This is our worst scenario for buildings - unmortared piles of stone. Over the years, I have settled on 2 cm/s for this type of damage. People run out of office towers at 2 mm/s. Note that the floppy building in the background is still standing. I always look in the background of these pictures.
Obviously, they should follow Guatemala by using concrete and steel. Also the extremely heavy roofs of Peru are a factor.
