Pronunciation: [fˈɒltla͡ɪn] (IPA) 
Faultline, also known as a geological fault, is a fracture or crack in the Earth's surface where tectonic plates meet. Synonyms for faultline include a seismic zone, a fracture zone, a rift, a break, or a shift. These terms describe the potential for movement or instability in the ground as tectonic plates shift and slide against each other.
