The giant sinkhole opened between the two houses in New Port Richey, Florida on September 5, 2018, and is 20 feet deep and 40 feet wide.

Sinkholes form when ground water circulates through and dissolves certain types of soft rock, usually limestone, salt, gypsum, anhydrite and dolomite. As the rocks dissolve, caverns form and eventually, there is not enough strength to support the land above, triggering a sinkhole like this Wednesday in New Port Richey:

A sudden collapse can vary in size from a few feet to hundreds of acres and can range from 1- to 100-feet deep. Human activity can also trigger sinkholes, where groundwater pumping, new construction and development and groundwater manipulation occur.
