Ou seja foram detectados danos estruturais na Catedral de São Paulo Extra Muros em Roma. Neste momento estão a ser vistoriadas as principais igrejas de Roma e do Vaticano...
tudo isto que está a acontecer em itália é uma aprendizagem para os portugueses... estamos numa zona ativa.
a realidade Italiana é diferente da nossa, as falhas passam mesmo por debaixo do território, e o Stromboli o Vesúvio estão lá para nos lembrar disso, por cá é o famoso Gorringe que esta longe mas que já deu provas do que pode fazer.
a prevenção é a melhor arma, infelizmente com a mania do novo velho chique as casas são mal recuperadas apenas para inglês ver, as famosas gaiolas vão ao ar

Essa é a falha mais conhecida e com potencial mais destruidor, mas existem outras que já geraram eventos destrutívos como a falha de Benavente, a falha da Vilariça, Nazaré-Pombal, a do Vale do Sado, etc.
Para mim o vídeo mais espectacular de todos...

Smoking Gun: Classic Active Faults
Although many of Italy’s extensional faults are so young that there is frustratingly little evidence for geologists to map at the surface. They are called ‘blind faults,’ because the geologists are blind to their presence. But the faults near Norcia are an exception: They are remarkably clear and well developed features. Although uncertain, these faults probably last ruptured in 1703. One sees a landscape (below) very similar to the U.S. Basin and Range province of Nevada and Utah, which is also strewn with active extensional faults.
The features of extensional (‘normal’) faults are evident in the epicentral region. Repeated earthquakes have likely pushed down the basin in which Norcia sits, and uplifted the range in which Castelluccio is nestled. Wineglass valleys are unique to extensional fault-sculpted landscapes, and the giant landslide above Castelvecchio was probably triggered by a past Preci or Campi Fault quake. These faults are schematically shown by Galadini and Galli (2000).
Stressed faults continue to rupture, and they in turn change the stress
At this point it is unclear if only the Campi and Preci Faults ruptured, or if the Norcia Fault did as well. At M=6.6, surface rupture is likely, with 50-100 cm of slip expected, and so soon the answer will reveal itself by geological mapping, as well as by GPS, satellite radar, and seismic observations. What we can say at this point is that the M=6.6 shock is probably a compact, high-stress drop event, and that if it indeed ruptured the Campi and Preci Faults, stress has been transferred south onto the Norcia Fault, which is now in play.
Here is the figure we published on 26 October, revised to show the past 24 hours of new mainshocks and aftershocks (left). The 30 October 2016 shock probably struck on the Campi-Preci Faults, which, according to the INGV, was brought closer to failure by the 24 August 2016 M=6.2 shock (right).
In our judgment, the Norcia, Gorzano, Capitignano Faults could now be the next domino pieces to fall.

mais sismos violentos são de esperar num espaço de tempo de alguns meses.
A zona habitada de Norcia deve ser desabitada.
