> Many seismologists thought the East Anatolian Fault—the one involved in the Turkey-Syria quakes—was likely to produce a maximum magnitude of 7.4 or 7.5. But the February 6 earthquake was a 7.8—about four times bigger on the logarithmic scale of earthquake magnitudes. So it is possible that some structures built to code in Turkey may simply have experienced more force than they were built to withstand, Taciroglu says.

There were probably some such cases, anyway this is as well interesting:

From https://www.nbcnews.com/news/world/erzin-turkey-earthquake-b... :

The city that didn't collapse: How Erzin became a haven from Turkey's earthquake - Residents and officials say Erzin suffered no deaths and saw no buildings collapse, and they credit a long-standing policy not to allow construction that violated the country’s codes.

From https://en.wikipedia.org/wiki/Erzin,_Turkey :

Erzin was the sole district of Hatay Province to have none of its buildings collapse in the aftermath of the 2023 Turkey–Syria earthquake, despite being closer to the epicenter than other cities such as Iskenderun and Antakya which suffered greater damage. The mayor, Ökkeş Elmasoğlu claimed it was due to strict construction of housing; the district mostly consists of single houses, local authorities prohibited unsafe and substandard construction to a much greater degree than nearby areas, and apartment blocks do not have many floors. Even older structures such as houses from 60 years ago survived the earthquake.[4] Additionally, the city had fared relatively well during previous earthquakes. However, engineers and scientists (such as Omer Emre) attributed the town escaping unscathed to geological factors, such as Erzin's relatively higher sea level compared to surrounding towns, and it being built upon harder ground, consisting of bedrock and coarser grains than sand, compared to softer, water-laden sediments like that of cities to the south.



Following strong building code certainly helps.

However, I feel we'd be remiss to not investigate the geology of the different places. Are they similar, different, one alluvial one on bedrock? Seeing the iconic olive grove have a 30 meter collapse, I'm not sure what kind of building would survive that upheaval, unless the pilons went deeper than that into bedrock.


I feel we'd be remiss not to read to the end of a paragraph:
