sinistral fault; left-lateral fault
Geological term for a strike-slip fault where the opposite side moves to the left relative to the observer.
Many sinistral faults are observed in this region.
The topography changed due to the activity of a left-lateral fault.
Compound of 左 (ひだり, 'left') + ずれ (連用形 of ずれる, 'to shift') + 断層 (だんそう, 'fault'). The term directly describes the leftward displacement characteristic of this fault type.
