaysia; most of the landslides occur as a consequence of flawed design, improper construction and non-maintenance of slopes which correlates with the human errors. The statistics of Malaysia shows that highest number of landslides took place in 1996 with 71 cases which is followed by 68 cases in 1995. According to the findings of Highland Towers (1993) landslide, the main causes of failure were inaccuracies in design, poor supervision during the construction and inadequate drainage system. Similarly, in case of Taman Hillview and Bukit Antarabangsa landslide, it has been revealed that improper design practices and poor drainage system supplemented with prolonged rain were the significant causes of t he cataclysm. Therefore, based on the investigations on retrospective landslides, this study proposes to incorporate Human Reliability Assessment technique as a part of working strategy for slopes along with strong adherence to the design guidelines in order to minimize the likelihood of landslides.

Landslide issues in Malaysia is successfully attract the interest and attention of stakeholders and the community of scientists to reduce the risk. Landslides are influenced by many factors that range from the intensity, duration and extent of a triggering factor (e.g. earthquake and rainfall) to the local physical conditions such as landform, morphological, geological materials and structures, hydrological and land uses. In this paper, we present the results of the Landslide Vulnerability Assessment (LVAs). 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 0 (no loss) to 1 (total loss). The selection of the best LVAs depends on the exposed elements, landslide types and the scale of analysis. The concept of LVAs also refers to the feasibility of elements at risks on engineering structures, infrastructure facilities, communication systems, ...

Rainfall-induced landslides are very common in Malaysia especially during rainy seasons. Some of these landslides have resulted in not only extensive damage to properties but also loss of lives. An investigation has been carried out on one of the major landslides which occurred in Hulu Klang, known to be a landslide-prone area. The study involved: (i) determination of mode and mechanism of failure based on information from site investigation, field data collections and eyewitness accounts, (ii) back analyses and (iii) identification of contributing factors. The failure can be classified as a deep-seated failure caused by existence of high pore-water pressure within the slope. The landslide may be attributed to a combination of factors such as: existence of loose soil from earth dumping on the slope which took place during the development of the area, prolonged rainfall during the months of October and November, widening of existing cracks and opening of new tension cracks due to pro...

In recent years Malaysian government has started to pay more attention to the landslide issues, as public outcries grew louder. Some local authorities that are at the front line of public anger whenever major landslides occurred have yet to provide better services while others utilized guidelines and relevant acts to act against errant developers and land owners. As a consequence of this, Public Works Department (PWD) and its Slope Engineering Branch (CKC) will require training, not only in the procedures themselves, but also in regards to the basis of landslide mechanisms, landslide risk assessment and dealing with geotechnical reports at best professional manner. In addition to the success of implementing for the National Slope Master Plan NSMP 2009-2023 would depend on every stakeholder and relevant authorities that includes the public residents and most of all the political parties of the Malaysian government and it is therefore local government and other regulators must establi...

Inceasing demand for housing and infrastructure in Penang Island has forced development to expand into hillslope areas susceptible to geohazards such as landslides. Over the past few years landslide events have resulted in heightened concern for public safety. Development projects, many of which are of high-rise and high-density ventures, is increasingly approved on sensitive land with a history of landslide events. A field trip was conducted on 20 September 2018 involving 24 participants from various institutions to gain insights from selected development projects that are at risk of landslides. The focus was on hillslope areas at Tanjung Bungah and a road construction site at Paya Terubong. The field visit reaffirmed the importance of geoscience for land development, to identify areas susceptible to landslides and provide appropriate information for effective engineering solutions. With the advent of climate change, the country is now experiencing a rise in extreme weather phenomena, which may increase the occurrence of climate-influenced geohazards including landslides. Geoscientists have to take a more active role in reducing risks associated with geohazards, to protect communities from future disasters and ensure sustainable development.

In Kuala Lumpur to date, there is little evidence to support landslide causes and very little research into the nature of landslide vulnerability. This article takes an interdisciplinary method and empirical approaches to examine, in addition where necessary, challenge a series of assumptions made regarding Landslide Risk Management (LRM) with a view to developing better understanding of social vulnerability on landslide hazard and its underlying causes alongside combine expert judgment on triggering factors. Moreover, the contribution of Malaysia Public Works Department (PWD/JKR) via the implication of National Slope Master Plan (NSMP 2009-2023) operational capabilities and its effectiveness on landslide risk mitigation measures is reviewed. The finding on the influence of landslide causative and triggering factors have shown steepness of slope was greatly functioned as a landslide primary causative factor on mass movement whereas, in Kuala Lumpur rainfall and human activities plays significant role in triggering landslide on a slope vulnerable to failure. The result suggests occupants of landslide prone areas have decent perceptions of landslide and its associated risk. Contrary wise, a loss of confidence by local residents on government authorities on implementing appropriate hazard mitigation measures, lack of voluntary data sharing and insufficiency public awareness campaigns conducted by Malaysian local authorities. Abstrak Di Kuala Lumpur sehingga kini, terdapat sedikit bukti kajian yang menyokong punca kejadian tanah runtuh dan kekurangan penyelidikan yang mengkaji sifat kerentanan tanah runtuh. Kajian ini mengambil pendekatan antara disiplin dan kaedah empirikal untuk memeriksa dan, sekiranya perlu, mencabar andaian-andaian yang dibuat dalam Pengurusan Risiko Tanah Runtuh (LRM) dengan tujuan untuk membentuk pemahaman yang lebih baik terhadap kerentanan sosial kepada bahaya tanah runtuh dan faktor penyebab asas, di samping menggabungkan pendapat pakar terhadap faktor pencetus. Selain itu, sumbangan Jabatan Kerja Raya Malaysia (JKR) menerusi Pelan Induk Cerun Negara (NSMP 2009-2023) serta implikasi ke atas keupayaan operasi dan keberkesanannya kepada langkah-langkah pengurangan risiko tanah runtuh turut disemak. Hasil kajian ke atas pengaruh faktor tanah runtuh dan faktor pencetus mendapati faktor kecuraman cerun merupakan faktor penyebab utama tanah runtuh, manakala di Kuala Lumpur hujan dan aktiviti manusia memainkan peranan penting dalam mencetuskan runtuhan di cerun berisiko. Hasil kajian turut menunjukkan penghuni di kawasan cenderung berlaku tanah runtuh mempunyai kesedaran dan persepsi risiko yang baik terhadap tanah runtuh dan risiko yang berkaitan. Sebaliknya, penduduk tempatan kehilangan keyakinan terhadap pihak berkuasa kerajaan untuk melaksanakan langkah-langkah mitigasi pengurangan bahaya ekoran kekurangan perkongsian data secara sukarela dan kekurangan kempen kesedaran awam yang dianjurkan oleh pihak berkuasa tempatan di Malaysia. Katakunci: Kuala Lumpur, Pengurusan Risiko Tanah Runtuh (LRM), kerentanan tanah runtuh, Pelan Induk Cerun Negara (NSMP), langkah mitigasi
