Comprehensive Inventory of Coseismic Landslides Triggered by the 2023 Kahramanmaraş Earthquakes, Türkiye

Abdüssamet Yılmaz, Hakan Tanyaş, Furkan Karabacak, Mehmet Lutfi Süzen et autres

Abstract We provide two geospatial inventories covering ~80,000 km² in southern Türkiye for the 6 February 2023 Kahramanmaraş earthquake sequence: (i) a coseismic landslide polygon inventory including 20,270 landslides and (ii) a pre-earthquake geomorphic inventory of pre-existing slope instability including 4,495 landslide …

Modeling the combined effects of the 2023 Türkiye–Syria earthquake and an Atmospheric River event on landslide hazard

Hunter N. Jimenez, Erkan İstanbulluoğlu, Tolga Görüm, Thomas A. Stanley et autres

Abstract. This study investigates the landslide hazards resulting from the compound effects of the February 6, 2023 Türkiye-Syria earthquakes and a subsequent atmospheric river (AR) event that delivered up to 183 mm of rainfall across the earthquake-impacted region. Using the open-source Landlab …

New and existing settlements built on hillslopes weakened by the 2023 Kahramanmaraş earthquake sequence

Yu Wang, Ashok Dahal, Cees J. Van Westen, Tolga Görüm et autres

After major earthquakes, reconstruction and resettlement decisions are often made without fully accounting for cascading hazards, exposing communities to landslide risk. Strong ground shaking can alter hillslope mechanics, yet regional patterns of post-seismic strength change remain poorly constrained. Here we present a …

Coseismic InSAR reveals stronger topographic amplification proxies far from faults

Congwei Yu, Ashok Dahal, Islam Fadel, Atilla Arda Özacar et autres

This dataset contains the D-InSAR data generated in this study (D-InSAR.zip), the processing code for generating slopeunits, calculating coseismic deformation on upper and lower slopes and their topographic amplification (TA) in pre-processing.zip, and the nine data matrics (datamatrics.zip) made from these procedures, …

Estimating Hillslope-Scale Topographic Amplification from Space

Hakan Tanyaş, Congwei Yu, Islam Fadel, Ashok Dahal et autres

Topographic amplification (TA) alters seismic-wave propagation and can intensify ground shaking and earthquake damage. Yet observational assessments of TA remain largely constrained to hillslope and regional scales, and spatially varying TA footprints are still documented primarily through earthquake simulations rather than direct …

INTEGRATING LANDSLIDE AND LIQUEFACTION HAZARD AND LOSS ESTIMATES WITH EXISTING USGS REAL-TIME EARTHQUAKE INFORMATION PRODUCTS

Kate E. Allstadt, Michael G. Hearne, M. Anna Nowicki Jessee, Jinyang Zhu et autres

The U.S. Geological Survey (USGS) has made significant progress toward the rapid estimation of shaking and shaking-related losses through their Did You Feel It? (DYFI), ShakeMap, ShakeCast, and PAGER products. However, quantitative estimates of the extent and severity of secondary hazards (e.g., …

Forecasting InSAR-derived slope movement from climate records at Baihetan reservoir

Jiawei Dun, Jun He, Luigi Lombardo, Ling Chang et autres

Interferometric Synthetic Aperture Radar (InSAR) has become a powerful tool for monitoring hillslope deformation. Recent advances have focused on integrating InSAR with predictive models, yet limited effort has been dedicated to developing scenario-based prediction of hillslope deformation informed by climatological records to …

Do Earthquakes Wake More Slopes Than They Calm?

Ashok Dahal, Hakan Tanyaş, Alexander L. Handwerger, Luigi Lombardo et autres

Strong earthquakes can have a dual impact on the slow-moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional-scale influence on hillslope processes remains poorly understood due to limited observational coverage and …
