GEOCHEMICAL AND GEOPHYSICAL RESEARCH AIMED AT CHARACTERIZING THE HYDRO-GEOLOGICAL STRUCTURES OF A KARST FORMATION

2009

Geochemical and geophysical research was effected in an area between the Madonia mountain range and the coast around the Rock of Cefalù, at the base of which there are a number of large-sized springs. The aim of the study was to reconstruct the buried hydro-geological structures that carry the waters from the Madonia Mountains to the areas along the coast where they surface. The Madonia Mountains are prevalently made up of carbonatic formations and terrigenous deposits of the Numidian Flysch. Outcrops of the Cozzo Terravecchia formation are also present, as are Messinian evaporitic deposits and recent detritic deposits of alluvial and marine origin. The Karst processes that develop in the l…

Indagini nell'area ad ovest del Tempio della Vittoria ad Himera

2021

Himera: New investigations in the area West of the Tempio della Vittoria · The University of Palermo has started a new cycle of field investigations in the “lower town” of Himera, with the aim of answering some questions about the relationships between the Tempio della Vittoria, the residential districts, and the agora, that remained to be clarified after the important results produced by the studies on the urban development of the Greek city over the past forty years. This paper presents some initial results and research perspectives from the first excavation soundings and geophysical survey of 2021. The first findings strongly suggest that the agora extended much further south than previo…

Geophysical study of the hydrothermal reservoir in the Panza area (Ischia, Italy)

2008

The aim of the work is the reconstruction of the main geometric pattern and the characterisation with geophysical parameters of geological structures lying at small and medium depths in an area of the Ischia island (Italy), where a sensible hydrothermal activity is present.

Integrated Geophysical Investigations at the Greek Kamarina Site (Southern Sicily, Italy)

2018

Kamarina, located in southern Sicily (Italy), was an important Greek colony since its foundation in the sixth century BC. Archaeological excavations, carried out since the twentieth century, uncovered only limited portions of the site so far. Despite the importance of the Greek colony, the presence of remarkable buildings that archaeologists expected to bring to light has not found fully correspondence in the archaeological excavations. Consequently, the integrated geophysical prospection carried out in the study area is aimed to support and address the future archaeological investigations. After the photographic and thermographic survey obtained by an unmanned aerial vehicle, we performed …

Modelling regional-scale attenuation across Italy and the Tyrrhenian Sea

2021

Abstract Modelling regional-scale attenuation of seismic waves at ~1 Hz is challenging, especially when these waves propagate across both continental and oceanic crust. Recent developments in seismic imaging and modelling have provided us with the computational tools necessary to reconstruct these mixed settings using deterministic (coherent) and stochastic (coda) information. Here, we present new tomographic maps of coda-attenuation for both the Italian peninsula and the Tyrrhenian Sea. Kernel-based coda attenuation imaging in the diffusive approximation is tested in the oceanic environment, highlighting a non-diffusive behaviour across the Southern Tyrrhenian Sea. Joint deterministic and …

A Low Cost Customizable Micro-ROV for Environmental Research - Applications, Advances and Challenges

2016

Summary Several shallow submarines areas are characterized by considerable releases of hydrocarbon gases, which, during earthquakes or volcanic activity, may suddenly and violently occur. In some instances, changes in chemical and physical properties of gas emissions, which are generated by geothermal systems connected to the volcanoes’ plumbing system, are important precursors of volcanic activity and useful indices for the study of the geothermal field. Furthermore, some superficial structures such faults, landslide slopes or archaeological relics should be studied with such a high detail that geophysical and bathymetric surveys are unable to provide. In response to the needs increasingly…

Geophysics and cultural heritage. A living field of research for Italian geophysicists

2015

If one reads the World Heritage List 2002/2003, (http:// whc.unesco.org/archive/WHList02-ENG.pdf), a datum comes out with evidence: 12 countries have 253 World Heritage Sites (WHS) and all the 125 member countries have 586 WHS. Within these 12 countries Italy has 35 WHS corresponding to about 6% of the whole, followed by Spain, 5.8%, France, 4.6%, and the tenth has less than 2% of WHS. Cultural heritage is one of the greatest riches of Italy. Europe, with China, is the land which has the most stratified history in the world, and Italy is likely to still have undiscovered settlements dating from the prehistoric age to the 18th century. Some areas are totally unexplored, others have been only…
