Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

The Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Discussion of “Spatio‐Temporal Modeling of Extreme Induced Seismicity in the Presence of an Evolving Measurement Network”

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT This discussion focuses on unique two aspects of the study: The use of the generalized pareto distribution to extrapolate below a threshold and the tension that exists between extreme value methods and the desire to provide an upper bound.

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.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2855-2879, September 2026.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.
