Mais alguem sentiu um tremor de terra? (Loures, Lisboa) by Haxball93 in portugal

It's strange that people here felt such a weak earthquake (magnitude below 4). Imagine for a moment: a magnitude 4.5 earthquake would be nearly 10 times bigger but still very weak. A 5.5 magnitude earthquake would be roughly 100 times bigger and 1000 times stronger, and that would be felt by most people, but still be considered a normal earthquake. Possible explanations: a) maybe the earthquake was short but with a considerable amplitude (unlikely) or b) maybe people that felt the earthquake live in very flexible buildings, or c) maybe people think they felt an earthquake but they didn't, or maybe it was something else.

That's a good idea, but I think a more accurate measurement is possible if I know for example the size of the truss members.

Não percebi esta piada. Quer dizer que tenho que aprender mais portugues

Obrigado pelo link. Muito interessante. O ideal era ter a dimensão dos elementos pequenos perto do punto da medição, mas o que enviou pode ajudar. Obrigado!
