Answer:
ISCO-DUG-WUAZ
Explanation:
Seismic waves of an earthquakes is recorded first in the station closest to the earthquake. The P wave is the faster moving wave and then the S wave. The faster the time it takes the P and S waves to register in the seismographer the closer the station to the site of the earthquake. Bearing this in mind, the wave was first registered in ISCO making it closest to the earthquake site, followed by DUG and then WAUZ.
ISCO (14sec)-DUG (57sec)-WUAZ (73sec)
