and this is part of the real world not really being shown much in the news.
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..

Great detailed explanation

Your bravery and determination to enter those territories, which are usually full of danger due to the tragedy and everything that happens in that event, is quite admirable. On the other hand, from a curious perspective, I suppose it was, is and should be fascinating to be able to appreciate the effect that arises from the force of nature and at the same time reminds us how fragile everyday life can be, and how everything can change in the blink of an eye.

It's possible those older buildings were built on the most stable ground. There's a big difference in how much earthquake damage is done to buildings standing on bedrock vs those built on dirt.

It certainly could be either. In the parts of America that have lots of earthquakes, buildings are designed to withstand them, but I can't speak to the situation in Turkey.
