Summary: | Neotectonics may be defined as any recent movement or deformation at or near the earth's surface, and the associated geological processes or mechanisms thereof (Vita-Finzi 1986). A regional study of large landslides was undertaken in southwest Yukon, with the aim of assessing the relationship between large landslides and neotectonic processes, with particular emphasis on the role of seismicity. Landslides were inventoried in an area covering 18,800 km² in southwest Yukon and 4,400 km² in adjacent south-eastern Alaska. Their spatial distribution was found to correlate with certain lithological units, regional faults, and often dense clusters of low-level earthquakes. Seismicity is especially intense in the Cement Creek area, where the relative temporal distribution of landslides departs from the regional slope exhaustion model and more closely resembles a steady-state distribution. A recent (1983) landslide in this area was attributed to a modest M5.4 earthquake (Power 1988). Field reconnaissance in Cement ... |
