Final answer:
Arrange the seismic stations in order from closest to farthest based on their P-S intervals.
Step-by-step explanation:
To determine the order of the seismic stations from the closest to the farthest away from the earthquake, we need to arrange the stations based on their P-S intervals. The P-S interval represents the time delay between the arrival of the P-wave and the S-wave at each station. The station with the smallest P-S interval will be the closest to the earthquake, while the station with the largest P-S interval will be the farthest away.
Given the P-S intervals:
DUG = 57 sec
WUAZ = 73 sec
ISCO = 14 sec
Arranging the stations in order from closest to farthest:
- ISCO (14 sec)
- DUG (57 sec)
- WUAZ (73 sec)
