Geoelectrical characterization of fumarolic zones in the Cerro Machín volcanic dome

Mia Valentina Angulo Melendez · Manuel Alberto Florez Torres · José David Sanabria Gomez

Cerro Machín Volcano (Tolima, Colombia) is considered one of the most hazardous volcanic systems in the country due to its eruptive potential and the presence of an active fumarolic field on the central dome. Characterizing these surface manifestations is essential to understand the hydrothermal dynamics and the potent...

Regional Screening of Secure CO2 Geological Storage Beyond Oil and Gas Fields: A Criteria-based Assessment of Colombian Sedimentary Basins

Stephanie San Martín Cañas · Danna Valentina Hernández Giraldo · Boris Lora-Ariza · Leonardo David Donado

CO2 geological storage, a core component of CCS technologies, is a key pillar of climate change mitigation and the reduction of CO2 emissions within future low-carbon energy systems. Geological suitability constitutes the primary prerequisite for long-term to permanent subsurface CO2 containment. Consequently, the iden...

Bridging science and policy for geohazard management in Ibero-America through Geological and Mining Surveys

Roberto Sarro · Enrique Castellanos · Alejandro Celli · Mónica Marín David · y 16 más

Ibero-America ranks among the world’s most vulnerable regions to geohazards, where landslides, rockfalls, debris flows, earthquakes, and volcanic eruptions have caused not only severe economic losses, but also thousands of fatalities. In this context, the members of the Association of Ibero-America’s Geological and Min...

Molecular and Crystalline Structures in a Highly Irradiated Protoplanetary Disk in NGC 6357

María Alejandra Lemus Nemocon · María Claudia Ramírez-Tannus · Mario Armando Higuera Garzón

Understanding star and planet formation in extreme environments is crucial for uncovering the origins of our solar system. While most knowledge comes from nearby, isolated regions such as Taurus and Lupus, over half of all stars and planetary systems form in environments exposed to strong far-ultraviolet (FUV) radiatio...

Microplastic Occurrence in Relation to Sediment Granulometry Along the Central Caribbean Coast of Colombia

Nelson Rangel-Buitrago

Previous investigations along Colombia’s central Caribbean coast have documented microplastic (MP) pollution in terms of typology, abundance, and spatial distribution. However, the influence of sediment granulometry and associated statistical parameters (mean, median, sorting, skewness, and kurtosis) on MP occurrence r...

Grasslands and soil carbon: What can livestock management practices teach us? A global map of scientific knowledge

Camille Rousset · Luís mendes · Markus van der Meer · Julian Esteban Rivera · y 9 más

Grasslands represent a vast resource, covering >40% of the Earth’s land surface, supporting biodiversity, reducing erosion risks, and storing carbon (C) in soils. Yet they are increasingly threatened by land-use intensification, land degradation, and climate change. In response to these multiple pressures, numerous sci...

Investigating Pollutant-Meteorology Interactions In Urban Surface Layer Through UAV-Based Vertical Profiling

Uzma Nawaz · S.M. Shiva Nagendra · Devaprakash Muniraj

Understanding the vertical structure of aerosols near the surface is crucial for enhancing exposure assessment, validating air quality models, and characterizing boundary layer processes at fine spatial scales, as pollutant level varies significantly due to complex interactions between emissions and local atmospheric c...

From ductile shearing to brittle reactivation of a tectonic suture: The evolution of the Cauca–Romeral Fault System, Northern Andes

Laura Cristina Calderón Díaz · Sebastian Zapata · Agustín Cardona · Mauricio Parra · y 3 más

Andean-type orogens are characterized by prolonged subduction, in which the upper plate can record alternation between contractional and extensional phases. Subduction may involve the accretion of anomalies in the subducted slab, resulting in upper plate deformation and mountain building. The collision of the Caribbean...

Sustainable ultra-high-performance concrete: strength, durability, and carbon footprint with recycled glass and limestone

Joaquin Abellan-Garcia · M. Iqbal Khan · Yassir M. Abbas · Mohamed ElGawady

Revisiting the airshed concept in the tropics for assimilative capacity characterization.

Juan Cely · Carlos M. González · German Rueda-Saa · Rodrigo Jimenez

Air pollution has become a serious problem in developing countries due to industrial growth, poor understanding of the atmospheric circulation, weakly planned land use, and weakly enforced air pollution regulation. As part of this, the location of industrial emission clusters frequently does not account for air mass tr...
