In this paper we analysed the historical and instrumental seismicity of the seismic district “Penisola Salentina” (Salento peninsula) in the southern part of the Apuliaregion, making use of the most recent seismological database. Relocation of available dataset points out that the events are spatially distributed over a belt of deformation that approximately corresponds to Soglia Messapica (Taranto-Brindisi depression). Besides, computed source characteristics indicate dextral strike-slip solutions with an approximately E-W orientation that seismologically confirm previous geodynamic studies indicating a NE-SW extension in the Taranto-Brindisi depression. In particular, the tensional stress associated to the present seismic activity could be the consequence of the relaxation of the buckling process following the extensional re-arrangement of the Apenninic belt masses. Moreover attenuation QPvalues obtained in this study are much greater than those inferred in other parts of Italian peninsula; this result agrees with previous macroseismic investigations and indicates a greater efficiency of the studied area in the transmission of body waves.
Sociological and anthropological productions that take the city as their object of investigation have met new approaches in Brazil, especially since the 1990s. This paper aims to discuss the recent theoretical and empirical trajectories of research proposals as their authors take the city to the spotlight. This scientific endeavor analyzes a corpus of theses and dissertations produced by students of the Sociology Graduation Program of the Federal University of Ceará, in Brazil, as such works encompass shifts and trends in predominant theories and methods of the Social Sciences in Brazil over the past two decades. They demonstrate an increasing interest for the microsociological look towards the urban, which we argue to be an effect of the influence of Anthropology in the theoretical and methodological approach of research objects. From the set of selected works, the city is composed by territories cross-cut by a strong dimension of power and conflict, as an influence of Political Geography. French Sociology and Historiography contribute with theoretical perspectives that prioritize the senses of creation and insubordination, thus attributing to the practice of diverse social actors in urban places. In the set of works, the neighborhood unfolds as a microcosm of social practices, embedded with multiple senses of belonging and spatial conflicts, which are expressive of a wider social struggle.
