27.3.1. Wave Arrival Identification

Try these first

1. 1.

   What wave arrives first during an earthquake?

   Hint

   Think about the wave that is known as the primary wave.

2. 2.

   Name one characteristic of S-waves.

   Hint

   Consider what makes them different in terms of energy.

3. 3.

   Which type of wave arrives first during an earthquake?

   • P-wave
   • S-wave
   • Surface Wave

   Hint

   It's called the primary wave.

4. 4.

   True or False: S-waves travel faster than P-waves.

   • True
   • False

   Hint

   Remember the sequence of arrival.

5. 5.

   Given a seismogram that displays the arrival times of P, S, and surface waves, analyze how this information can be used to assess the earthquake's epicenter location.

   Hint

   Reflect on how the differences in wave speeds aid in determining distances.

6. 6.

   Consider a building designed to withstand earthquakes. How would understanding the difference in wave types help in its design?

   Hint

   Think about how each wave's characteristics influence building resilience.
