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.
