Relative Source Time Functions, Spectral Ratios, and Near‐Source Spallation in the Source Physics Experiment Phase I Chemical Explosions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The Source Physics Experiment (SPE) Phase I was composed of six chemical explosions at the Nevada National Security Sites (NNSS) between 2011 and 2016. The experiment provided a robust set of dense, local to regional distance observations suitable for characterizing shallow chemical explosions located within the same borehole.

Grain‐Scale Heterogeneity in Fault Veins Influences Shear Rupture, Damage Distribution, and Microseismicity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Fault veins, mineral‐filled fractures within fault zones, exhibit substantial grain‐scale structural variation, yet, the mechanical consequences of this heterogeneity on fault deformation and seismicity remain poorly constrained. Here, we use the Discrete Element Method to investigate how grain‐scale heterogeneity in quartz veins, which are ...

The deterministic behaviour of earthquake rupture beginning

Communications Earth & Environment
Earthquakes are among the most destructive natural hazards whose released energy can be quantified by their magnitude. Predicting how much energy will be released before the end of the rupture process represents a challenging question. The way earthquake

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Reconsideration of the energy balance in earthquake faulting

Progress in Earth and Planetary Science
The occurrence of earthquakes is now understood as brittle shear fracture releasing the elastic potential energy stored in the earth. Since the 1950s, many studies on the energy balance in earthquake faulting have been done, but there seems to be some ...

Ecological Processes Underpinning Microbial Variability in Archean Granitoids Beneath the Deccan Traps: Evidence From Deep Drilling in Koyna, India

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Deep biosphere hosted by Archean granitoid basement of Deccan Traps showed depth‐wise microbial partitioning. Limited dispersion and variable selection control community assembly. Fewer abundant bacterial taxa were ubiquitous, while large numbers of rare taxa remained localized.

Distribution of Radiation in Erbil city

Diyala Journal of Medicine, 2019
Background: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes electro-magnetic radiation such as radio waves, visible light, and x-rays, particle radiation ...

Discrete radiation sources of the 2024 Noto Peninsula earthquake: linking teleseismic pulses and near-field observations

Earth, Planets and Space
Understanding the rupture process of large earthquakes is critical; however, standard rupture process inversions require stabilizing constraints, which can obscure which features are genuinely required by the data.
