| | Quake: Gurvan Bulag Thrust Fault, Mongolia |
 | | The Gobi-Altay earthquake of December 4, 1957, in southern Mongolia, is one of the world's largest recorded intracontinental earthquakes, and one of four great earthquakes that have occurred in or near Mongolia this century (Baljinnyam et al., 1993) (Figure 1). |
 | | The ruptures associated with this event are well preserved due to the sparse population and cold, arid climate of Mongolia, and remain spectacular (Figure 2A, Figure 2B). |
 | | This work was recently revisited and expanded upon by Baljinnyam et al., 1993, who studied a number of the active faults in Mongolia, and by Kurushin et al., in press, who conducted exceptionally detailed field mapping along the Gobi-Altay ruptures. |
