| Description: | Research Report Summary: A detailed seismic reflection survey was carried out at Site 2, Greenland in 1956 in a rectangle 3160 x 2400 ft, marked by bamboo poles, and was repeated in 1959. The results were essentially the same, indicating that the surface had not moved much in the 3-yr period. However, the reflection records were not of sufficiently high quality to give an accurate estimate of the possible shift, leaving an uncertainty of the order of 50 to 100 m in the direction of the subsurface dip (SW) and more in the direction of the strike. Under more favorable conditions the method should give an estimated accuracy of 30 to 50 m. |
