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.

Uncovering the key bilateral trade linkages in the U.S. domestic food supply chain through disruption simulations

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This paper uses counterfactual simulations to examine the impact of bilateral trade linkage disruptions on the U.S. agricultural and food trade system. Using an econometric gravity model, we estimate the relationship between disruptions and trade flows, identify critical state‐to‐state trade linkages whose disruption would significantly impact

Slider-Block Friction Model for Landslides: Application to Vaiont and La Clapiere Landslides [PDF]

, 2003
Accelerating displacements preceding some catastrophic landslides have been found empirically to follow a time-to-failure power law, corresponding to a finite-time singularity of the velocity $v \sim 1/(t_c-t)$ [{\it Voight}, 1988].

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, EarlyView.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Dynamics and Deposits of Pyroclastic Density Currents in Magmatic and Phreatomagmatic Eruptions Revealed by a Two‐Layer Depth‐Averaged Model

Geophysical Research Letters, 2023
A pyroclastic density current (PDC) is characterized by its strong stratification of particle concentration; it consists of upper dilute and lower dense currents, which generally control the dynamics and deposits of PDCs, respectively.

Earthquake‐induced landslide scenarios for seismic microzonation. Application to the Accumoli area (Rieti, Italy) [PDF]

, 2019
Scenarios of earthquake-induced landslides are necessary for seismic microzonation (SM) studies since they must be integrated with the mapping of instability areas.

Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, EarlyView.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Landslide Risk: Economic Valuation in the North-Eastern Zone of Medellin City [PDF]

, 2017
Natural disasters of a geodynamic nature can cause enormous economic and human losses. The economic costs of a landslide disaster include relocation of communities and physical repair of urban infrastructure.

Projected 21st Century Changes in Precipitation and Temperature Over Italy Using CMIP6 CMCC‐CM2‐SR5 Model and COSMO‐CLM Dynamical Downscaling

International Journal of Climatology, EarlyView.
This study evaluates the COSMO‐CLM regional climate model over Italy under CMIP6 scenarios. Compared to its driving global model, COSMO‐CLM reduces temperature biases by 50%–75% and better represents precipitation and extremes, adding critical mesoscale detail.

An approach for real-time monitoring of hydrological risk hotspots during extreme rainfall events

Geomatics, Natural Hazards & Risk
Real-time monitoring of hydrological risk hotspots during extreme rainfall events is limited by certain challenges. Here, we introduce a new approach for tracking such hotspots across large areas in real time.
