This main topic of this assignment is post-earthquake soil liquefaction and its impact on the soil, buildings, nearby infrastructure and human lives. Liquefaction itself, her triggers and consequences will be defined and explained. The assignment also covers the problem of liquefaction assessment considering used methods to assess the probability of a certain soil to liquefy. Various methods can be used to assess liquefaction potential, and every one of them is based on different parameters. It is always recommended to use several different methods in the assessment process to get the most reliable and high-quality results which will help us determine appropriate safety measures for affected areas. This assignment also mentions the earthquake in Petrinja that happened in December 2020, which caused soil liquefaction and is one of the most recent phenomena in Croatia. Aside from Croatia, this earthquake was felt by several neighboring European countries. Based on the available data at the time, researchers did an analysis on liquefaction potential and created a map consisting of noted consequences and future liquefaction potential of the area.
