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 ...

Influence of Site Amplification Approaches in PSRA: Insights From Five Different Cities

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Regional and national seismic hazard models used in probabilistic seismic risk analysis often rely on generalized proxy‐based site terms to account for ground shaking amplification. This can result in coarse representations of site response, which can introduce bias or additional uncertainty in the associated risk results.

Seismic Structural Reliability by Time‐Variant Fragility Functions

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2669-2674, September 2026.
ABSTRACT The seismic vulnerability of aging structures is often represented in the form of fragility curves that vary with time. On one hand, each of these functions is intended to apply if the earthquake hits at the time the fragility refers to. On the other hand, performance‐based earthquake engineering (PBEE) resources to classical probabilistic ...

The Energy Space Density (ESD) Distribution: A New Approach to Reveal the Degree of Fracturing of the Crust in the Etna Region (Italy)

The Seismic Record
The traditional method of representing the seismicity in a region involves plotting earthquakes of various magnitudes on a map. Energy release, however, offers a different perspective for understanding seismicity, especially in volcanic areas where ...

Distribution of Partial Melt Beneath Changbaishan/Paektu Volcano, China/Democratic People's Republic of Korea

Geochemistry, Geophysics, Geosystems, 2020
Changbaishan/Paektu volcano straddles the border between the Democratic People's Republic of Korea and China. It was responsible for one of the largest eruptions in history, the “Millennium Eruption' of 946 CE. An episode of unrest between 2002 and 2005,

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Tectono‐Stratigraphic Evolution of a Shared Foreland Basin: A 3D Geomodel and Detrital Flux Reconstruction for the Pliocene‐Pleistocene of the Po‐Plain Basin (Northern Italy)

Basin Research, Volume 38, Issue 5, September‐October 2026.
The Plio‐Pleistocene succession of the Po Plain Basin was interpreted basin‐wide using seismic profiles and well data, identifying six major tectonic unconformities. Sediment volumes were calculated and decompacted to assess tectonic and climatic controls on basin infill, revealing a marked increase in detrital flux after 1.5 Ma, coincident with the ...

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

A deformation-driven earthquake interaction model for seismicity at Campi Flegrei

Communications Earth & Environment
Since 2005, the Campi Flegrei nested caldera volcano, located about 10 km west of Naples, Italy, has experienced accelerating uplift accompanied by increased seismicity, raising concerns in this densely populated area.
