Tilted Building, Adapazari
The city of Adapazari was constructed on the site of an
ancient lake bed. So the local ground is made up from layers
of sand and silt.
The earthquake shook these soft soils causing them to weaken
and behave like a liquid (liquefaction)
so that they could not support buildings above.
This picture shows a building that tilted over when the foundation
on one side sunk into the soil below.
