The liquifaction has stopped along with the earthquake. I assume the ground would be substantially more supportive for the jacks now that we the shaking has stopped.
So far the lack of reports of injuries or deaths is temporarily satisfying though I fear that may change. I suspect, from one of the photos, that the lowest levels that gave way are open parking structures lacking sufficient bracing. The rest are remarkably together though the people and contents were certainly in for a thrashing.
Correct, Dave. Most likely no liquefaction involved, but rather typical soft story failure. I'm guessing that the ground floors were commercial. Corner columns were knocked out, and the box above rotated. Buildings of 4-10 stories are more susceptible to this type failure than shorter or taller buildings.
