2022 Tonga Volcanic Eruption Induced Global Propagation of Ionospheric Disturbances via Lamb Waves

Frontiers in Astronomy and Space Sciences, 2022
The Tonga volcano eruption at 04:14:45 UT on 2022-01-15 released enormous amounts of energy into the atmosphere, triggering very significant geophysical variations not only in the immediate proximity of the epicenter but also globally across the whole ...

Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate ...

Karst, GIS and geological hazard planning and management in Great Britain [PDF]

, 2010
The British Geological Survey (BGS) database of karst features for the United Kingdom include dolines, cave entrances, stream sinks, resurgences and building damage; data for approximately half of the country has so far been gathered.

Effects of test conditions on shear behaviour of composite soil [PDF]

, 2013
Test conditions, such as shearing rate and normal stress, have been long recognised as influencing the measured shear strength of clays and sands. However, their influence on composite soils, which have a wide range of particle sizes, has attracted much ...

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

Land Degradation &Development, Volume 37, Issue 4, Page 1330-1352, 28 February 2026.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

New Analytical Model for Forecasting Turbidity Current Run‐Up Heights: Implications for Risk Assessment of Seafloor Infrastructure on Submarine Slopes

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Turbidity currents are destructive flows that are hazardous to critical seafloor infrastructure on submarine slopes because run‐up heights can be 10–100s of meters, as their relative density is 2–3 orders of magnitude lower than terrestrial flows. Currently, risk analysis is hindered by poor prediction of run‐up heights that are mainly derived

Geohazard susceptibility mapping considering spatial heterogeneity: a case study of Xide County in Sichuan Province

Natural Hazards
Spatial heterogeneity has a significant effect on the efficiency of geohazard susceptibility mapping. Taking Xide County in Sichuan Province as an example, a semi-quantitative zoning scheme based on the hazard-pregnant environment is proposed.

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Integrating Geoscience, Ethics, and Community Resilience: Lessons from the Etna 2018 Earthquake

Geosciences
Mount Etna has a well-documented history of frequent eruptions and seismic activity, periodically causing significant damage to urban areas. On 26 December 2018, a Mw 4.9 shallow earthquake struck the volcano’s eastern flank, severely damaging ...
