The underground motion of a P-wave usually effects the us less than ones near or on the surface.
By definition, friction is opposite of the direction of motion.
The direction of the force of friction is opposite of the direction of the motion.
Horizontal force is motion parallel to the ground.
Seismograph.
ten times as much for each magnitude increase; thus a magnitude 7 is 1000 times more displacement than magnitude 4
The underground motion of a P-wave usually effects the us less than ones near or on the surface.
Vertical motion is the motion that is perpendicular to the ground.
0.3 magnitude
0.3 magnitude
is motion that is perpendicular to the ground
horizontal motion
They both spin on an axis.

The Richter Scale is what measures the ground motion from an earthquake.
By definition, friction is opposite of the direction of motion.
They're equal.
The direction of the force of friction is opposite of the direction of the motion.
