Arrival Time Picks from Trans-Alaska Crustal Transect 
Explosions

The southern Alaska regional seismograph network recorded 
explosions detonated in the U.S Geological Survey?s Trans-
Alaska Crustal Transect. In the summers of 1984 and 1985, 
fifty-five explosions (table of locations and sizes, PDF or 
Excel) were detonated south of the Alaska Range to 
investigate crustal structure along seismic refraction 
lines parallel and perpendicular to the trans-Alaska oil 
pipeline corridor (map from Fuis and others, 1991). Phases 
from 52 explosions were picked and timed, primarily from 1-
inch-per-second, oscillographic paper records obtained from 
analog magnetic-tape recordings of signals from network 
stations.
