- •
The Litang fault system (LTFS) is located in eastern Tibet
- •
We studied horizontally offset moraine crests at Cuopu and a vertically offset fan at Maoya along the LTFS
- •
The horizontal rate along the N Cuopu fault is ~ 2 mm/yr from 5.3 Ma to 29 ka
- •
The vertical rate at Maoya is constant at ~ 0.6 mm/yr since 5-7 Ma
- •
Its high segmentation, dominantly normal kinematics and low slip-rate reduce the risk of M > 7.5 earthquakes along the LTFS
