Definition

Tectonic Hazard: Threats to humans and infrastructure posed by tectonic processes.

Tectono-Seismic Hazards: The subset of tectonic hazards that occurs during and immediately after an earthquake.

Tectonic versus tectono-seismic hazards

Tectonics is the field of study within geology concerned with structures within the lithosphere (faults, folds), and particularly with the forces and movements that have created such structures. Tectonic processes include the various movements of the Earth’s crust, such as slip along active geologic structures, the vertical warping of the crust due to loading or unloading, or the movement of molten rock (magma). Such processes can be slow or rapid, although slow processes rarely result in life-threatening disasters (see  Geological/Geophysical Disasters).

Tectonic hazards result from three general types of physical processes:
  1. 1.

    Rapid fault rupture and its associated earthquake (see  Fault;  Earthquake). These hazards are often referred to as...
