You're right about it.
Those older buildings did not fall because of Seismic Isolation system. In old buildings (till 1900s probably) foundations are anchored to the ground by three layers of stones, where the deepest level consisted of small stones laid out relatively loosely. This layer absorbs the first surge of an earthquake’s devastation powers. On top of that is a layer of big fat even stones placed without any mortar, called Orthostats. And finally, it’s the base of the structure standing above the ground. This multi-layer foundation perfectly balances out the earthquakes’ forces while protecting the building above.

Yes they were. Modern man is also very much incapable of affording such houses. Stone is much more expensive now. But then I look at some of the houses people build in the Himalyas with layers of wood and stones. Their structures easily withstand many earthquakes in the mountains.
These earthquake-resistant structures lack metal and mortar, allowing them to flex as needed during a tremor.
They are called 'Kath Kuni' in the Himalyas

beautiful! the typical Ottoman houses are also built with wood and stone, which keeps cool in summer and warm in winter. 👀

Actually, I've read it somewhere that this technique was brought up to the Himalyas from Istanbul in ottoman times when India and Turkiye used to have free trade by road..
