I guess that's a disadvantage of beautiful old buildings.
I think, one of the last places you want to be during an earthquake, is inside an un-reinforced multistory stone or brick building.
Those types of buildings are able to stand for centuries, but only if the forces on them are almost entirely gravitational (vertical).
When the forces are from an earthquake (horizontal), down they can come.
And, stones and bricks falling on people, is not good.
Additionally, I think it is a hard problem to retroactively reinforce those types of old buildings.
What could you do, build buttresses onto them, like on cathedrals?
Probably, there is some lateral resistance, when many of them are built one against the next.
But, that doesn't help if the lateral force from an earthquake is perpendicular to the row.
I think, the worst case is when, such a building is freestanding and vertically slender.
What would happen, if there was a big earthquake in Pisa (just my ignorant intuition/speculation)?
---------------------------------------------------------
I think everyone intuitively understands the situation.
One brick, set, largest face on the ground, is stable.
Two bricks, one on top of the other, is less stable.
A tower of three bricks, is even less stable.
A tower of four bricks ..

Yes, we felt it this time
Even if I live about 180Km north of the epicenter of earthquake, our house was dancing for few seconds yesterday night. My wife was still up and she wake up me and my son.
Earthquake is still lasting but intensity is low at the moment.
Unfortunately there were 6 deaths 4 of which were workers working on a factory open h24. A complete area of the factory went down even if it was a modern one. Someone will have to respond of that. The other 2 were old woman, one died for the fear, and the other under the roof.
The area hit by the earthquake is full of ancient buildings almost all from 14th century. Many churches wend down or partially broken.
I hope it will stop soon.

Glad you are alright Eros and it is remarkable the deaths were so low. They said it was the strongest in the area since the 1300's, Wow!
I bet the death toll was so low because it struck in the middle of the night on Sunday morning.
My guess is that most of the collapses were in old public structures.
Imagine how much worse it would have been, if it struck at noon on Monday (or Sunday morning --> churches).

Again and again. All the day.
Two strong Earthquakes plus many many little one almost every 30 mins
17 deaths so far, 14000 out of their houses.

That's a lot of earthquakes, Eros. Does this happen often in Northern Italy? This seems to be exceptional since you have lost a large number of historical buildings which have stood for 4-500 years.

It is hitting in other areas as well that normally do not get hit. I am sorry to hear about all the quakes, deaths and damage.

6605 earthquakes in the past 30 days
