The earthquake events that occurred in the last 25 years caused widespread liquefaction that resulted in significant loss of life and economic overburden. Considering the increased amount of data, the Standard Penetration Test-based liquefaction case history database is updated with new data by employing an improved processing perspective in case history processing, including new rod length (CR) corrections, and updated hammer energy ratios (CE), along with a new set of parameters. The new SPT-based liquefaction triggering field case history database is a collection of a larger suite of 334 case histories, including new and re-assessed legacy case histories, improving the data in the CSR range of 0.3–0.6. The updated database is used to develop a probability-based liquefaction triggering predictive model using the maximum likelihood analysis. This paper presents details regarding the updated database and model development efforts, which provide new correction terms for duration, overburden stress, and fines correction.
