Good to hear your family are fine.Thanks for asking. Yes. They barely noticed it. They live in Western Turkey.
The combined death toll will likely go over 30,000 and there will be at least 150,000 injured. Southeast Turkey is relatively poor and most buildings are cheaply built 4-7 floor brick buildings. In rural, there are still mud brick buildings. Northern Syria is even worse. So even an earthquake of magnitude 5 is problematic there. Two earthquakes of magnitude 7.8 are horrific for those regions.
People living in mud huts are pretty safe even with big earthquakes. The problem is with those small multi-storey buildings where constructors skipped safety regulations, or they didn't exist. That's why even modest earthquakes can be devastating in some parts of the world.
