Signatures of criticality in turning avalanches of schooling fish

Physical Review Research
Moving animal groups transmit information through propagating waves or behavioral cascades, exhibiting characteristics akin to systems near a critical point from statistical physics. Using data from freely swimming schooling fish in an experimental tank,

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Signal extraction and knowledge discovery based on statistical modeling

, 2006
In the coming post IT era, the problems of signal extraction and knowledge discovery from huge data sets will become very important. For these problems, the use of good model is crucial and thus the statistical modeling will play an important role.

A New Strategy for Improving Multi‐Frequency PPP‐RTK Ionospheric Correction Availability and User Performance in Low‐ and Middle‐Latitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract High‐precision regional ionospheric correction products are essential for achieving accurate and fast‐convergence solutions in Precise Point Positioning Real‐Time Kinematic (PPP‐RTK). For users in low‐ and middle‐latitudes, PPP‐RTK server narrow‐lane (NL) ambiguity resolution (AR) typically requires more than 10 min, which largely affects the ...

Bayesian earthquake forecasting approach based on the epidemic type aftershock sequence model

Earth, Planets and Space
The epidemic type aftershock sequence (ETAS) model is used as a baseline model both for earthquake clustering and earthquake prediction. In most forecast experiments, the ETAS parameters are estimated based on a short and local catalog, therefore the ...

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

Direct observations of causal links in plastic events validates statistical analysis tools for seismology

, 2022
Earthquakes are complex physical processes driven by the stick-slip motion of a sliding fault. After the main quake, a series of aftershocks typically follows.

Precise Temperature Measurements and Long‐Term Observations Revealed an Almost‐Constant Temperature Zone in a Vertical 700‐m‐Deep Borehole in the Aso Volcanic Region

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract To determine the subsurface temperature distribution and its relevance to groundwater flow in the deep subsurface, we repeated temperature depth profile measurements and conducted long‐term temperature observations in an ∼700‐m‐deep borehole penetrating the Futagawa fault along the Kiyama–Kashima graben in the Aso volcanic region, Japan from ...

Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...
