Tectonic stress and seismogenic faulting in the area of the 1908 Messina earthquake, south Italy
No full textStress inversion of the twenty best-quality earthquake fault-plane solutions available in the area of the 1908 Messina earthquake showed a nearly uniform extensional regime with σmin constrained between N284°E and N312°E, coinciding with the direction of extension derived from geostructural data. The misfits of earthquake nodal planes and related slip vectors to the stress tensor allowed us to identify the fault planes of thirteen of the earthquakes used for inversion. In particular, the fault plane of 1908 earthquake was found in the north-trending east-dipping nodal plane of the focal mechanism. These findings and strain tensor estimates performed with the same dataset lead us to propose that in spite of stress uniformity detected over the study area the seismic strain orientations change significantly in the crustal volume under investigation due to different fault orientations in the different sectors. However, when comparing strong earthquakes with background seismicity in a given sector the strain orientations are found to be similar.Published1-5partially_ope

Fatal cranial injury in an individual from Messina (Sicily) during the times of the Roman Empire
No full textForensic and archaeological examinations of human skeletons can provide us with evidence of violence.
In this paper, we present the patterns of two cranial lesions found on an adult male (T173) buried in a
grave in the necropolis ‘Isolato 96’, Messina, Sicily, dating back to the Roman Empire (1st century BC - 1st
century AD). The skull reveals two perimortem traumatic lesions, one produced by a sharp object on the
right parietal bone and the other one on the left parietal bone, presumably the result of a fall. The
interpretation of fracture patterns found in this cranium are an illustration of how forensic approaches
can be applied with great benefit to archaeological specimens.

Viaggio a Gibellina Vecchia
No full textIl contributo intende approcciare la questione paesaggistica attraverso una riflessione, propria del discorso geografico, sulla funzione che può assumere l’heritage nella lettura dei luoghi, nello studio delle comunità.
Il riferimento teorico del contributo risiede nella riflessione, propria della geografia culturale, che individua nel paesaggio certamente un’estensione spaziale definibile – per morfologia ed estetica – ma vieppiù un costrutto epistemologico complesso, vero mediatore gnoseologico nella dinamica di percezione e di rappresentazione del sistema di relazioni fra uomo e spazio. nel contributo si tenta di fornire una chiave di lettura alla poliedricità e alle complessità interpretative che offre il Cretto, la grande opera di Land Art attraverso cui l’artista Alberto Burri è intervenuto a Gibellina, uno dei comuni devastati dal sisma che, nel gennaio del 1968, ha stravolto la Valle del Belìce
STORIA DI UNA FRATELLANZA CULTURALE SORTA DALLE MACERIE DEL TERREMOTO DI MESSINA
No full textAll'alba del 28 dicembre del 1908 una violenta scossa tellurica in soli trenta secondi squassò la zona dello Stretto e distrusse completamente Messina. Il tremendo terremoto di Messina, le storie di solidarietà e coraggio, di fronte alla violenza del moto sismico (decimo grado della scala Mercalli) si aggiunse quella del maremoto che circa dieci minuti dopo la scossa riversò diverse ondate sulla città. Tutto ciò avvenne in un ora in cui non era molto facile trovare scampo ed in un luogo ove la gente viveva ammassata in costruzioni che non poggiavano su solide basi. La stima approssimativa fu di 60.000 vittime
Analysis of Earthquake Damage to Ancient Buildings on the San Raineri Peninsula, Messina, Sicily
No full textA study aimed to shed some light on building collapse caused by the
strongest earthquakes in the San Raineri Peninsula (Messina) is here reported.
Although a compilation of structurally damaged buildings is widely reported in historical
sources, the interpretation of seismic collapse has often been doubtful or ambiguous.
We therefore performed an exhaustive and detailed review of seismic effects
caused by the 1783 and 1908 earthquakes on the peninsula buildings. Geological and
geotechnical data were also collected on the peninsula. The results of boring data
reveal high seismic vulnerability for the peninsula in some areas. The study shows
that the ancient buildings were damaged by settlement due to soil liquefaction rather
than by seismic shaking of the large walls. The obtained results show that further
investigations must be carried out in this area for a correct town planning of the
peninsula.Published2067-20793.10. Storia ed archeologia applicate alle Scienze della TerraJCR Journalrestricte
