mitigation occurs at higher wind speeds. TMD shows a discrete efficiency
regarding earthquake-induced vibrations that have caused resonant tower oscilla-
tions. The difference between El Centro and Hachinohe earthquakes shows the
influence of earthquake parameters on the TMD efficiency. As the reference wind
turbine responds to Hachinohe Earthquake with resonant vibrations, TMD reaches
a much better result than during El Centro Earthquake.
