strike-slip fault
strike-slip fault, also called transcurrent fault, wrench fault, or lateral fault, in geology,
normal fault
Normal, or Dip-slip, faults are inclined fractures where the blocks have mostly shifted vertically
reverse fault
In a reverse fault, the block above the fault moves up relative to the block below the fault.
p wave
A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology
s waves
In seismology and other areas involving elastic waves, S waves, secondary waves, or shear waves are a type of elastic wave and are one of the two main types of elastic body waves
epicenter
the point on the earth’s surface vertically above the focus of an earthquake.
focus
The focus is the place inside Earth’s crust where an earthquake originates
Richter scale
The Richter scale – also called the Richter magnitude scale and Richter’s magnitude scale – is a measure of the strength of earthquakes,
