All of the piles driven into the bedrock literally rotted into dust, not only did it collapse, it collapsed into the holes left by the soft sand and destroyed pilings. When all that supports your multi metric ton structure is sand, it won't last long.
It literally sank into the earth.
Sure looks a lot like OKC to me in the pictures.
You’re way to quick to give excuses for this. Glownigger!!!!
Sand can't melt steel beams!
Saltwater can, and did. Guess you've never dug a hole at the beach and watched it fill with water have you?
Stop being a bot, use your mind for something else, internet porn is rotting it.
To add to this, inadequate waterproofing maintenance causes three major problems:
1) Saltwater corrodes rebar and i-beams, making them vulnerable to catastrophic failure.
2) Water displaces sand and doesn't really compress. This causes it to wash out the sand under the building...until the water leaves and all you have is a void.
3) Voids, aka sinkholes, lead to catastrophic collapses because the building doesn't settle gradually...it goes from "everything is fine" to pancaking into the "new basement".
It sank pretty quickly. What’s that about.
What is liquefaction? Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking. Liquefaction occurring beneath buildings and other structures can cause major damage during earthquakes.
In this case, the pilings used for support literally rotted away to powder by the pictures I've seen, once the ground started shaking from the first impact, the rest of the sand liquified and brought it all down.
I'm a Californian, who learned a lot about liquifaction during the 89 quake. It applies here as well.
Yeah, nice try.
