Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

Multi‐Scale Intense Geoelectric and Geomagnetic Field Perturbations Observed After an Interplanetary Magnetic Field Turning

Space Weather
Intense geoelectric fields during geomagnetic storms generate geomagnetically induced currents in power grids and other infrastructure, necessitating an understanding of their causes, for example, through coordinated space and ground observations.

The New Geomagnetic Monitoring Network in China: Insights From the 2024 Mother's Day Superstorm

Space Weather, Volume 24, Issue 2, February 2026.
Abstract China has established a ground‐based network system, that is the Chinese Meridian Project (CMP), to continuously monitor the geomagnetic field. The superstorm in May 2024 was analyzed using the CMP data. The negative peak of the horizontal geomagnetic field (Bh) during the storm main phase at different CMP stations varied between −449 nT and ...
