This has made a huge mess for the residents to clean up. I heard on the news that homes have been damaged by subsidence in areas of earthquake-caused liquefaction like this.
It would have been a glorious Spring day in Christchurch had it not been for the magnitude 7.1 earthquake at 4:30 am. All the water and silt you can see covering the street in this photo erupted from the ground following the earthquake.
These were scattered across the park.
Sand volcanoes put the silt all over the road.
Cracks in the roads and foot paths were surprisingly hard to find given the strength of the earthquake.
