Fault Name Index

Galway Lake Fault

Type of Faulting: right-lateral strike-slip
Length: about 7 km
Nearest Communities: none within 20 km
Last Surface Ruptures: May 31, 1975, ML 5.0, and June 28, 1992, MW 7.3
Slip Rate: 0.5 mm/yr or less (?)
Interval Between Major Ruptures: 2000 years (?)
Probable Magnitudes: ML 5.0 - 6.0
Other Notes: Data given above is for rupture of Galway Lake Fault alone.

 

Unknown until its first historic rupture in 1975, the Galway Lake fault is connected at its southern end to the Emerson fault, and has shown in recent years its ability to rupture separately or in concert with other faults, as during the Landers earthquake of 1992. It has been suggested that the Galway Lake fault and other smaller faults first noticed after the Landers quake may represent a connecting fault zone in formation, to ultimately link the Emerson-Camp Rock fault system with the Calico and West Calico faults.
