Comments
This fault was added in the 2007 maps. The short trace (13 km) of the fault is partly obscured by eolian sand and is rapidly being destroyed by development in suburban Albuquerque. Three surface ruptures resulting in 2.75?0.1 m offset of a 286?26-ka eolian sand (Personius and Mahan, 2000) suggests a vertical slip rate of 0.0096 mm/yr.
