The type of study used was research and development which aims to develop digital-based physics learning packages that are integrated with disaster mitigation education on the basic competencies of waves in high school education units. This research was conducted using ADDIE development research procedures. The results of research on the analysis of liquefaction potential based on microtremor data using the Ground Shear Strain method, zoning indication of liquefaction potential due to geological conditions and seismic potential, generally Padang Lekat Village and Pasar Ujung Kepahiang Village are areas that have no potential to experience liquefaction. However, there are a number of locations indicated by potential liquefaction, although not significantly. Learning Package Book "Learning Liquid Strain" compiled based on the analysis of liquefaction potential based on expert validation is appropriate to be used as a learning medium for seismic and liquefaction waves. In its application with distance learning, the compiled learning package book has been able to improve critical thinking skills in students even though the N-gain improvement obtained is still in the low and medium categories. Keywords: Liquefaction, Learning Packages, Critical Thinking, Wave. Introduction Physical learning is directly associated with the natural environment and studies of natural phenomena as matter and forms of energy and as the relationship between them (Kanginan, 2013). It is in line with the many disasters phenomenon that exist in students’ environment or Indonesia on a larger scale. As one of the countries through which the ring of fire lies between the three tectonic plates of the world, Indonesia is a country prone to many catastrophes, including the Bengkulu province.
