Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Mapping landslide susceptibility at national scale by spatial multi-criteria evaluation

Geomatics, Natural Hazards & Risk, 2021
The representation of terrain propensity to generate landslides, meaning the mapping of landslide susceptibility, represents a first step in the assessment of the risk induced by these geomorphological hazards.

Landslide Susceptibility Mapping along the Anninghe Fault Zone in China using SVM and ACO-PSO-SVM Models [PDF]

, 2022
In the present study, a hybrid machine learning model was designed by integrating ant colony optimization (ACO), particle swarm optimization (PSO), and support vector machine (SVM) algorithms. The model was used to map the landslide susceptibility of the

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

Geological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Influence of Landslide Activity Characteristics on Landslide Susceptibility Assessment: A Case Study in the Upper Jinsha River

Remote Sensing
The geological environment is characterized by continuous dynamic changes. Landslide activity characteristics can reflect the geological environmental background that affects the landslide development in different historical periods.

Landslide susceptibility assessment based on the SOM-I-SVM model

Shuiwen dizhi gongcheng dizhi, 2023
When using machine learning models for landslide susceptibility evaluation, the non-landslide sample points are usually selected randomly outside the landslide influence area, leading to a certain error.

Assessing Landslide Damming susceptibility in Central Asia

Natural Hazards and Earth System Sciences, 2023
Abstract. Central Asia regions are characterized by active tectonics, high mountain chains with extreme topography with glaciers and strong seasonal rainfall events. These key predisposing factors make large landslides a serious natural threat in the area, causing several casualties every year.

Winegrowers' Perceptions and Adoption of Sustainable Soil Management Practices and Technologies: A Case Study in Piedmont, Italy

Land Degradation &Development, EarlyView.
ABSTRACT Soil is crucial for human survival but is threatened by erosion and contamination. Farmers play a pivotal role in soil conservation, thus, understanding what influences their decisions is crucial. The IN‐GEST SOIL project aimed to mitigate soil erosion and improve soil and vine quality in Piedmont vineyards, NW Italy.
