Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

RT‐FAIRS: Real‐Time Factor‐Adjusted Ionospheric Residual Statistics Approach for Generating Accuracy Information in Global Ionospheric Maps

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Ionospheric delays remain a major error source in Global Navigation Satellite Systems (GNSS). The International GNSS Service (IGS) provides Global Ionospheric Maps (GIMs) that offer vertical total electron content (VTEC) estimates together with RMS maps as accuracy information.

The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed geomagnetic conditions.

A Multisensor Remote Sensing Approach to Archaeological Prospection: Integrating UAV and Google Earth Data in the Bayan Gol Valley, Mongolia

Archaeological Prospection, Volume 33, Issue 1, Page 109-130, January/March 2026.
ABSTRACT This study investigates the effectiveness of drone‐based remote sensing and Google Earth satellite imagery for archaeological prospection in the Bayan Gol Valley, Central Mongolia. Utilizing a fixed‐wing unmanned aerial vehicle (UAV) equipped with RGB and multispectral sensors, we surveyed 655 ha to document Mongol‐period settlement structures

Thermal drone observations capture fine‐scale population decline of short‐tailed shearwaters

Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 773-789, December 2025.
Researchers used thermal drone technology to monitor short‐tailed shearwater colonies in Tasmania from 2019 to 2024, discovering a concerning 27% decline in chick numbers during this period. The study estimates that the global population of these seabirds has dropped dramatically by 41% since 1985, falling from 23 million to approximately 13.5 million ...

Validation of Regional Positioning Service User Connections as Support in Update Cartography

Transactions in GIS, Volume 29, Issue 1, February 2025.
ABSTRACT The significant demand for highly updated geospatial or cartographic information surpasses the capacity of the official agencies responsible for its generation. The procedure for updating official cartography, in some Spanish regions, can take more than three or 4 years.
