A fracture zone refers to a tectonic region where the Earth's lithosphere is subjected to stress and eventually cracks, leading to the formation of fractures or faults. Synonyms for this term may vary depending on the context, depth, and intensity of the fractured region. Some alternative phrases to describe a fracture zone are seismic zones, fault zones, break lines, rupture areas, crack zones, and shear zones. These terms are often used interchangeably when referring to geological features that are vulnerable to earthquakes, landslides, and other forms of natural disasters. Understanding fracture zones can assist in predicting and mitigating natural hazards in areas where human activity is present.
