Seismological Evidence of Multiple Crustal Magma Reservoirs Beneath Mt. Wrangell in Southcentral Alaska

Geophysical Research Letters
Recent studies have challenged the classical view of magma chambers as ephemeral, melt‐rich bodies confined to shallow depths beneath arc volcanoes at subduction zones.

Quantifying Microstructural Evolution in Moving Magma

Frontiers in Earth Science, 2020
Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate.

Feeding of a magma chamber by an ascending magma bubble

Geophysical Journal International, 2021
SUMMARY There is evidence that magma chambers are not fed by a continuous flow, but in the form of discrete magma batches. The possibility is considered that the chamber is fed by a magma bubble ascending through the region underneath, driven by buoyancy force.

Examining the multivariate genetic architectures of posttraumatic stress disorder and cardiovascular disease phenotypes

Journal of Traumatic Stress, EarlyView.
Abstract Posttraumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, but the extent of shared inherited liability is unclear. Large genome‐wide association studies (GWAS) allow for multivariate evaluation of common genetic architecture.

The magma thermal field and the shallow-level gas accumulation of tight gas reservoirs in the middle-eastern parts of the Qinshui Basin

Earth Sciences Research Journal, 2019
In this study, the metal-non-metal mineral gas-water hydrothermal concept is used to analyze the movement channels of magmatic heating water. Further, the concept of fractures-faults-cracks microfissures hierarchical configuration of the movement ...

Ductility and Compressibility Accommodate High Magma Flux Beneath a Silicic Continental Rift Caldera: Insights From Corbetti Caldera (Ethiopia)

Geochemistry, Geophysics, Geosystems, 2020
Large silicic magma reservoirs preferentially form in the upper crust of extensional continental environments. However, our quantitative understanding of the link between mantle magmatism, silicic reservoirs, and surface deformation during rifting is ...

Unexpected Primes of Good Reduction in Quotients of Modular and Shimura Curves

Mathematische Nachrichten, EarlyView.
ABSTRACT We find all zero‐dimensional spaces of newforms of weight 2 and squarefree level N$N$ with a fixed Atkin–Lehner sign pattern. As an application, we classify unexpected primes of good reduction of Atkin–Lehner quotients of modular and Shimura curves of squarefree levels.
