The Mw 7.6, Kashmir Earthquake of October 8, 2005

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

The Mw 7.6, Kashmir Earthquake of October 8, 2005 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 5 m

Amplitude of Horizontal slip Horizontal fault slip vectors 2m

Estimated Rupture Area of major Himalayan earthquakes

According to GPS measurements and microseismic monitoring the Main Himalaya Thrust fault is locked over a width of km (yellow aera).The Accumulation rate of deficit of seismic moment is estimated 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) ?
