Short summary

Earthquake-induced soil liquefaction poses a significant global threat. Microbially induced desaturation and precipitation (MIDP) via denitrification is a potentially sustainable, non-disruptive bacteria-driven ground improvement technique under existing structures. We developed a next-generation biogeochemical model to understand and predict the behavior of MIDP in the natural environment to design field-based hazard mitigation treatments.
