Figure 6.17 Star indicates the 2001 Bhuj earthquake. Local uplifts estimated from interferogram
fringes of DInSAR data are shown north of the epicenter. ENVISAT data between two dates 1.5 yr
apart (June 22, 2008-October 25, 2009) have been used. North of the epicenter the interferogram
fringes were identifiable in hilly uplifted areas only, not in large low-lying areas. South of the
epicenter around the KMF and KHF, ENVISAT data were used during 2004-7 and ALOS data,
2007-10 (modified after Choudhury
et al
.,
2012
)
. Deformation could be measured for time intervals
of
1yr.
