Summary Introduction

The difference between the terms seismograph and seismogram.

Introduction:

Both seismograph and the seismogram are the tools that are useful for measuring the location and magnitude of an earthquake.

Explanation of Solution

The difference between the terms seismograph and seismogram is as follows:

No.	Criteria	Seismograph	Seismogram
1.	Definition	The term seismograph refers to an instrument that measures the intensity and magnitude of Earthquake.	The term seismogram refers to the record that is measured by seismograph.
2.	Function	Seismograph measures the vertical and horizontal motion of the Earth’s surface that is caused by an earthquake.	A seismogram is measured as the function of time, and based on the seismogram, the scientists publish the intensity of an earthquake.
