It resulted in approximately 8800 deaths, tens of thousands of injuries, and hundreds of thousands of destroyed buildings. The earthquake also triggered extensive landsliding. This research summarizes the findings of an inventory of more than 13,000 seismically induced landslides that occurred in the districts Rasuwa, Nuwakot, Dhading, and Sindhupalchok, located north of Kathmandu. The landslide inventory was developed by comparing pre- and postearthquake digital satellite imagery (Google Earth Pro) and targeted ground-truthing during postearthquake field reconnaissance studies. Identified landslides were then imported to GIS to ascertain the impact of contributing factors such as slope steepness, elevation, and aspect, along with soil type and peak ground acceleration.</p><p><b>Bestandsaufnahme der Hangrutschungen in Folge des 2015 Gorkha (Nepal) Erdbebens</b></p><p>Das Mw 7,8 Gorkha (Nepal) Erdbeben vom 25.

Three major rock avalanches have occurred since the last glaciation and ongoing rockfall from the head scarp area presently affects local infrastructure. This study presents geological and geomechanical investigations of Pletzachkogel that were performed using conventional and uncrewed aerial vehicle (UAV) mapping techniques and focused on understanding the different landslide processes. The investigation indicates that the gravitational instability is related to a stratigraphic sequence of “Hard on Soft” rock units: Hauptdolomit and Plattenkalk beds (hard) – Kössen Formation (soft) – Oberrhätkalk and Lower Jurassic Breccia units (hard). “Hard on Soft” slope deformation has been described for similar stratigraphic conditions and involves the overlying hard rock mass breaking apart over a soft underlying unit. This leads to distinct geomorphological features like buttresses. In addition to the “Hard on Soft” stratigraphy, synsedimentary deformation during deposition, polyphase, heteroaxial, tectonic deformation during Alpine orogenesis, and glacial loading and unloading during the last ice age exacerbated landslide processes. This study describes the “Hard on Soft” geomechanics of Pletzachkogel and also demonstrates the value of UAV-based structural mapping, particularly for acquiring and quantifying structural rock mass data in inaccessible areas.</p>","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"18 3","pages":"188-198"},"PeriodicalIF":0.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inherent variability in geologic and hydraulic conditions can make reliable scour prediction difficult such that historically, research and scour assessment tools have focused on simplified, idealized situations. This makes extension to more complex, site-specific conditions difficult. The rapidly expanding field of remote sensing technology (such as lidar, photogrammetry/structure from motion (SfM), multibeam sonar, and even video) in addition to the use of 3D digitally generated rock mass models has permitted the most detailed view to date into the site-specific characteristics of rock scour and provides the promise of improved state-of-the-art scour prediction models.</p><p><b>Erosionsanfälligkeit von Gesteinen in einer digitalen Welt: Fortschrittliche Technologien durch hochauflösende Fernerkundungstechnologie und digitale Gesteinsmassengenerierung</b></p><p>Die Erosion von Gestein ist ein kritisches Problem für Dämme, Überläufe und andere Wassertransportstrukturen, das im Falle eines Strukturversagens zu kostspieligen Schäden oder sogar zum Verlust von Menschenleben führen kann.
