Abstract
Abstract. Seismic signals produced by wind turbines can have an
adverse effect on seismological measurements up to distances of several
kilometres. Based on numerical simulations of the emitted seismic wave field,
we study the effectivity of seismic borehole installations as a way to
reduce the incoming noise. We analyse the signal amplitude as a function of
sensor depth and investigate effects of seismic velocities, damping
parameters and geological layering in the subsurface. Our numerical
approach is validated by real data from borehole installations affected by
wind turbines. We demonstrate that a seismic borehole installation with an
adequate depth can effectively reduce the impact of seismic noise from wind
turbines in comparison to surface installations. Therefore, placing the
seismometer at greater depth represents a potentially effective measure to
improve or retain the quality of the recordings at a seismic station.
However, the advantages of the borehole decrease significantly with
increasing signal wavelength.
期刊介绍:
Solid Earth (SE) is a not-for-profit journal that publishes multidisciplinary research on the composition, structure, dynamics of the Earth from the surface to the deep interior at all spatial and temporal scales. The journal invites contributions encompassing observational, experimental, and theoretical investigations in the form of short communications, research articles, method articles, review articles, and discussion and commentaries on all aspects of the solid Earth (for details see manuscript types). Being interdisciplinary in scope, SE covers the following disciplines:
geochemistry, mineralogy, petrology, volcanology;
geodesy and gravity;
geodynamics: numerical and analogue modeling of geoprocesses;
geoelectrics and electromagnetics;
geomagnetism;
geomorphology, morphotectonics, and paleoseismology;
rock physics;
seismics and seismology;
critical zone science (Earth''s permeable near-surface layer);
stratigraphy, sedimentology, and palaeontology;
rock deformation, structural geology, and tectonics.
