Pressure from underground sources of irrigate would separate and suspend the grainy particles, reducing the friction flanked by them. As of September 2005, it has been exposed that it is the attendance of salty so as to is largely responsible. The stability of the colloidal quicksand is compromised by the attendance of salty, rising the likelihood of sand flocculation and the formation of the high viscosity regions of sediment responsible intended for quicksand's "trapping" power. Quicksand can be establish internal (on riverbanks, near lakes, or in marshes) or near the coast.

One area notorious for its quicksands is Morecambe Bay, England. As the bay is very broad plus shallow, a being attentive by the quicksand would be exposed to the danger of the returning surge, which can come in rapidly. After a lady entrapped in quicksand in Alaska was drowned by rising tide even as rescuers tried to free her, better rescue techniques were urbanized.

These built-in a device made of a irrigate pump, hosepipe and perforated pipe so as to is second-hand to liquify the quicksand around the victim's legs to allow easy extraction, as well as the use of plywood sheets lain on the surface of the quicksand to support rescue workers.
