Rayleigh-wave attenuation across the conterminous United States in the microseism frequency band
Autor: Fabrizio Magrini, Lapo Boschi, Lucia Gualtieri, Vedran Lekić, Fabio Cammarano
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-9 (2021)
Abstract Mapping variations in the attenuation of seismic energy is important for understanding dissipative mechanisms in the lithosphere, and for modeling ground shaking associated with earthquakes. We cross-correlate ambient seismic signal recorded

Multi-phase seismic source imprint of tropical cyclones
Autor: Lise Retailleau, Lucia Gualtieri
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-8 (2021)
The authors locate the maximum seismic energy imprint and lateral extent of the seismic sources generated by Typhoon Ioke. Based on this data set, they present a new tool to shed light on the generation mechanism of secondary microseisms body waves.

Generation of secondary microseism Love waves: effects of bathymetry, 3-D structure and source seasonality
Autor: Frederik J. Simons, Lucia Gualtieri, Etienne Bachmann, Jeroen Tromp
Publikováno v: Geophysical Journal International. 226:192-219
SUMMARYSecondary microseisms are ubiquitous ambient noise vibrations due to ocean activity, dominating worldwide seismographic records at seismic periods between 3 and 10 s. Their origin is a heterogeneous distribution of pressure fluctuations along

Multi-phase seismic source imprint of tropical cyclones
Autor: Lucia Gualtieri, Lise Retailleau
Publikováno v: Nature Communications
Nature Communications, Nature Publishing Group, 2021, 12 (1), ⟨10.1038/s41467-021-22231-y⟩
Nature Communications, Vol 12, Iss 1, Pp 1-8 (2021)
The coupling between the ocean activity driven by winds and the solid Earth generates seismic signals recorded by seismometers worldwide. The 2–10 s period band, known as secondary microseism, represents the largest background seismic wavefield. Wh

International audience; Primary microseism is the less studied seismic background vibration of the Earth. Evidence points to sources caused by ocean gravity waves coupling with the seafloor topography. As a result, these sources should be in water de

The origin of secondary microseism Love waves
Autor: Jeroen Tromp, Etienne Bachmann, Lucia Gualtieri, Frederik J. Simons
Publikováno v: Proc Natl Acad Sci U S A
The interaction of ocean surface waves produces pressure fluctuations at the seafloor capable of generating seismic waves in the solid Earth. The accepted mechanism satisfactorily explains secondary microseisms of the Rayleigh type, but it does not j

The persistent signature of tropical cyclones in ambient seismic noise
Autor: Salvatore Pascale, Flavio Maria Emanuele Pons, Lucia Gualtieri, Suzana J. Camargo, Göran Ekström
Publikováno v: Earth and Planetary Science Letters. 484:287-294
The spectrum of ambient seismic noise shows strong signals associated with tropical cyclones, yet a detailed understanding of these signals and the relationship between them and the storms is currently lacking. Through the analysis of more than a dec
