Abstract: A system and method for providing a partial level of saturation to a mass of sand, through generation of gas bubbles, as a way to prevent liquefaction during earthquakes. The system includes a solution that is operable to generate gas bubbles and a solution generator that prepares the solution. A conduit delivers the solution to the sand, so that the solution generates the gas bubbles during and after being delivered to the sand. A probe may be used to determine whether the sand is susceptible to liquefaction before the solution is delivered and to assess a change in degree of partial saturation after the solution has been delivered.
