Now That's a "Heavy Rain"

I think this must be the result of more than a heavy rain folks.

GUATEMALA CITY, Feb. 23 -- A 330-foot-deep sinkhole killed two teenage siblings when it swallowed about a dozen homes early Friday and forced the evacuation of nearly 1,000 people in a crowded Guatemala City neighborhood.

Officials blamed the sinkhole on recent rains and flow from a ruptured underground sewage main. The bodies were found near the enormous fissure, floating in a river of sewage.

I'm sorry, but even a ruptured sewage main doesn't cause a hole 330 ft deep. Either this is a mine collapse, or given the nice circular shape the buildings were built over an incipient cenote (a "well" in a limestone formation).
