Sinkhole – Guatemala
The 2007 Guatemala City sinkhole is a 100-metre deep sinkhole which formed in Guatemala City in 2007, due to sewage pipe ruptures. Its collapse caused the deaths of five people, and the evacuation of over a thousand. Several rainstorms also contributed to the sinkhole’s collapse, as stormwater percolated into the ground, further dissolving the rocks beneath Guatemala City.
Harwood Hole, New Zealand
