An earthquake epicenter is 4600 kilometers from a location. If the p-wave arrives at 3:00:20, what time will the s-wave arrive?

Surface waves, S waves, and P waves can all be recorded by a single seismogram. However, they show up separately on the seismograph because they travel with different speeds.

Look at the seismograph below, and identify the surface wave, the S wave, and the P wave.

Drag the appropriate labels to their respective targets.

1. P wave

2. S wave

3. Surface wave

The S wave arrives 3 minutes after the P wave, so the epicenter is approximatelymiles away.

1250

The S wave arrives 1 minute after the P wave, so the epicenter is approximately miles away.

250

The S wave arrives 5.5 minutes after the P wave, so the epicenter is approximately miles away.

2500

Drag the appropriate items into their respective bins. Each item may be used only once.

Hint 1. Epicenter distance

The distance in miles of the epicenter is shown on the map. It is also the horizontal axis on the graph.
