N-S ground displacements measured from ASTER Images of October 27, 2005 and November 14, 2000

The Horizontal slip on the fault was about 5 m over a distance of about 70 km

According to GPS measurements and microseismic monitoring the Main Himalaya Thrust fault is locked over a width of 100-150km (yellow aera).The Accumulation rate of deficit of seismic moment is estimated 4.3 1019 Nm/yr , this is enough to drive a a Mw 7.6 (like the 2005 Kashmir EQ) earthquake every 7 years, or a Mw 8.2 (like the Bihar-Nepal earthqiake of 1934 every 100yr).
