seismicinduced

Seismicinduced is a rarely used term describing phenomena or processes that are initiated by seismic activity, particularly the ground shaking produced by earthquakes. In standard technical writing, the phrase “seismically induced” (often written as two words or hyphenated) is preferred. When used, seismicinduced serves as an attributive descriptor for effects directly triggered by seismic energy, as distinct from those caused by weather, weathering, or human activity.

Seismicinduced phenomena include, most commonly, landslides triggered by shaking on unstable slopes, liquefaction where saturated soils lose strength and flow, surface fault rupture, and ground settlement or distortion near foundations. Seismicinduced tsunamis can occur when large undersea earthquakes displace ocean water. Some effects involve changes in hydrology or soil structure, altering permeability and stability of soils and structures.

Assessment relies on seismological data and ground-motion modeling to estimate potential intensity at a site, often expressed as peak ground acceleration or spectral acceleration, and on intensity measures such as the Modified Mercalli or similar scales. Engineers use these inputs to evaluate hazard, design resistant structures, and implement mitigation strategies.

Mitigation focuses on land-use planning, slope stabilization, soil improvement, deep foundations, drainage control, and, where feasible, early warning. Retrofitting and strict adherence to seismic design codes reduce the risk of seismicinduced damage to buildings and infrastructure.

Note: The compound form seismicinduced is uncommon in formal literature; more widely used are the phrases “seismically induced” or “seismically induced hazards.”
