Severe Storms Possible for Waterloo, Cedar Rapids Monday Evening, Sorry Iowa, Spring Seems To Have Been Canceled. This includes surveying land movement on the sides of the fault zone to see if there is an accumulation of energy. Many factors affect how susceptible materials are to liquefaction, but some of the most important requirements are the degree of water saturation, the size of the grains, and how well cemented they are.
