What is it about?
The densely populated country of Nepal sits above the Himalayan Frontal Thrust fault. It is repeated displacements on this fault that are responsible for the uplift of the Himalaya mountains and considered capable of producing great earthquakes. Here we excavate a trench across the fault to show a great earthquake occurred 1146 -1256 AD in eastern Nepal. It has been a sufficiently long time since then that stresses have accumulated to a level capable of producing another such great earthquake.

Why is it important?
• Additional limits placed on potential length and location of future large earthquakes along the Himalayan Frontal Thrust • Dip-slip displacement of ~11 m on Himalayan Frontal Thrust (HFT) in eastern Nepal occurred roughly 800 years ago in 1146–1256 A.D. • Slip now accumulated along Main Himalayan Thrust (MHT) of eastern Nepal to produce another earthquake similar to event of ~800 years ag
Perspectives
This paper is important because it highlights the earthquake history in eastern Nepal.
