Rock mass characterization coupled with seismic noise measurements to analyze the unstable cliff slope of the Selmun Promontory (Malta) [PDF]

open access: yes, 2017
In the Mediterranean area, cliff slopes represent widespread high-risk landforms as they are highly frequented touristic places often interested by landslide processes.

Seismic response of the geologically complex alluvial valley at the "Europarco Business Park" (Rome - Italy) through instrumental records and numerical modelling [PDF]

open access: yes, 2016
The analysis of the local seismic response in the “Europarco Business Park”, a recently urbanized district of Rome (Italy) developed over the alluvial valley of the “Fosso di Vallerano” stream, is here presented.

Seismic attenuation from recordings of ambient noise [PDF]

open access: yesGeophysics, 2012
ABSTRACT We applied seismic interferometry to data from an ocean-bottom survey offshore Norway and found that ambient seismic noise can be used to constrain subsurface attenuation on a reservoir scale. By crosscorrelating only a few days of recordings by broadband ocean bottom seismometers, we were able to retrieve empirical Green’s ...

Quantifying the influence of sea ice on ocean microseism using observations from the Bering Sea, Alaska [PDF]

open access: yes, 2011
Microseism is potentially affected by all processes that alter ocean wave heights. Because strong sea ice prevents large ocean waves from forming, sea ice can therefore significantly affect microseism amplitudes.

Spatial and temporal influence of sea level on inland stress based on seismic velocity monitoring

open access: yesEarth, Planets and Space, 2022
Earth’s crust responds to perturbations from various environmental factors. To evaluate this response, seismic velocity changes offer an indirect diagnostic, especially where velocity can be monitored on an ongoing basis from ambient seismic noise ...

Towards the Monitoring of Underground Caves Using Geomatics and Geophysical Techniques: 3D Analyses and Seismic Response

open access: yesISPRS International Journal of Geo-Information, 2023
Analyses of climate change, due to its impact not only on the weather and the environment but also on human health and life, are one of the most important study activities made in recent years.

Societal Impact of COVID-19 Crisis on the Ambient Seismic Noise in Metropolitan France

open access: yesSeismica
The COVID-19 pandemic led to restrictions on human mobility worldwide. In France, numerous phases of lockdowns and curfews were instituted in an attempt to limit the consequences of this pandemic.

Toward Forecasting Volcanic Eruptions using Seismic Noise

open access: yes, 2007
During inter-eruption periods, magma pressurization yields subtle changes of the elastic properties of volcanic edifices. We use the reproducibility properties of the ambient seismic noise recorded on the Piton de la Fournaise volcano to measure relative

Signal to Noise Ratio estimation in passive correlation-based imaging [PDF]

open access: yes, 2013
We consider imaging with passive arrays of sensors using as illumination ambient noise sources. The first step for imaging under such circumstances is the computation of the cross correlations of the recorded signals, which have attracted a lot ...

WMSAN Python Package: From Oceanic Forcing to Synthetic Cross-correlations of Microseismic Noise

open access: yesSeismica
Seismic ambient noise spectra ubiquitously show two amplitude peaks corresponding to distinct oceanic wave interaction mechanisms called primary (seismic period (T) ~ 14 s) and secondary (T ~ 7 s) microseism.
