Master degree fieldwork: The electric response of clay’s deposits in the geothermal area of Saturnia (Italy, Grosseto)

The activity done in this fieldwork aimed to execute a geo-electric tomographic survey (to calculate the resistivity values across the depths and along specific hangings) in the geothermal area of Saturnia (Figure 1). To be more specific, the focus of the study were on the clay’s deposits and then be able to extract from them… Continue reading Master degree fieldwork: The electric response of clay’s deposits in the geothermal area of Saturnia (Italy, Grosseto)

AGU + California road-trip

The aim of this travel was to partecipate to a conference in San Francisco (AGU). It is the biggest conference in geophysics wordwide. Me and other two friends decided to stay a bit longer to have the chance to travel a bit around. From San Francisco we headed to Sequoia Park followed by Yosemite park.… Continue reading AGU + California road-trip

Seismic Ambient Noise: Group/Phase velocity dispersions and maps (Part II)

The CC contains velocity dispersion information (group/phase velocity) about the medium traversed by surface waves (the ambient seismic noise is mainly constituted by surface waves, see the previous article)  between each station pair. Once the dispersion information is extracted, it is possible to apply seismic tomography to obtain corresponding group and phase velocity maps. For the… Continue reading Seismic Ambient Noise: Group/Phase velocity dispersions and maps (Part II)

Seismic Ambient Noise: Cross-correlations (Part I)

Cross correlations and Ambient Seismic Noise (ASN) The recorded ambient seismic noise is generated mainly by natural sources such as meteorological and oceanic disturbances. For example, sea waves are capable of producing a certain pressure that can then vertically propagate to the sea floor and generate ground motion. The vertical force will also generate Rayleigh… Continue reading Seismic Ambient Noise: Cross-correlations (Part I)
