Earthquake risk

Earth science; Seismology

The expected (or probable) life loss, injury, or building damage that will happen, given the probability that some earthquake hazard occurs. Earthquake risk and earthquake hazard are occasionally ...

Reflection

Earth science; Seismology

The energy or wave from a seismic source that has been returned (reflected) from an interface between materials of different elastic properties within the Earth.

Runup height

Earth science; Seismology

The elevation of the water level above the immediate tide level when a tsunami runs up onto the coastal land.

Microzonation

Earth science; Seismology

The division of a town or county into smaller areas according to the variation in seismic hazard.

Wavelength

Earth science; Seismology

The distance between two successive crest or troughs of a seismic signal.

The distance between any two parts of a reference plane (for example, a sedimentary bed or a geomorphic surface) offset by a fault, measured in any plane. Separation is the apparent amount of fault ...

Stress drop

Earth science; Seismology

The difference between the stress across a fault before and after an earthquake. A parameter in many models of the earthquake source that has a bearing on the level of high-frequency shaking that ...
