Hazard assessment of seismic-collapsed loess landslides on the Loess Plateau as exemplified by the M6.2 earthquake in Jishishan County, China

Frontiers in Earth Science
The Loess Plateau is marked by intense neotectonic activity and frequent earthquakes. Its unique physico-mechanical properties, combined with the granular overhead pore structure of loess, render it prone to seismic landslides triggered by strong ...

Operational Modal Analysis for Seismic Protection of Structures

, 2008
This thesis focuses on output-only modal identification tests and on the opportunities they provide in the field of seismic protection of structures. The problem of a good measurement process, in order to obtain high quality data and reliable results ...

Evaluation of strengthening techniques of traditional masonry buildings: case study of a four-building aggregate

Increasing appraisal of the durability, conservation state, and changeable use and function of old buildings in urban centers relies a great deal on the structural safety evaluation of vertical load capacity and the ability to resist horizontal forces ...

Seismic Tomography with Irregular Meshes

, 2013
The current state of seismic tomography using irregular parameterizations is described. A review is given of previous work in the area covering local, regional and global seismic applications. The potential advantage of an irregular parameterization over

Hierarchical classification of snowmelt episodes in the Pyrenees using seismic data.

PLoS ONE, 2019
In recent years the analysis of the variations of seismic background signal recorded in temporal deployments of seismic stations near river channels has proved to be a useful tool to monitor river flow, even for modest discharges.

Crustal accretion at the Reykjanes Ridge, 61°–62°N

We report results of a seismic, gravity, and magnetic survey of the Reykjanes Ridge spreading center at 61°–62°N, about 600 km from the center of the Iceland mantle plume.

Seismic investigation of crustal accretion at the slow spreading Mid-Atlantic Ridge-The Reykjanes Ridge at 57 45'N [PDF]

, 1996
Studies of mid-ocean ridges have provided evidence of magma chambers beneath both fast and intermediate spreading ridges. However no such features have been observed to date beneath slow spreading ridges.

Crustal accretionary processes at mid-ocean ridges - Valu Fa Ridge, Lau Basin [PDF]

, 1998
The structure of oceanic crust is surprisingly uniform, which suggests that crustal accretionary processes at mid-ocean ridges must be broadly similar, despite their different spreading rates and seafloor morphologies.

Satellite Signatures of Pre-Seismic Atmospheric Anomalies of 6 February 2023 Türkiye Earthquakes

Atmosphere
Time series satellite data, coupled with available ground-based observations, enable geophysicists to survey earthquake precursors in areas of strong geotectonic activity.
