Scalera (2008) using the data available in 2006 in the Smithsonian Institution Catalogue of the volcanic eruptions, has revealed evidence that earthquakes happened into the South-American Wadati-Benio zone – with magnitude greater than 8.4 –are associated to an enhanced rate of volcanic eruptions, but has been impossible to determine the causal chain between the two phenomena. After 2006, the effort of the Smithsonian Institution to improve our knowledge of this region has resulted in a greatly increased completeness of the catalogue, adding the new eruptions for the 2000- 2010 interval, but also an additional 50% of new entries in the list of the Andean volcanoes. The occurrence of the Chilean earthquake of Maule – 27 February 2010 (M=8.8); occurred at five decades from the 1960 quake – has been the occasion to rework all the data searching for additional clues able to indicate a preferred causal direction eruptions-earthquakes or earthquakes-eruptions – or from a third more general cause (e.g. a mantle movements) to both eruptions and earthquakes. This short note discusses the three above-said hypotheses and tries to establish if these results could be useful to the aims of the Civil Protection in the programs of prevention and/or forecasting of natural disasters.

Old critical arguments around the possibility of a vicious circle in the geodetic theoretical methods (Blinov, 1987; Scalera, 2003) has revealed their inadequacy in respect of the geometry of space geodesy. On the bases of an old argument (Scalera, 2003), it has been then developed a new more realistic one, in which it is demonstrated that spurious effects can probably bias what is believed to be systematic-error-free data. It is argued that Geodesy still has to full develop a theoretical treatment of an expanding globe Fri, 30 Nov 2012 23:00:00 GMT http://hdl.handle.net/2122/8657 2012-11-30T23:00:00Z http://hdl.handle.net/2122/8611 Title: Caractères morphologiques du mont Vésuve Authors: Ricciardi, G. P.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia Editors: Beck Saiello, E'.; Bertrand, D. Abstract: La morphologie du Vésuve a évolué au fil des éruptions et l’image de la fresque du Centenaire à Pompéi a cessé de le représenter avec exactitude après l’éruption de 79. Le volcan se compose en fait de deux édifices successifs : la Somma, cratère résiduel de l’ancien volcan, et le cône plus récent du Vésuve proprement dit. De 1631 à 1944, l’évolution morphologique est bien documentée, grâce aux nombreuses relations et représentations, ou aux relevés exécutés par Della Torre au xviiie siècle, par Schiavoni au xixe siècle. Le sommet en aura ainsi varié ainsi que son profil dont les modifications ont pu être enregistrées au cours de ces trois siècles d’intense activité volcanique.

A Continuous GPS network constituted by about 130 stations has been deployed all over Italy. The development and the realization of a stable GPS monumentation, the integration with other classical seismological instruments and the choice of both satellite and internet data transmission make this network one of the most innovative and reliable CGPS networks in the world. The development of the CGPS network has been accompanied by a technologically advanced development of all the aspects related to the data acquisition and the data information mining: a database and a SIT. Based on the recent techniques of Knowledge Management, the database has been developed to manage the data and the data information of all the sites of the RING network, thus allowing us to centralize information in a single common data bank and to create an unique service of access point to the data from different remote sites by internet connections. The SIT has been developed to be fully integrated with the Knowledge Management technology and it is aimed to synthesize and to display in a geographic interface the information of the RING sites. This work has been integrated with all other spatial data, such as topographic and geo-thematic maps, geological, seismological and seismo-tectonic databases. In this work, the technological aspects of the SIT of the RING network will be detailed and some examples of thematic maps will be shown.

Campi Flegrei caldera, placed west of Naples, is a well known example of peculiar ground deforàations (bradyseism), chanctenzed by period of intense uplift, nor necessarily culminating in an eruptive phase (the last eruption occurred in 1538), followed by a subsidence phase. Recently, during the 1970-1972 and 1,982-1984,t he caldera has been affected by two intense episode of intense uplift (sine eruption). In 1985 a subsidence phase started (with some episodic small and fast uplifts superimposed) and terminated at end of 2004. Somma-Vesuvio, at east of Naples, is a quiescent volcano (the last eruption occurred in 1944) and is charactenzed by a low level of ground deformatio.r, .*..p. small and limited subsidence are s, located near craLter area and around the volcanic edifice. Ischia island, at S\ù7 of Naples, has been characterrzed rn the past times by a both explosive and effusive volcanic activity (the last eruption occurred in 1302). Successively the ground deformation activity has been charactenzed by a meaningful subsidence in the S and NW sectors of the island. Ground deformation is usualy ónnected with pressure changes of magma reservoirs or with intrusive events. So, monitoring and analysis of ground deformations are important tools in order to understanding the geometry, dynamics and evolution of thr source. The NeVoCGPS QNeapolitan Volcanic Continuous GPS) network consists of 25 stations (Fig. 1), managed by remote control. The data are automatically downloaded and proceised daily by the Ultra rapid IGS products. \ù7hen the IGS final orbits and Earth rotation parameters (trRPt become avallable the data are reprocessed and weekly solutionr àr. obtained, also. The data processing is performed by the Bernese Processing Engine (BPE) of the Bernese GPS software v. 5.0 in double difference mode. The èlevaiion cut-off is set at 1'5o and the IGS absolute phase centre variations (APCVO for the satellite and receiver antennas are applied. To minimize the tectonic movements contribution, the GPS position time series are estimated relative to the stable station ENAV located outside the volcanTc area. The NeVoCGPS datahave been always very useful for ground deformadon study, pointing out also small intensity phenome na, that usually are not discriminated by discontinuous measures.
