Figure DisMH depicts the displacement at the mean hypocentre of the earthquakes in the longitude band 80-100 for each hydrological year between 1 June 1973 to 31 May 2008 and from 1 June 2008 to the last data as of 15th September 2008. Notice the massive 570m subsidence for 2003-04 caused by the 26th December 2004 Andaman Sumatra Great Earthquake of 9.1-9.3 MM and the subsidence persisted at 74 m till 15th September 2008 at the mean hypocentre(16,93.28) when the last data was obtained for this study. Thus the eastward slope in the Kosi basin in particular and of probably of the subcontinent itself as a whole happened from this date. The catastrophe of the massive 120 km shift eastward of Kosi was waiting to happen since! The massive subsidence initiated by the 20th February 2008 7.5MM Major Earthquake at its hypocentre at (2.77,95.96,26km), the 25th February 2008 7.3MM major quake at its hypocentre at (-2.47,99.97,25km) ,20th March 2008 7.2 MM Xinjiang-Xizang Border major earthquake at hypocentre (35.49,81.47,12km), 12th May 2008 Sichuan Earthquake at hypocentre (31,103,10km) and the uplift caused by the 5th August 2008
6 MM earthquake also at almost the same location as the Sichuan quake:
The team is outraged to report that the government's investment
of over Rs 1600 crores since the early 1950's has helped increase the
flood prone area from 25 lakh hectare during the pre-plan era to over
68.8 lakh hectare today, an unprecedented three-fold increase.
Proposed as temporary measure to control floods in the 1950s and
having had failed on all fronts, the team is bewildered to note that
the business of embankment construction has resumed after a lapse of
17 years with a Rs 792 crores package to tame the Bagmati. There is
another proposal to embank the tributaries of Mahananda at an
estimated cost of Rs 850 crores. Clearly, the lessons in human misery
have not been learnt.
The India subcontinent dams are the cause of the catastrophic effect of the shifts in hypocenters in the two longitude bands 60-80 and 80-100 from the pre-dam era to the dam era. This is because whenever an earthquake occurs, the full force of the cumulative archimedean lever effect of the changes in the contents of all the dams is applied at this one hypocentre. The effect is a massive reversal in tilt between the pre-dam and dam eras between the two longitude bands and consequent unprecedented three times increase in the flood prone area from the pre-dam era to the dam era on the subcontinent. See Table EDTF. See also the massive difference in the displacements of the hypocentres during the dam era in the two longitude bands(Fig ST7308):
