Sediment dynamics and geohazards offshore Uruguay and northern Argentina: first results from the multi-disciplinary Meteor-cruise M78-3 [PDF]

open access: yes, 2010
About 90% of the sediments generated by weathering and erosion on land get finally deposited at the ocean margins. The sediment distribution processes and landscape evolution on land are relatively well understood, but comparably little is known about ...

Evaluation of Sediment Connectivity Indices to Improve the Prediction of the Spatiotemporal Variability of Sediment Yield for a Large River Basin (Wei River, China)

open access: yesLand Degradation &Development, Volume 37, Issue 8, Page 3406-3417, 15 May 2026.
ABSTRACT Sediment connectivity between source areas and the main streams or local sinks is a complex and dynamic process, especially in large basins due to multiple heterogeneities and interactions between connectivity components. Sediment connectivity indices are promising tools to investigate sediment transport, especially in data‐scarce or large ...

Submarine Landslide Identification Based on Improved DeepLabv3 with Spatial and Channel Attention

open access: yesRemote Sensing
As one of the most destructive, hazardous, and frequent marine geohazards, correctly recognizing submarine landslides holds substantial importance for regional risk assessment, disaster prevention, and marine resource development.

Sedimentological effects of tsunamis, with particular reference to impact-generated and volcanogenic waves [PDF]

open access: yes
Impulse-generated waves (tsunamis) may be produced, at varying scales and global recurrence intervals (RI), by several processes. Meteorite-water impacts will produce tsunamis, and asteroid-scale impacts with associated mega-tsunamis may occur.

Landslide susceptibility mapping using a machine learning approach and different environmental factors in the Western Ghats region (India)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Landslide susceptibility mapping in India's Western Ghats using machine learning revealed high‐risk zones driven by deforestation, slope alteration and road proximity. The Random Forest model showed highest accuracy, supporting targeted mitigation, planning and early warning systems.

Potential failure mechanism of low–angle submarine landslides in shelf–slope break of Pearl River Mouth Basin, South China Sea

open access: yesInternational Journal of Mining Science and Technology
Low–angle submarine landslides pose a greater threat to offshore infrastructure compared to those with steep sliding angles. Understanding the preparation and triggering mechanism of these low–angle submarine landslides remains a significant challenge ...

2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

Evaluation of Earthquake‐Induced Slope Displacements in Greater Vancouver Based on Probabilistic Framework and Using NBCC 2020 and EqDisp Code Platform

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
Engineers frequently use simplified seismic slope displacement procedures to evaluate the performance of earth structures and natural slopes. Current practices typically adopt Newmark‐type and semi‐empirical seismic displacement prediction models (SDPMs) to estimate the seismic slope displacements (D) based on ground motion intensity measures at a ...

Shallow-Water Submarine Landslide Susceptibility Map: The Example in a Sector of Capo d’Orlando Continental Margin (Southern Tyrrhenian Sea)

open access: yesJournal of Marine Science and Engineering
Active continental margins, generally characterized by narrow shelves incised by canyons, are pervasively shaped by submarine landslides that can occur near coastal areas.
