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.
Lots of people were out and about in the streets checking on everyone after the earthquake. When it was clear that everyone was OK, the sand volcanos became the feature of interest.
Laura and Max return to Christchurch from their holiday in California and inspect the earthquake-caused sand volcano in their front lawn.
Yes, it was a joke. The tours, that is, not the yard filled with earthquake-caused sand volcanos. They were very real. You can see one covering the driveway in this photo. The signs read as follows. "Tours run 1/2 hourly. $5.25 admission. Eftpos unavailable." "If you think this is bad... you should see the back!"
