Determining the Character of Subglacial Sediments in the Ice‐Bedrock Interface Zone of Antarctica Using Horizontal‐to‐Vertical Spectral Ratios (HVSRs) of Seismic Ambient Noise

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Interactions between the Antarctic Ice Sheet and the underlying solid Earth occur within the ice‐bedrock interface zone (IBIZ), containing structures of sediments and rocks that strongly influence ice sheet dynamics. Existing insights into the Antarctic IBIZ come primarily from interpretations of airborne geophysical data and active seismic ...

Reactivation Mechanism of Dormant Earthflows: Insights From the San Benedetto Landslide (Northern Apennines, Italy)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

Analysis of microtremor records

Bulletin of the New Zealand Society for Earthquake Engineering, 1973
A previous paper 
described two techniques developed at the University of Auckland, School
of Engineering for recording microtremors. In this paper, various possible methods of analysing such records, with emphasis on the discernment
 of frequency content, are outlined.

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...
