#aseismic

• Aseismic — Not seismic; a geographical region or zone characterized by the absence of earthquakes or by the occurrence of tectonic movements of negligible intensity. In structural engineering, the term is sometimes used (as a variant for antiseismic) to describe elements designed to withstand seismic shocks, though in geology it exclusively indicates a lack of seismic activity.
• Aseismicity — The structural property or characteristic of a geographical region or tectonic zone of not experiencing significant earthquakes or seismic activity over long periods of time; stable absence of telluric movements. In civil engineering, the term can describe the quality of a site or the behavior of a stable ground that minimizes tectonic risks for built structures.
