Insights Into Seismic‐Induced Ionospheric Perturbation Following the 2025 Myanmar Earthquake
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract A major earthquake with a magnitude of MW = 7.7, followed by several aftershocks, occurred in Mandalay, Myanmar, on 28 March 2025. This study aims to report on the co‐seismic ionospheric disturbances caused by the event, based on a multi‐instrument approach that was adopted to examine co‐seismic effects.

Space Weather, Volume 23, Issue 11, November 2025.Abstract Relativistic electrons are an important space weather hazard, being a major source of radiation damage to satellites and posing a risk to humans in space. We use approximately 20 years of data from the US Global Positioning System (GPS) satellite NS41 to determine the characteristics of the geomagnetic storms that lead to the largest ...

Space Weather, Volume 23, Issue 11, November 2025.Abstract Satellite navigation systems are vulnerable to space weather disturbances, which can degrade positioning accuracy and potentially increase the collision risk of unmanned aerial vehicles (UAVs). This study investigates the influence of navigation errors caused by ionospheric scintillation on UAV encounter scenarios. Two route configurations are

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 26, Page 4465-4484, 7 November 2025.Abstract Large‐scale water‐related concrete structures, such as dams, inevitably develop defects over time. Traditional manual inspections are inefficient, hazardous, and prone to high false detection rates. Unmanned aerial vehicles (UAVs) equipped with high‐resolution cameras provide a safer and more efficient alternative.
