    Gas hazard assessment at the Monticchio Mt. Vulture, a volcano in Southern Italy (2009)
    Wiley-Blackwell
    Details
    Publication Date: 2017-04-04
    Description: Geochemical investigations have shown that there is a considerable inflow of gas into both crater lakes of Monticchio, Southern Italy. These lakes are located in two maars that formed 140 000 years ago during Mt. Vulture volcano s last eruptive activity. Isotopic analyses suggest that CO2 and helium are of magmatic origin; the latter displays 3He ⁄ 4He isotope ratios similar to those measured in olivines of the maar ejecta. In spite of the fact that the amount of dissolved gases in the water is less than that found in Lake Nyos (Cameroon), both the results obtained and the historical reports studied indicate that these crater lakes could be highly hazardous sites, even though they are located in a region currently considered inactive. This could be of special significance in very popular tourist areas such as the Monticchio lakes, which are visited by about 30 000 people throughout the summer, for the most part on Sundays.

    Seismology and Tectonic Setting of the 2002 Molise, Italy, Earthquake (2006)
    Earthquake Engineering Research Institute
    Details
    Publication Date: 2017-04-04
    Description: Two earthquakes (both having Mw 5.7) struck the eastern portion of Molise on October 31 and November 1, 2002. Both caused severe damage over a 2000 km2 region straddling Molise and Puglia. The two larger shocks and the rather unusual aftershock sequence surprised most Italian seismologists and tectonicists. Although Italy has a good record of historical and instrumental seismicity and its main seismogenic trends are quite established, the epicentral location, depth and kinematics of this earthquake sequence were largely unexpected. In fact, the 2002 Molise earthquakes shed light on a previously unsuspected style of seismogenic faulting in this region. From the seismotectonic perspective, much of the significance of the two quakes arises from the possibility that this style of faulting might be shared by several much larger quakes that took place on the Adriatic side of the southern Apennines. In the first part of this paper we briefly describe the main seismological characteristics of the sequence. These were largely derived from the analysis of data supplied by permanent networks and from a preliminary analysis of data recorded by a portable network deployed a few hours after the first shock. In the second part of the paper we discuss the seismotectonic characteristics of the sequence in the framework of Italian tectonics and the implications for future earthquakes in the same region.
