The most significant damage and loss of life is limited to the one 17-story building that fell over.
Estimates are that there were over 300 souls in the building at the time of the quake. Latest info is that 18 are confirmed dead. But over 100 are still missing. So...the death toll is likely to climb significantly.
There was another bank building that slumped over (didn't fall completely), but no one was inside at 4am.
There were also a handful of private homes that suffered significant damage, but no serious casualties.
