US study says quake may have wiped out Harappa: a summary of Manika Prasad's work which indicates that the Harappan civilization, which I mentioned here a few days ago, may have been wiped out by massive earthquakes.
Nobody really knows why the Harappan civilisation that thrived around 2500 BC suddenly disappeared. Many theories have been propounded till date which include sudden floods, drought and even the invasion of the region by Aryans. And now a team of geologists from the Stanford University in California believes that the real blame probably lies with the massive earthquakes that struck the region in the past.
