Analyzing the 27 July 2021 rainfall-induced catastrophic landslide event in the Kutupalong Rohingya Camp in Cox’s Bazar, Bangladesh Geoenviron. Disasters Pub Date : 2022-08-02 Kamal, A. S. M. Maksud, Hossain, Farhad, Ahmed, Bayes, Sammonds, Peter
This article critically investigates a catastrophic rainfall-induced landslide event that occurred on 27 July 2021 in the Kutupalong Rohingya Camp (KRC) in Cox’s Bazar, Bangladesh, from geological and geomorphological perspectives. Large-scale anthropogenic interventions mainly caused the disastrous landslide event in the KRC in addition to intense rainfall. Before the landslide occurrence, about 300 mm

The tale of three landslides in the Western Ghats, India: lessons to be learnt Geoenviron. Disasters Pub Date : 2022-07-13 Ajin, R. S., Nandakumar, D., Rajaneesh, A., Oommen, T., Ali, Yunus P., Sajinkumar, K. S.
In recent years, landslides have become a typical monsoon calamity in the Western Ghats region of Kerala, India. In addition to property damage, heavy rainfall (36% above normal) and multiple landslides (4728) killed 48 people in 2018. This tendency continued throughout the monsoon seasons of 2019, 2020, and 2021, resulting in the deaths of over 100 people. Anomalous precipitation is ascribed to the

Plugging efficiency of pouring aggregates through multiple boreholes into an inundated tunnel to prevent groundwater inrush disasters Geoenviron. Disasters Pub Date : 2022-07-07 Hui, Shuang, Sui, Wanghua, Zhang, Gailing, Chen, Jiaxing, Yu, Shibo
This paper presents an experimental investigation of the plugging efficiency of aggregate pouring through multiple boreholes under flowing water conditions into an inundated mine tunnel. Aggregate pouring into an inundated mine tunnel has been widely used and constitutes the premise for the salvage of flooded underground mines through further grouting. However, corresponding in-depth research is relatively

The 2019 Mw 7.0 Banten, Indonesia, intraslab earthquake: investigation of the coseismic slip, tsunami modelling and Coulomb stress change Geoenviron. Disasters Pub Date : 2022-06-10 Gunawan, Endra, Kongko, Widjo, Kholil, Munawar, Widyantoro, Bayu Triyogo, Widiyantoro, Sri, Supendi, Pepen, Hanifa, Nuraini Rahma, Anjasmara, Ira Mutiara, Pratama, Cecep, Gusman, Aditya Riadi
The 2019 Mw 7.0 Banten, Indonesia, earthquake occurred at a 49 km depth in a relatively unknown region, where the geological structure did not clearly show the fault. In this study, we use the Global Navigation Satellite System data to analyse the fault source of the earthquake. Following the earthquake’s focal mechanism, we modelled a total of four fault models using two possible fault strikes, with

Susceptibility areas identification and risk assessment of debris flow using the Flow-R model: a case study of Basu County of Tibet Geoenviron. Disasters Pub Date : 2022-06-06 Xu, Huange, Su, Peng, Chen, Qiong, Liu, Fenggui, Zhou, Qiang, Liu, Linshan
Uncertainties exist in the magnitude and outbreak of debris flow disasters, resulting in significant loss of lives and property to human society. Improved identification of debris flow susceptibility areas can help to predict the location and sphere of influence of debris flow disaster, thus accurately assessing the risk of debris flow disaster and reducing losses caused by such a disaster. The dry-hot

Runoff observation in a tropical Brantas watershed as observed from long-term globally available TerraClimate data 2001–2020 Geoenviron. Disasters Pub Date : 2022-06-02 Wiwoho, Bagus Setiabudi, Astuti, Ike Sari
Runoff information and its dynamics are critical for supporting watershed management; however, spatio-temporal data about runoff is rare or unavailable in data-scarce regions. Information about the performance of remote sensing-based runoff and its potential application is limitedly known. In data-scarce regions, this condition impedes comprehensive watershed assessment especially in the midst of climate
