According to National Geographic, the maximum displacement along the fault between the two tectonic plates during the magnitude 9 earthquake in Japan was 164 feet (50 meters).

Answer:
Earth Makes Star Positions Change and Constellations Are Not Constant
Explanation:
As the planet rotates, the moon and stars appear to move across the sky just the way the sun does during the day.
Stars that you see at night belong to the Milky Way galaxy. The sun sits on one of the galaxy's arms and rotates around the center of the galaxy. Other stars in the galaxy follow their own orbits as well.
By studying seismic waves
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
