Step 2: Calculate the Lag Time

The lag time represents the difference in arrival times between P-waves and S-waves.

Measure it accurately to determine the distance to the epicenter.

Step 3: Determine the Distance to the Epicenter

Using the lag time, look up the distance to the epicenter in a standard travel-time curve.

A travel-time curve provides the relationship between distance, P-wave, and S-wave arrival times.

Find the corresponding distance based on the obtained lag time.

Step 4: Calculate the Wave Amplitude

Measure the maximum amplitude of each wave recorded on the seismogram.

This step is crucial for both Richter and Moment magnitude calculations.

Ensure accuracy in reading the seismogram to avoid significant errors.

Step 5: Apply the Magnitude Formula

Use the appropriate formula depending on the scale you’re employing:
