Seismology
fault-plane solution
Earth science; Seismology
An analysis using stereographic projection or its mathematical equivalent to determine the attitude of the causative fault and its direction of slip from the radiation pattern of seismic waves using ...
point source
Earth science; Seismology
An approximation used in describing the waves radiated from a seismic source.
least-squares fit
Earth science; Seismology
An approximation of a set of data with a curve such that the sum of the squares of the differences between the observed points and the assumed curve is a minimum.
landslide
Earth science; Seismology
An abrupt movement of geological materials downhill in response to gravity. Landslides can be triggered by an earthquake or other natural causes. Undersea landslides can cause tsunamis, such as the ...
brittle-ductile transition
Earth science; Seismology
A zone within the Earth's crust that separates superjacent brittle rocks from subjacent ductile rocks. Commonly identified as the zone defining the deepest earthquakes in the crust.
hot spot
Earth science; Seismology
A volcanic center, 100 to 200 kilometers across and persistent for at least a few tens of millions of years, thought to be the surface expression of a persistent rising plume of mantle material. Hot ...
shield volcano
Earth science; Seismology
A volcano in the shape of a flattened dome, broad and low, built by flows of very fluid basaltic lava or by silicic ash flows.
