Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls

open access: yesJournal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022
Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

Diverse Deformation Mechanisms and Lithologic Controls in an Active Orogenic Wedge: Structural Geology and Thermochronometry of the Eastern Greater Caucasus

open access: yesTectonics, Volume 41, Issue 12, December 2022., 2022
Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Universal Graphs at $\aleph_{ω_1+1}$ and Set-theoretic Geology [PDF]

open access: yesarXiv, 2016
This thesis consists of two parts: the construction of a jointly universal family of graphs, and then an exploration of set-theoretic geology. Firstly we shall construct a model in which $2^{\aleph_{\omega_1}}=2^{\aleph_{\omega_1+1}}=\aleph_{\omega_1+3}$ but there is a jointly universal family of size $\aleph_{\omega_1+2}$ of graphs on $\aleph_ ...

A Deeper Look Into the 2021 Tyrnavos Earthquake Sequence (TES) Reveals Coseismic Breaching of an Unrecognized Large‐Scale Fault Relay Zone in Continental Greece

open access: yesTectonics, Volume 41, Issue 12, December 2022., 2022
Abstract Large magnitude (Mw ∼ ≥6) earthquakes in extensional settings are often associated with simultaneous rupture of multiple normal faults as a result of static and/or dynamic stress transfer. Here, we report details of the coseismic breaching of a previously unrecognized large‐scale fault relay zone in central Greece, through three successive ...

Evaluation of initial geostress field of underground powerhouse in the complex alteration area of western Sichuan based on back-propagation neural network method

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Rock alteration leads to the degradation of the physical and mechanical properties of original rock. The spatial variance in the degree of rock alteration significantly influences regional ground stress distribution characteristics.

Long‐term hydrologic connectivity on the Australian dryland margins: Evidence from the Willandra Lakes World Heritage Area over the last 60 ky

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The semi‐arid Australian continental inland is increasingly subject to climatic extremes such as drought and flooding. Combined with the exceptionally low topographic relief characteristic of this region, hydroclimatic extremes can have an enormous impact on the land surface.
