Bolide Light Curve Systematics from 75 Recovered Meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Politics and Justice: Aristotle, Rawls, and the Case for Realism in Political Theory

Philosophy &Public Affairs, EarlyView.
ABSTRACT Aristotle's analysis of stasis in Book V of the Politics offers a striking example of “distinctively political thought,” as advocated by Bernard Williams's political realism, and in contrast to the moralist approach exemplified by John Rawls. Aristotle identifies disputes over justice, driven by partial and conflicting conceptions of equality,

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Suite of Regional Seismic Velocity Models for the U.S. Atlantic and Gulf Coastal Plains (CPVMv2.0): Incorporating Epistemic Uncertainty in Velocity Models

Earthquake Spectra, Volume 42, Issue 4, November 2026.
The U.S. Atlantic and Gulf Coastal Plain (CP) sediments are kilometers‐thick, low‐velocity deposits underlain by high‐velocity bedrock that create regional patterns of amplification and attenuation of ground motions. Capturing these effects is challenging because of the limited subsurface information available, particularly the shear wave velocity (VS)

Deep Network Reparameterized Full‐Waveform Inversion From Sequential to Simultaneous Sources With Adjoint‐State Method

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Full‐waveform inversion (FWI) relies on sequential‐source (SQ) workflows for high imaging precision, while simultaneous‐source (SML) encoding drastically accelerates computation but introduces irreversible wavenumber discontinuity artifacts in hybrid‐domain implementations.

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Mapping the Crustal Thickness of the Andes Using pmP Phases Identified From Adaptive Teleseismic Array Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Crustal thickness (or Moho depth) is a key parameter for many geological and geophysical models. Despite this we have a limited number of measurements, typically from seismic receiver functions, to constrain variations in crustal thickness.
