Abstract

In this study, Landsat Multispectral Scanner (MSS), SPOT satellite, and airborne C-band synthetic aperture radar (SAR) images are processed, integrated, and interpreted for regional tectonic feature interpretation including the study of surface geological and topographical features. The final composite image clearly shows the 1985 landslides caused by the two large earthquakes hear the North Nahanni River, NWT, Canada. The final C-SAR/SPOT image overlaid with main shock and aftershock epicenter information appears to reveal a new N-S trending tectonic feature which meets the Iverson thrust fault at the southernmost portion of Boom Creek. This coincides with the southern end of the main shock and aftershock epicenter cluster in the area. There is apparently an E-W trending structure which follows along the North Nahanni River west of the Iverson Range. This feature extends towards the east outside of the C-SAR/SPOT composite image and appears to continue in an east-southeasternly direction towards the MacKenzie River.
