Electronic Supplement to Seismic Velocity Models for the Denali Fault Zone Along the Richardson Highway, Alaska

by Thomas M. Brocher, Gary S. Fuis, William J. Lutter, Nikolas I. Christensen, and Natalia A. Ratchkovski

Notes: The following tables provide locations for the TACT 1986 and TACT 1987 lines.  Table 1 summarizes the VP number locations and elevations, and model distances and elevations for the Brocher et al. (1991) model. Locations of streams and other local landmarks along the model are noted in Table 1.  Coordinates for these VP locations were picked from a 1:50,000 scale digital topographic map, and are accurate to within 100 m. Model elevations shown in Table 1 correspond to elevations used by Brocher et al. (1991).

For Tables 2 and 3 the shot and receiver locations, from 1:63,000 scale USGS topographic maps, are accurate to about 20 m (Beaudoin et al., 1989).

Note: Nonbold Vibrator Point (VP) numbers indicates VP was located from field map showing VP flag numbers. Bold indicates VP calculated from model distance along line, using a VP interval of 30 m.

Table 2. TACT 1987 Shotpoint Locations, Elevations, Sizes, Hole Geology, and Origin Times

Note 1: Borehole depths, except for longest holes, were calculated from a linear charge density of 34 kg/m of hole length and assumed a 15.3 m long tamp.

Note 2: SP 43 was a failed shot, yielding no useful information.
