No full textIn order to discriminate normal (i.e. related to the change of natural factor and/or observation conditions) fluctuations of Earth’s emitted Thermal Infrared (TIR) radiation from anomalous transients possibly associated to earthquake occurrence, since 2001 a Robust Satellite Technique (RST; Tramutoli, 1998; 2005; 2007) approach has been applied. After the first tests performed by using TIR sensors on board polar satellites it was quite evident the advantage offered by the use of geostationary platforms in studies like these, which do not require the higher spatial resolution offered by polar sensors but strongly benefit of the reduced “observational noise” (in terms of view angles, ground resolution cells stability and image collection times) guaranteed by geostationary platforms (e.g. Filizzola et al., 2004). Since then, tens of earthquakes occurred in Europe, Asia, Africa and America have been studied by analyzing long terms (up to 10 years and more) time series of TIR images acquired by geostationary satellites (like MFG, MSG, GOES, MTSAT). In all cases a validation/confutation approach was always applied in order to verify the presence/absence of anomalous space-time TIR transients in presence/absence of significant seismic activity. Main achievements in more than 10 years using RST approach for seismic area monitoring will be presented and discussed by comparing results obtained on different earthquakes which happened in different geographic areas and using different satellite sensors
New stratigraphic and structural evidence for Late Pleistocene surface faulting along the Monte Olimpino Backthrust (Lombardia, N Italy)
No full textWe summarize some preliminary results achieved during the investigations conducted for the CARG Project, geological sheet n. 75 “Como”, i.e. the analysis of the Quaternary evolution of the “Monte Olimpino Backthrust” and the evaluation of its seismogenic activity. Cross-border field mapping between Ticino (CH) and Lombardia (IT) resulted in the finding of new outcrops (Borgo Vico site, in the north-western sector of the urban area of Como) located along the front of the Monte Olimpino Backthrust, that allowed to recognize evidence for Late Pleistocene reverse surface faulting along this structure.
At Borgo Vico, a clastic Tertiary unit, the Villa Olmo Conglomerate, intercalated in the Chiasso Fm. of Early Oligocene age, is thrust over a Late Pleistocene fluvioglacial and glacio-lacustrine sequence (Comerci et alii, 2007).
Until now, the Monte Olimpino Backthrust was supposed by most authors to have been active until Tortonian times. Sileo et alii (2007) inferred a Pliocene activity and proposed, based on geomorphic evidence, that fault displacement was still taking place during Pleistocene. However, this is the first time that Pleistocene activity along the Monte Olimpino Backthrust has been documented by unequivocal tectonic offset of late Pleistocene deposits. Paleoseismological analyses are in progress in order to distinguish potential coseismic movement from fault creep during the observed recent displacement
