Short summary

Any sinkhole occurring in a highly active city provokes chaos and disturbance. In the city of Quito a big sinkhole appeared in a critical road interchange called El Trébol. For a few months the city came close to collapse with its traffic in this zone and a state of emergency was declared. During the recovery and reconstruction of the site, the cause was able to be determined as the combined negligence of monitoring of older subterranean infrastructure as well as high precipitation.
