According to the news, the current Indian landmass was once part of ______ milli

Geologists say they knew that a large earthquake was coming in South Asia, but they did not know when.
   The Himalayan Mountains were formed some 150 million years ago after the landmass that is now India broke off from Antarctica, drifted north and collided with the rest of Asia.
   Scientists say the South Asian land mass is still moving towards North Asia at the rate of about two centimeters a year, making the area prone to earthquakes.
   Harley Benz is a researcher at the U.S. Geological Survey earthquake information center. "It’s a broad zone of deformation, and across this zone that extends 1,000 kilometers, you have a whole series of faults and folds."
   Another earthquake-prone region is along the 1300 kilometer San Andreas Fault in California.
   It is here that John Rundle, a physics and engineering professor at the University of California at Davis, is testing his earthquake computer simulation.
