Natural distaster caused by human undeground infrastructure?

Question

Anyone knows of any natural distaster caused by human undeground infrastructure? For exemple, a city collapsing because of the underground structure.

I have found documentation about the underground fire in Pennsylvania that has been burning for several decades now, forcing all residents to evacuate their homes due to the toxic gases.

Answer 1

Depends on what you mean by natural and underground.
Several cities, including San Francisco in the the 1906 major earthquake and the most recent one had much more damage that otherwise might have been the case because man filled in an area (underground earth) and then built on it and it turned to slop in the earthquake.
If someone builds underground structures and they collapse, how is that natural? The nearest examples would be mining under a town or other area and the mines collapse or burn, which has happened in England and Pennsylvania or where water being drawn out of the ground has caused lowering and shifting of the ground as seems to be the case in New Orleans (lowering of levees made them more vulnerable.)

Answer 2

200 homes on the south side of Edinburgh had to be demolished, in the year 2000, when they began to collapse into old caverns which had been left by mining for limestone.
