An improved seismicity picture of the Southern Tyrrhenian area by the use of OBS and land-based networks: the TYDE experiment

The problem of large location uncertainties for seismicity occurring in the Southern Tyrrhenian Sea have been partially exceeded during the implementation of the long-term scientific mission of the TYrrhenian Deep sea Experiment (TYDE), which allowed the installation of 14 wide-band Ocean Bottom Seismometers (OBS) and Hydrophones (OBH) in the period December 2000 – May 2001 on the sea-bottom floor around the Aeolian and Ustica Islands. Local events recorded at landstations have been observed also on the seismograms of the Ocean Bottom Seismic Network (OBSN). Moreover, some hundreds of low magnitude events, undetected from the land networks, have been recorded. We combined the readings of body wave arrival times from OBS-OBH with those from landstations to localise seismic events. We focused our study on three clusters of events representative of the seismic activity of the area: (i) "deep" events, (ii) Ustica (iii) NE-Sicily. The analysis of the integrated data set of the seismicity off-shore and on-shore, obtained from the combined land-OBS seismic network (Ustica sequence and Deep events), has improved locations in terms of RMS residuals, azimuthal gap, epicentral and hypocentral errors. Moreover, further classes of events have been analysed: the first one includes some local events that could be located only by integrating single trigger readings from the few available land-stations with the OBSN-data; the second one comprises local events that have been detected only by the OBS-OBH stations. In particular, the last cluster underlines the importance of an OBSN in the Tyrrhenian deep basin to reveal its unknown intense micro-seismicity, permitting to better understand both the tectonic and geodynamic picture of the area

"Dynamic Mediterranean”: an educational path through Earth science and geophysical research at Genova Science Festival 2010

Science Festivals are events world wide organized, and they have became more and more one of the most effective playground where science meet people. Genova Science Festival, held since 2003, is the Italian most interesting event of that type. The Istituto Nazionale di Geofisica e Vulcanologia (INGV), one of the largest European scientific institution deal- ing with Earth Sciences research and real-time surveillance, early warning, and forecast activities in geophysics and volcanology, participates every year developing a specific educational path, concerning some of its research areas. For the 2010 Genova Science Festival, the INGV has produced an educational exhibition called “Mediterraneo Dinamico” (Dynamic Mediterranean). This is a journey in the geodynamical history of the Mediterranean region from 200 million years ago till present. This long process took place also through some instantaneous dramatic events as eruptions, tsunami, earthquakes, whose studies have revealed their strong impact on cultural Mediterranean evolution as well as on environmental aspects as climate. The exhibition path aim is to illustrate and explain to general public, and especially to teachers and students, the results from researches conducted by INGV also in collaboration with other Italian and International partners, as well as from the real time Mediterranean sea water monitoring. The chosen exhibition instruments are wide colourful illustrated posters, greatly illustrated, together with smart interactive exhibits. In particular the path starts with a “Time Machine”, that allows visitors to retrace the main steps of the Mediterranean geological evolution, supported by posters. The following section concerning the “Mediterranean catastrophic event” welcome visitors with a glass pyramid projecting a virtual eruption almost as an “ologramma”, and side panels with two short videos explaining two great explosive eruptions and a tsunami event. The section on Mediterranean Tsunami are equipped with an interactive large map of the location of Mediteranean where occurred tsunami events, illustrated posters and also a microscope with a camera where visitors can analyse a core with a tsunami deposits. Also an interactive model of a GEOSTAR - Geophisical and Oceanographic Station of Abyssal Research provide visitors an entertaining approach on how a submarine observatory works with all his sensors, while a computer station permits visitors to read real time measures of some marine environmental indicators. The exhibition journey trough the Mediterranean geo-history and Earth Science and Geophysical research shows how the continuous knowledge and monitoring of to this Region dynamics are fundamental to design a future bearable development for the 30 million people living along the Mediterranean shores

A first insight into the Marsili volcanic seamount (Tyrrhenian Sea, Italy): results from ORION-GEOSTAR3 experiment

The Marsili Seamount is the largest European underwater volcano. It is Plio-Pleistocenic in age, rising up to more than 3000m from the seafloor in the SE Tyrrhenian basin (Central Mediterranean), a back arc basin which began progressively opening 10 Ma ago (Kastens et al., 1988). The seamount lies in a key area for understanding the evolution of the Tyrrhenian region, characterized by high values of heat flow (Della Vedova et al., 2001) and low values of Moho isobaths (Locardi and Nicolich, 1988). In spite of the large dimensions of the Marsili seamount, we still have limited knowledge of its present activity. Ocean exploration is dependent on available technology and infrastructure, which started to develop strongly only after the 1980s. In fact, from its discovery in the 1920s, very little was known of the Marsili Seamount until the late 1990s when new techniques such as multibeam acoustic bathymetry were developed allowed to reveal at least the morphology. Some dedicated expeditions then obtained the first morpho-bathimetric map of the entire Tyrrhenian seafloor, based on multibeam swath-mapping together with seismic, gravimetric and magnetometric data (e.g. Marani and Gamberi, 2004). Although these data have greatly contributed to our understanding, the necessarily short measurement time limits the extent to which they reflect short- to medium-term geophysical processes in the Tyrrhenian basin. New technologies, such as multiparameter seafloor observatories, provide long-term continuous time-series in deep ocean waters, which are the basis for an original approach in ocean exploration. The observation of phenomena variability over time is key to understanding many Earth processes, among which we recall hydrothermal activity, active tectonics, and ecosystem life cycles. The development in Europe of multidisciplinary seafloor observatories has been pioneered under the EC Framework Programmes, specifically in the GEOSTAR projects (Beranzoli et al., 1988, 2000). From 2003 to 2005, long-term geophysical and oceanographic monitoring was conducted within the EC ORION-GEOSTAR3 project with two multiparameter observatories deployed on the seafloor 3320m below sea level (b.s.l.) in the vicinity of the Marsili Seamount. The two observatories were equipped with a set of sensors providing long-term continuous time-series of various physical measurements. The acquired time series are the longest continuous data record of the Marsili Basin available so far. This chaper intends to provide the main information on this experiment and present some results of the processing of the corresponding time-series, adding new valuable information on the still poorly explored activity of the volcano seamount. This chapter is organized as follows: The next section will provide the geological setting to understanding the importance of the Marsili Seamount and its basin; the ORION-GEOSTAR3 experiment is described in Section 24.3; some results from this unprecedented seismic, magnetic and gravimetric data analyses are shown in Section 24.4; and finally, in the last section we present our discussion with the main conclusions.Published623-6413A.

NEMO-SN1 Abyssal Cabled Observatory in the Western Ionian Sea

The NEutrinoMediterranean Observatory—Submarine Network 1 (NEMO-SN1) seafloor observatory is located in the central Mediterranean Sea, Western Ionian Sea, off Eastern Sicily (Southern Italy) at 2100-m water depth, 25 km from the harbor of the city of Catania. It is a prototype of a cabled deep-sea multiparameter observatory and the first one operating with real-time data transmission in Europe since 2005. NEMO-SN1 is also the first-established node of the European Multidisciplinary Seafloor Observatory (EMSO), one of the incoming European large-scale research infrastructures included in the Roadmap of the European Strategy Forum on Research Infrastructures (ESFRI) since 2006. EMSO will specifically address long-term monitoring of environmental processes related to marine ecosystems, marine mammals, climate change, and geohazards

Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population
