Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions. However, these processes do not always produce surface manifestations and may sometimes elude detection by current geological and geodetic monitoring.

Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within the accretionary wedge. The mechanics of these shallow rupture phenomena and their dependence

A New Classification of In Situ and Anvil Cirrus Clouds Uncovers Their Properties and Interhemispheric Connections

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract The challenge of distinguishing convective anvil cirrus from in situ cirrus has long limited the quantification of their distinct roles in regulating upper‐tropospheric moisture and modulating Earth's energy budget. In this study, we address this ambiguity by introducing a physically constrained classification framework that applies advanced ...

Degenerate Neutron Capture Rates in the Threshold of Neutron Star–Black Hole Mergers

The Astrophysical Journal
We first show that the rate of energy generation due to neutron capture rates can be important in neutron star–black hole mergers (NS–BH mergers) by considering neutron degeneracy.

Distinct Favored Regions for Historical Record‐Setting and Future Record‐Breaking Humid Heat

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Recent studies have revealed strong trends in humid heat, including the nearing of human physiological limits in some regions. Understanding of past extremes and their meaningfulness for contextualizing future possibilities, especially in the near‐term, is limited by the absence of a global analysis focused on the most extreme humid‐heat ...

Why Hydrological Memory Dominates in Low‐Latitude Highlands: A Mechanistic Shift in Ecosystem Response to Extremes

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Understanding how compound extremes affect terrestrial ecosystems is a major challenge in Earth system science. Although the combined effects of stressors are recognized, the manner in which the prestress state determines the basic response mechanism remains unclear.

Entropy in Hydrology

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...
