Question

Sonic Boom South America earthquake P wave and U.S. Navy fighter sonic boom - Nevada 1988 - u.s Nrica We can visually analyze the 6. recorded seismograms to identify waves with different frequency content. Occasionally, this visual analysis can immedately tell us that the recorded waves have different sources of Earthquake P-wave vibrations, as is the case in Fig. 4. This figure shows a recording of waves from both, a sonic boom and an earthquake. Which has higher frequency content, the sonic boom or the earthquake? How do you know this? O 5 10 15 20 25 30 35 Time (s) Fig.4

Answer 1

Sonic boom has higher frequency content. Wave maximas and minimas are closely spaced together with time hence higher frequency.
