A measure of the magnitude of a local earthquake originally defined by Charles Richter using the maximum amplitude recorded by horizontal-component seismographs.
Industry:Natural environment
A sloping faulting on which the block above the fault has moved downward relative to the block below.
Industry:Natural environment
The magnitude of an earthquake determined from seismic moment.
Industry:Natural environment
A fault with both strike-slip and dip-slip movement.
Industry:Natural environment
The magnitude of an earthquake determined from surface waves.
Industry:Natural environment
A strike-slip fault on which displacement of the block opposite the observer is to the right.
Industry:Natural environment
That part of the earth between the crust and the core.
Industry:Natural environment
A fault on which the movement is parallel to the fault's strike.
Industry:Natural environment
The largest earthquake, usually expressed in magnitude, judged to be possible in an area.
Industry:Natural environment
A dip-slip fault in which the upper block moves over the lower block.
The dip of some thrust faults is low and the displacement may be tens of miles.
