**Seismograms**

Figure 1 is a simplified example of a seismogram. The vertical lines, spaced one minute apart, represent the passage of time (from left to right). As the drum rotated, the pen recorded the arrival of P, S, and surface waves from a distant earthquake. The time between arrival of P and S waves is called "lag time." The farther a station is from the epicenter, the longer the lag time measured at that station. Note the differences in velocity, amplitude, and frequency of the different types of seismic waves.

**Diagram Explanation**

- The diagram shows a cylindrical seismogram printout with marked lines for "First P wave," "First S wave," and "Surface waves."
- Vertical lines indicate time intervals, set one minute apart.
- The waves are labeled as P (primary), S (secondary), and surface waves, each exhibiting different characteristics:
- **P Waves**: Arrive first, with smaller amplitude.
- **S Waves**: Arrive after P waves, with larger amplitude.
- **Surface Waves**: Arrive last, showing the largest amplitude and greater complexity.
- An arrow labeled "TIME" indicates the direction of time progression from earlier to later.
- Differences in wave characteristics highlight variations in their velocity, amplitude, and frequency.
