According to Sam Bonis, a geologist at Dartmouth College, leaking pipes went unfixed long enough to create the conditions necessary for sinkhole formation because of city zoning regulations and building codes. [3] Bonis also says that the Guatemala City sinkhole is a misnomer: sinkholes have natural causes, but this one was mainly artificial. [3]
The sinkhole was created by fluid from a sewer eroding uncemented volcanic ash, limestone, and other pyroclastic deposits underlying Guatemala City. [1] [2] The hazards around the pipe have since then been mitigated, by improved handling of the city's wastewater and runoff, [3] and plans to develop on the site have been proposed.
The 2010 Guatemala City sinkhole. 2007 Guatemala City sinkhole – a 100 m (330 ft) deep sinkhole which formed in 2007 due to sewage pipe ruptures. 2010 Guatemala City sinkhole – a disaster in which an area approximately 20 m (65 ft) across and 90 m (300 ft) deep collapsed, swallowing a three-story factory.
Sinkholes can range in size from a few feet wide to hundreds of acres, and anywhere from 1 to 100 feet or more deep. Sinkholes can swallow up cars, parts of roads and even houses.
This sinkhole, which is classified by geologists as either a "piping feature" or "piping pseudokarst", was 100 metres (330 ft) deep, and apparently was created by fluid from a sewer eroding the loose volcanic ash, limestone, and other pyroclastic deposits that underlie Guatemala City.
In recent weeks, huge sinkholes, several meters (feet) deep, have led the municipal government to declare a state of emergency. Some 1,200 people of total 55,000 population are at risk of having ...

A sinkhole that formed on the eastbound side of I-80 near Wharton, New Jersey caused traffic snarls on the busy highway, about 40 miles west of New York City. Westbound lanes were unaffected.
