Chebyshev array forming for near surface investigations
No full textIn recent years, reflection seismics has increasingly been extended to near surface investigations to help in better delineate the subsurface properties, in particular the shallow layers geometry. The applications of shallow reflection surveys range from hydrogeological prospecting (Pugin et al., 2009; Ge et al., 2010), environmental and engineering problems (Miller and Steeples, 1994; Shtivelman, 2003), landslide characterization (Malemhir et al., 2013; Stucchi et al., in press) to mention but just a few.
The generally limited availability of recording hardware when compared to oil or mining exploration, and the often poor performance of the energy sources, are two problems that add to the known difficulties inherent to the near surface exploration (Steeples and Miller, 1998). It is quite common to employ recording equipment using only 24 or 48 active channels, with single vertical or horizontal geophone (for P- or S-wave survey), and simple energy sources such as the sledgehammer or the weight drop. This results in a poor depth penetration of the seismic signal and in a severe source related noise contamination (ground roll and air blast) of the acquired data. However, it may be possible to turn these hardware weaknesses into potential advantages. In fact, the relative facility of striking blows with the sledgehammer and the flexibility aptitude of 24-48 channel short spreads allow the geophysicist to acquire a plentiful quantity of data and to leave to the processing lab the task to appropriately stack them to increase the signal-to-noise (S/N) ratio. This corresponds to performing source and/or receiver array simulations, where the output can be optimized on the basis of specific criteria such as noise attenuation or resolution. Indeed, contrarily to what happens in the field where the arrays would be fixed along the entire profile, the simulation of arrays in the processing can be time and space variant and their responses can be changed according to the changing characteristics of the data.
In our work we demonstrate how effective spatial filters can be easily obtained by properly mixing and weighting different traces and how this turns out in a fair improvement in the data quality. The optimal weights are computed by means of Chebyshev polynomials (Carlini and Mazzotti, 1989; Holzman, 1963), where “optimal” is intended as more efficient and uniform noise attenuation in the array filter stop-band region compared to the un-weighted array. The real data pertain to a reflection survey carried out to delineate the subsurface structure of a huge landslide located in the Northern Apennine, Italy (Stucchi et al., in press). A 10 kg sledgehammer and a 48 channels single geophone spread were used as the energy source and the recording devices in the production phase
SH-wave reflection seismic survey at the Patigno landslide: integration with a previously acquired P-wave seismic profile
No full textSeismic investigation on landslide is hampered by several factors that could
prevent the use of the reflection seismic method to characterize the subsurface architecture
(Jongmans and Garambois, 2007). Moreover, acquisition and processing of reflection seismic data
are more time consuming compared with other geophysical techniques such as refraction seismic
and electrical resistivity tomography (ERT), leading inevitably to higher costs. Notwithstanding
these difficulties, recently some attempts to delineate the deep slip surface of large landslides have
been carried out using P-wave reflection seismic surveys (Apuani et al., 2012; Stucchi and
Mazzotti, 2009; Stucchi et al., 2014;). P-wave reflection seismic method is effective in imaging the
slip surface at a depth sufficiently greater than the seismic wavelength, whereas, for very shallow
horizons, it suffers from the limited resolution that can be obtained by the use of compressional
waves. In this regards, SH-waves can be used to overcome this limitation (Deidda and Balia, 2001;
Guy, 2006; Pugin et al., 2006,), but they require a specifically-designed energy source for waves
generation, geophones measuring horizontal components of particles motion and an accurate choice
of acquisition parameters. On the contrary, due to attenuation, the depth of investigation for SHwaves
can be lower than for P-waves (Pugin et al., 2006). Therefore the geological understanding of
a mass movement can take advantage of a combined use of both these geophysical methodologies.
This is the case of the Patigno landslide, a great landslide located in the upper basin of Magra River,
in the Northern Appennines, Italy (Fig.1), where a P-wave study carried out in the last years
(Stucchi et al., 2014) was able to image the deepest discontinuity of the landslide body at around
40-50 m depth, but no description of the shallower layers can be inferred. Because these surface
layers are the slip surfaces of quick reactivation movements of the landslide, an SH high-resolution
reflection seismic survey was planned along the previous P-wave profile (Fig.1). This new survey
associated to the P-wave investigation allows a more robust description of the landslide body, from
the deepest discontinuity up to the very shallow portions of the landslide.
This work describes the planning, acquisition and processing of the SH reflection seismic survey,
and also gives a possible combined interpretation of both P and SH seismic images

I VERSI DEL SATYRICON
No full textIl volume rappresenta la prima edizione completa, in lingua italiana, successiva alla monografia in lingua inglese a cura di A. Setaioli (Peter Lang, 2011), che presenti la traduzione completa con breve commento di tutti i versi intarsiati nella prosa del "Satyricon". Le traduzioni, di Luca Canali, sono precedute da una introduzione scritta a quattro mani dai due autori, mentre S. Stucchi è autrice delle contestualizzazioni e delle note di commento ai singoli inserti poetici in relazione ai problemi testuali che essi presentano e ai loro legami tematici con la cornice costituita dal "Satyricon"
Autobiografia immaginaria, riscrittura, reinvenzione: tre sentieri per la ricezione di Petronio
No full textIl breve saggio di Silvia Stucchi si propone di analizzare la ricezione di Petronio negli ultimi vent'anni, prendendo a modello tre opere di genere romanzesco che attestano tre diverse modalità di relazionarsi con il "Satyricon": Luca Canali con "Satyricon- Se Petronio l'avesse scritto oggi" (1997) si pone nel solco di una abbastanza tradizionale riscrittura, aggiornata ai tempi contemporanei; Jesse Browner, con "The Uncertain Hour" (2007, tradotto in italiano come "L'ora incerta- L'ultima cena di Petronio", 2009), pur non essendo un latinista o un antichista, rielabora le suggestioni dell'opera petroniana e le notizie sulla vita del suo autore sino ad offrirci una autobiografia immaginaria. Infine, G. M. Villalta, poeta e romanziere, con "Satyricon 2.0" (2014), costruisce, seguendo molto liberamente il canovaccio rappresentato dal modello latino, un apologo sulla condizione del giovane intellettuale nell'Italia di inizio XXI secolo
