SNOLAB is a Canadian underground science laboratory specializing in neutrino and dark matter physics. Located 2 km below the surface in Vale's Creighton nickel mine near Sudbury, Ontario, SNOLAB is an expansion of the existing facilities constructed for the original Sudbury Neutrino Observatory (SNO) solar neutrino experiment.
Groundwater-related subsidence is the subsidence (or the sinking) of land resulting from unsustainable groundwater extraction.It is a growing problem in the developing world as cities increase in population and water use, without adequate pumping regulation and enforcement.
Garrison Creek was a short stream about 7.7 kilometres (4.8 miles) long that flowed southeast into the west side of Toronto Harbour in Ontario, Canada. [1] It has been largely covered over and filled in, but geographical traces of the creek can still be found, including the natural amphitheatre known as Christie Pits and the off-leash dog "bowl" of Trinity Bellwoods Park.
A subsidence crater is a hole or depression left on the surface of an area which has had an underground (usually nuclear) explosion. Many such craters are commonly present at bomb testing areas; one notable example is the Nevada Test Site , which was historically used for nuclear weapons testing over a period of 41 years.

The Sudbury Basin (/ ˈ s ʌ d b ə r i /), also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact structure on Earth , as well as one of the oldest. [ 1 ]
Land subsidence is a global issue and has different causes. Some are natural, like earthquakes , and some are caused by humans. In the United States, land subsidence from over pumping has affected 45 states and accounts for changes in over 17,000 square miles of land which is an area almost 10 times the size of Glacier National Park in Montana ...
Taddle Creek is a buried stream in Toronto, Ontario, Canada that flowed a southeasterly course about six kilometres long, from St. Clair Avenue west of Bathurst Street through the present site of Wychwood Park, through the University of Toronto, into the Toronto Harbour near the Distillery District.
