Machine‐learning approaches for characterizing the raindrop size distributions in Western Pacific tropical cyclones

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...

Dynamics of Long-Runout Landslides: A Review

open access: yesApplied Sciences
Long-runout landslides usually cause a significant loss of life and property because of their hypermobility and immense energy to travel long distances at high velocities, attracting a global focus on the dynamics and mechanism of long-runout landslides.

Improving forest age estimation to understand subtropical forest regrowth dynamics using deep learning image segmentation of time‐series historical aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Accurately estimating forest age is key to understanding how forests recover and evaluating restoration success. We developed a two‐step deep learning approach using historical greyscale aerial photographs to map forest age at fine spatial scales. By combining a pre‐trained model with localized fine‐tuning, our U‐Net + ResNet50 architecture achieved ...

Landslides

open access: yesDisaster Prevention and Management: An International Journal, 2001
Canada has a wide range of landslides reflecting the diverse geological and geomorphological environments in the nation's landscape. Rock avalanches and rockfalls are extremely rapid landslides that are common in mountainous regions. Debris avalanches and channelized debris flows, typically triggered by heavy rains, form another group of rapid ...

Urban Forests and Environmental Challenges in the Last Decades in Brazil: Insights for the National Urban Forestry Plan

open access: yesSustainable Development, EarlyView.
ABSTRACT National afforestation policies are crucial for outlining guidelines and goals to be implemented at the local level. Therefore, it is crucial to conduct research that systematizes indicators from across the country into a single proposal. This study examines the spatiotemporal distribution of urban forest research in Brazil from 1980 to 2020 ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Mobilising Community Engagement in Disaster Risk‐Sensitive Urban Planning: Insights From Grounded Theory and Two‐Mode Social Network Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the emphasis in sustainable development goals (SDG) 11, 13, and 17 on collaborative efforts to address climate change‐induced disaster risks through inclusive planning, stakeholders' role in fostering community engagement in risk‐sensitive urban planning (RSUP) remains underexplored.

Mapping UK hazards [PDF]

open access: yes, 2010
The BGS has a 175-year history of mapping and recording geology including unstable land. However, public awareness of such potential problems was not awakened until the Aberfan disaster, 44 years ago, when a school was buried by a landslide from a coal
