Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-71536-3 CO2-rich magmas beneath Pagan Volcano are stored near Moho depths and ascend to the surface within weeks to months. These findings link deep, rapid magma ascent to carbonate capped seamount subduction and highlight the role of recycled carbon in arc volcanism.

A massive movement of magma unfolded beneath this Atlantic island, but almost nobody realized it at the time.

Abstract In the Middle East, because of existence of fault lines, arid landscapes, and seismic activity, the geopathic stress (GS) could theoretically be amplified by natural formations. So, the architecture, environmental health, and bioelectromagnetics are most considered the challenges in geopathic stress in the mentioned countries. The main goal of this research is to build a framework that i…

Abstract UNESCO Global Geoparks function as outdoor learning environments that integrate science education with natural and cultural heritage. This study comparatively examines the educational strategies of selected geoparks in Türkiye (Kula–Salihli, Ida Madra) and Europe (Lesvos, Burren & Cliffs of Moher) in terms of pedagogical approaches, technology use, and learner roles. Using a qualitat…

Abstract Chlorine is a key volatile in magmatic and volcanic systems, being a major consumer of atmospheric ozone and an important ligand for metal transport. Despite chlorine’s importance however, the combined effects of melt composition and H₂O on Cl solubility and HCl degassing remain poorly constrained, particularly at magmatic pressures. We present high-pressure (0.5–1.63 GPa), 1200 °C exper…

Satellite imagery shows a surge of new volcanic activity in the ocean near Papua New Guinea. The post New Eruption in the Bismarck Sea appeared first on NASA Science .

Abstract The ~ 115 km long Sultandağı Fault forms the southern boundary of the Quaternary Afyon–Akşehir Graben in western Türkiye and represents a major active normal fault within the regional extensional regime. The Mw 6.5 Çay earthquake of 3 February 2002 produced surface rupture along its central segment, confirming its seismogenic capacity. This study presents the first detailed paleoseismolo…

Abstract The ratio of P-wave to S-wave velocity (Vp/Vs) is a key indicator of subsurface fluid pressure and rock properties. However, its spatial distribution in offshore regions has been poorly constrained because of difficulties in resolving shallow seismic velocity structures, particularly Vs structures. Recent advances in distributed acoustic sensing (DAS) enable dense seismic observations ev…

Computational mineralogy is fast becoming the most effective and quantitatively accurate method for successfully determining structures, properties and processes at the extreme pressure and temperature conditions that exist within the Earth's deep interior. It is now possible to simulate complex mineral phases using a variety of theoretical computational techniques that probe the microscopic natu…

Abstract The Martins-Portalegre Plateau, located in the semiarid region of the state of Rio Grande do Norte, Brazil, harbors a hydrological heritage of significant regional importance. However, the lack of (re)cognition by both local populations and public administrators has contributed to the degradation of its Sites of Hydrological Interest (SHI). This study aims to classify twelve (12) Hydrolo…

Campi Flegrei, a volcanic caldera near Naples, is speeding toward a transition, a new study suggests, but there are still a lot of questions as to whether it will erupt in the near future.

Scientists have uncovered how a huge underground magma surge shook Portugal’s São Jorge Island with thousands of earthquakes. In March 2022, São Jorge Island in Portugal’s Azores experienced thousands of earthquakes caused by a huge underground surge of magma (molten rock), according to a new study led by researchers at UCL (University College London). The [...]

Abstract We develop a mathematical framework for analyzing inter-regional earthquake triggering using multi-lag transfer entropy. While transfer entropy itself is well-established in information theory, its systematic application to discriminate earthquake triggering mechanisms across tectonic regions has not been previously formalized. We introduce the Multi-Lag Significance Profile (MLSP) as a …

Abstract Lower Cretaceous strata of the Eastern Cordillera of Colombia host some of the world’s premier emerald deposits, yet the timing of mineralization—and its relationship to the tectonic evolution of the Cordillera—remains poorly constrained. We present high-resolution in situ U–Th–Pb petrochronology of monazite and xenotime from both the Eastern and Western Emerald Belts, revealing at least…
