Geophysicist Roger Bilham has said Himalayas the only place in the world where a large quake can occur on land
- In both C-C convergence and C-O convergence, there is the formation of fold mountains and frequent occurrence of earthquakes.
- This is because of the sudden release of friction between the subducting plate and up thrust plate.
- In C-C convergence, the denser plate pushes into the less dense plate creating a fault zone along the margin.
- Further collision leads to the sudden release of energy along this fault zone generating disastrous earthquakes (shallow-focus earthquakes).
- Volcanism is observed only in C-O convergence and is almost absent in C-C convergence.
