A REFRACTION PROFILE FROM HATCHER PASS TO SEWARD, SOUTH CENTRAL ALASKA
This small project, which involved coordination among several agencies, was initiated to take advantage of blasting on a highway project near Anchorage. The blasts were large enough to obtain meaningful seismic profile data in an area where no data had been obtained since the 1964 earthquake. The quick response of several research groups allowed instrumentation to be fielded and data was obtained. This project provided an additional data base in the re-evaluation of the "L" Street slide area in Anchorage, an area that is still being studied 20 years after the 1964 earthquake to determine if it is safe to build large office structures. The project also led to the concept of using seismic methods to prospect for suitable rip-rap sources in the Homer area. (Author)
