Coupling Seismic, Gravity and Magnetic Surveys for the Investigation of Planetary Lava Tubes: A Terrestrial Analog Case Study in Lanzarote (Spain)

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

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 ...

Determination of Soil Properties by Using Multi-Channel Analysis Method Records of Microtremor, Earthquake and Surface Waves: A Sample Implementation from AFAD Campus

Doğal Afetler ve Çevre Dergisi, 2021
The most valid way to determine the soil amplification is to use the analysis of strong ground motion records. The Earthquake Observation Station located in Ankara AFAD campus was established in 2014.

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.

Preliminary seismic microzonation of Sivas city (Turkey) using microtremor and refraction microtremor (ReMi) measurements [PDF]

, 2013
Sivas city, located in the inner east part of Anatolia (Turkey), is far from seismic sources. However, the city is under risk owing to strong earthquakes occurring around the area, and different soil conditions that can produce variation in the ground ...

Effect of ground condition on microtremor characteristics in Miyazaki City [PDF]

, 2011
Observations were made of microtremors at 20 sites widely distributed in Miyazaki city to investigate the dynamic properties of surface soil layers. The microtremor measurements were carried out using a servo type pick.

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 ...

基于地脉动谱比的龙头山集镇局部场地特征分析

Dizhen xuebao, 2023
地脉动法已被广泛应用于场地特征分析，本文依据鲁甸龙头山集镇老行政机关办公区、老街区及骡马口村区三个震害严重区域的场地特征地脉动，并结合各区内建筑结构特点和局部场地效应分析了龙头山集镇场地特征对震害的影响，结果表明：各测试区具有显著的场地放大效应，且存在方向性差异；参考点谱比法与H/V谱比法虽有一定差异，但两方法的优势频带基本吻合；老行政机关办公区和老街区的建筑多为砖混结构，其震害较重是由其场地显著的放大效应及共振效应共同作用引起的；老街区与骡马口村区的土木与土石结构震害较重主要是由场地放大效应引起的。

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 ...
