Earth and Space Science, Volume 11, Issue 10, October 2024.Abstract We calculate focal mechanisms and centroid depths for deep‐focus earthquakes (DFEs) along the Peru‐Brazil border. We obtained a total of 28 focal solutions for events with magnitudes between 4.2 and 7.5 Mw and occurring between 2014 and 2022.

Effects of trade and poaching pressure on extinction risk for cacti in the Atacama Desert
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract In this era of a global biodiversity crisis, vascular plants are facing unprecedented extinction rates. We conducted an assessment of the extinction risk of 32 species and 7 subspecies of Copiapoa, a genus endemic to Chile's fog‐dependent coastal Atacama Desert.

Global Change Biology, Volume 30, Issue 10, October 2024.Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.

Why Is the Dust Activity in the Atacama Desert Low Despite its Aridity?
Journal of Geophysical Research: Atmospheres, Volume 129, Issue 16, 28 August 2024.Abstract The Atacama Desert is amongst the driest places on Earth yet large dust outbreaks seem rare. We present the first quantitative assessment of dust events in the Atacama for 1950–2021 based on station observations. A total of 1920 dust days were recorded with less than 10% being classified as dust storms. We calculated the wind speeds at 5%, 25%
