I think the plastic ones are held up with PVC or fiberglass rods, probably brought in en masse by relief organizations.

The Anchorage quake of 1964 was a 9.2. I think they had vertical landmovement of around 35 ft (some places split and raised that far from the adjoining scrap of land).

It's hard to comprehend.
