if they know its on a major fault line why do they still build there and particularly high rise buildings?

Yeah why is San Francisco there?
Turks have been paying an earthquake tax to retrofit etc
and it has been .... embezzled.
and I only include this to educate
Lovely little Beebster was twittering about some buildings fall and some dont,
and I severely emailed ( I cant stand fluffies without physics O level 'doing' science)......
Do buildings fall down because they are resonating at their natural frequency?
"If the earthquake vibrations push on a building at or near its natural frequency, it will begin to resonate, which causes the building to move with greater amplitude until some part of the building collapses or fails and the building falls apart."
google it. answer Yes. Time surely for a structural enginer and or seismologist to give an opinion? ( noI me: I am not one
Oh whilst I am at it:
Clive Myrie last night - "People are praying that more miracles.... "- eyes bulgy with tangible sympathy etc
No muslims dont "do" intercessionary prayer ( praying for things). Ask Ali Maqbuul - he should know. Bad mistake. Like saying Christians are doing salah. They dont. They do something else.

Idea confirmed
I saw a photo of a wrecked building and atop was a table with an undisturbed vase on the table
So basically there is a maximal disturbance on the ground and a zero ( half a wavelength) at the table - say 10m.
so the wavelength is 40m. All you have to do now is estimate the frequency of the earth waves - I thought 5 per second was OK - and you can calculate speed of propagation of the earth quake waves.
v = f l - I am sure someone asked, they asked

You also get earth liquefaction when it wobbles
