Abstract:
Due to the low seismicity of the Charlie-Gibbs Fracture Zone it has not been possible to examine in the past. Now there is over 50 years of seismic data to reexamine the fracture zone and past-hypothesized relationships, such as an inactive southern trough of the fracture zone. The results indicate the southern trough of the fracture zone still appears to be inactive and the fracture zone has reached a full seismic time cycle. It is postulated that the southern troughs inactive behavior is from a low velocity, low viscosity zone from unusually thin crust (3.0-4.5 km).
