Richter Scale vs. Seismograph: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 14, 2023
The Richter Scale measures earthquake magnitude, while a seismograph is an instrument that records seismic waves.

Key Differences

The Richter Scale quantifies the energy released by an earthquake, providing a numerical magnitude. In contrast, a seismograph is a tool used to detect and record the vibrations caused by seismic waves during an earthquake.

The Richter Scale provides a scale, typically from 1 to 10, to categorize the strength of earthquakes. A seismograph, however, produces a seismogram, a visual record of the duration and intensity of seismic waves.
