Earth science > Seismology 
strain rate
Earth science; Seismology
Strain measurements are computed from observed changes in length on the Earth's surface, commonly along multiple paths. Because the changes in length are observed over varying ...
root mean square
Earth science; Seismology
Square root of the mean square value of a random variable.
torodial mode
Earth science; Seismology
Spherical motions of the entire Earth that involves purely horizontal twisting of the Earth.
foreshocks
Earth science; Seismology
Smaller earthquakes preceding the largest earthquake of a series concentrated in a restricted crustal volume.
aftershocks
Earth science; Seismology
Smaller earthquakes following the largest earthquake of a series in a restricted crustal volume. Originates within less than one fault length of the main rupture, and is part of ...
creep
Earth science; Seismology
Relatively slow, quiet movement along a fault. It is sometimes called "seismic creep" to distinguish it from the slumping of rock or soil on slopes (which is also known as creep), ...
surface waves of earthquakes
Earth science; Seismology
Seismic waves that follow the Earth's surface only, with a speed less than that of S-waves. There are two types of surface waves - Rayleigh and Love waves.
