(Earthquakes question). What is the relationship of the motion on a seismograph versus the true motion of the ground where the seismograph is located?Whats the relationship motion on a seismograph, versus true motion of the ground where the seismograph is loca?it's oppositeWhats the relationship motion on a seismograph, versus true motion of the ground where the seismograph is loca?The seismograph measures the ACCELERATION of the earth. Acceleration is how fast the velocity of the ground increases (or decreases).
To find out how far the ground actually moves in feet, you must double integrate the seismograph signal.
The first integration of the acceleration yields the velocity.
The second integration yields the translation or position movement.Whats the relationship motion on a seismograph, versus true motion of the ground where the seismograph is loca?no
