Chances for collapse of modern houses in earthquake?

I'm curious to know the chances of complete collapse of single storey houses constructed following the modern engineering practices ie. Dry pack rubble foundation+RCC belt+Clay/Concrete brick wall+RCC lintel+RCC roof. How strong earthquakes ie.

Is there any structural importance to sunshade?
