Due to its persistent activity, the volcano is actively monitored and researched, and understanding the patterns of behaviour is vital to accurate hazard assessment.\u0000 \u0000 \u0000 Sentinel-1 SAR images from ascending and descending orbits allow 1D and 2D ground motions to be retrieved using multi-interferogram techniques. SqueeSAR\u0000 ®\u0000 ’s unique processing allows a better characterisation of subtle ground movements in remote, rural mountainous areas compared to many other multi-interferogram techniques. A dataset of 147 SAR scenes (2017-2019) has been processed to show patterns of lava subsidence (<150 mm of downward vertical deformation over 2 years), as well as volcano deflation and apparent westward lateral movement. These data indicate that viscous andesitic lava flows may remain mobile for years following eruption and emplacement, and that the entire volcanic edifice is subsiding.\u0000 \u0000 Despite the apparent quiescence, volcanic edifices can remain highly dynamic after the termination of explosive or effusive activity.

The disaster occurred on the northern slope of Mount Gunung Telagalele and caused more than 100 fatalities, leading to the most disastrous landslide in Indonesia during the last decades. The event is characterized by multiple slope failures forming two landslide events A and B, with two connected scarps but two separated runout paths. According to eyewitnesses, landslide A was mobilized only a few minutes after the initial failure of B. Initially, both landslides began as earth slides which subsequently developed into very to extremely rapid earth flows. Although the failure volume was moderate, both slide-flows reached very high velocities of several m/s and long travel distances, leading to remarkable low travel angles of 14 and 15°. Field investigations confirm that slope failure was favoured by geological predisposition based on a slope-parallel layering of volcaniclastic sediments of different origin and age, as well as intensive tropical weathering generating clay-rich soils. Temporal relationships as well as stability analysis indicate that antecedent rainfall over two months and heavy rainfall the day before was triggering the slope failure.\u0000 \u0000 Thematic collection:\u0000 This article is part of the Leading to innovative engineering geology practices collection available at:\u0000 https://www.lyellcollection.org/topic/collections/leading-to-innovative-engineering-geology-practices\u0000","PeriodicalId":20937,"journal":{"name":"Quarterly Journal of Engineering Geology and Hydrogeology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49397662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the architecture of CNN is proposed to predict the spatial distributions of hydraulic conductivity based on limited geologic factors. The performance of CNN model is evaluated using the new data of hydraulic conductivity. A comparative study with the empirical method is performed to validate the reliability of CNN model. The effect of weathering and unloading on the spatial distributions of hydraulic conductivity is studied using the CNN model. The result shows that the hydraulic conductivity predicted by CNN model is within the error range of 5% compared to the Lugeon borehole tests. The predictive accuracy of the CNN method is higher than the estimations of the empirical relations. The spatial distributions of hydraulic conductivity versus depth can be divided into three stages. At first stage, the hydraulic conductivity is slightly reduced with the increasing of depth. Increasing to the depth range of 300-600 m (second stage), the hydraulic conductivity is slightly reduced as a function of lower weathering degree. At last stage, the hydraulic conductivity is not changed by the weathering, and converge to a constant with the depth increasing.","PeriodicalId":20937,"journal":{"name":"Quarterly Journal of Engineering Geology and Hydrogeology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48775419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
