|
coastal bulge
|
the region above a subduction zone in which the overlying continental plate flexes upward before slip on the subduction zone causes a major earthquake
|
|
debris avalanche
|
a fast-moving avalanche of loose debris that flows out a considerable distance from its source
|
|
far-field tsunami
|
a tsunami generated by an earthquake far from the point of impact of the wave
|
|
near-field tsunami
|
tsunami that strike areas adjacent to its point of origin
|
|
refract (waves)
|
redirection of the course of a wave passing from one medium to another (e.g. from air to water)
|
|
run-out distance
|
1) distance that a tsunami reaches inland
2) distance that an avalanche extends downslope |
|
run-up height
|
the height to which water at the leading edge of a wave rushes up onto shore. also used for the height to which a tsunami wave rushes up onshore.
|
|
seismic sea wave
|
another term for tsunami

|
trimline

tsunami
|
an abnormally long wavelength wave most commonly produced by a sudden displacement of water in response to sudden fault movement on the seafloor.

|
tsunami-laid sediments (TLS)
|
distinctive layers of sediment indicating the former occurrence of a tsunami
|
|
turbidity current

subaqueous flow of a plume of dense, sediment-laden water; may be initiated by a subaqueous slope failure or earthquake
|
|
wave period
|
the time between passage of two wave crests
