Two regional reflection seismic profiles were acquired to map the geometrical architecture of the Koillismaa Layered Igneous Complex (KLIC) in north-eastern Finland. Reflectivity up to a depth of ~5–6 km is delineated. The magma conduit associated with the KLIC was successfully revealed and the associated mineralization potential was established. A regional fault system associated with the magma emplacement was mapped for the first time.

We have studied the stress conditions at the Decatur CO₂ storage site that would induce the observed microseismicity. Initial estimates suggested that faults required higher pressure to slip than the injection pressure, but refining pressure and friction assumptions led to more realistic scenarios. Our study highlights the importance of accurate stress state measurements and high-quality data to better predict reservoir response to injection and improve the safety and reliability of CO₂ storage.

This study makes use of advanced seismic exploration techniques to look at the subsurface of South Africa's Kheis region. The results reveal hidden faults and folded rocks that help explain how ancient continents collided. The findings challenge older ideas about major geological boundaries and suggest a new model for how the crust formed and evolved. This work shows how old data, when re-analyzed with new methods and integrated with supporting data, can disclose important geological qualities.

We address the transition between the Paleozoic Variscan and Alpine Mesozoic–Cenozoic cycles using tectono-stratigraphy and thermochronology. This transition unfolds through a multi-phase rifting history. An initial rifting stage occurred in the early Permian, followed in the early–middle Permian by a phase of transcurrent tectonics. This was succeeded by a period of erosion/non-deposition in the middle Permian. Crustal stretching in the Middle Triassic marked the onset of the Alpine cycle.

We investigate women's representation in seismology to raise awareness of existing gender disparities. By analysing the authorship of peer-reviewed articles, we identify lower representation of women among single authors, high-impact authors, and highly productive authors. Seismology continues to be a male-dominated field, and trends suggest that parity is decades away. These gaps are an obstacle to women’s career advancement and, if neglected, may perpetuate the leaky-pipeline problem.

Infrequent eruptions of acidic magma are one of the most dangerous natural phenomena, but almost none of them have been witnessed by modern science. We present the first systematic characterization of seismicity recorded near an erupting acidic volcano (Cordón Caulle 2011). We define different phases of unrest and eruption, which combined with previous findings allows us to discuss the main processes associated with this type of violent eruption, with implications for their volcanic hazard.
