Question

What is the difference between a seismograph and a Richter scale?

Answer 1

Step 1: Definition

1. A seismograph seems to be a device that detects and records earthquakes.
2. The Richter scale is a numerical measurement that is used to assess the strength or magnitude of earthquakes.

Step 2: The difference between a seismograph and a richer scale

Seismograph	Richter scale
A seismograph, also characterized as a seismometer, seems to be a device that detects ground motions, such as seismic waves produced by disasters, volcanic activity, as well as other seismic occurrences.	The Richter scale provides a number depending on the amount of energy produced by the earthquake.
Seismologists utilize seismic wave records to explore the Earth's core and perhaps to locate as well as quantify earthquake causes.	The Richter scale is a base-$10$ logarithmic scale, indicating that such an earthquake measuring $5.0$ seems to have a shaking amplitude $10\mathrm{times}$ larger than one of magnitude $4.0$, as well as corresponds to $31.6\mathrm{times}$ the energy released.
Many sensitive contemporary seismographs nowadays can detect negative magnitude earthquakes.	The scale is labeled from $1-10$, with $0$ serving as the baseline against which the energy is measured, the truth is that the scale has no lower limit.

Therefore, a seismograph is what scientists have been using to quantify the earthquake, as well as the Richter scale is indeed a technique to put the information or findings into context.
