“Cold Tropics”: Permafrost Existence and Thickness on Eastern Nevado Coropuna (Southern Peruvian Andes) Revealed by Ground‐Penetrating Radar and Geoelectrical Soundings

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 517-534, July/September 2026.
ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

An Approximate Time‐Domain Solution for Recharge Propagation Through Thick Unsaturated Zones

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study presents a time‐domain analytical solution for modelling groundwater recharge through thick unsaturated zones, applied to the Urucuia aquifer in Brazil. The model was calibrated using observed well data, capturing the attenuation of seasonal groundwater level fluctuations with depth.

Low Hazard–High Risk: A Case Study of the Active Mangatangi Fault

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Activity on low deformation rate faults are challenging to quantify and comparatively understudied. One such fault, the Mangatangi Fault, strikes NE‐SW along the southeastern flanks of the Hunua Ranges c. 52 km south of New Zealand's most populous city, Auckland.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
