Movement in the earth's crust, as in earthquakes.
First P-wave then S-wave
p-waves
it is a seismic wave of election
seismograph ...
A seismograph is placed under the ground. Somewhere not to close to the surface, as when something on the surface moves, then it would be recorded on the seismograph. Something on the surface that moves can be a vehical driving along the road.
John Milne created the first modern seismograph.
Most of vibrations can be detected and recorded by sensitive instruments called seismograph, or seismometers. The record produced by a seismometer is called a seismogram.
yes it does because its faster and its the primary wave
The first waves to arrive at a seismograph station are primary waves, or P waves.
A seismograph can locate a seismic wave.

The seismograph measured the intensity of the seismic waves

P-waves, which may also be known as primary (as they arrive travel faster than other types of seismic waves and so are recorded on a seismometer first) or pressure waves as they propagate by the compression of matter.
