Why do many earthquakes but few volcanic eruptions occur in the Himalaya?

Answer 1

There are four type of tectonic boundaries. The first is the subduction which form volcano chains like the ring of fire. The second is divergent boundaries like the mid-Atlantic ridge. At the boundary there is volcanic activity and earthquakes as new crust is produced. There is also transform boundary which sliding along each other. Lastly there is the continental-continental convergent zone. That is what is a happening in the Himalayas. The continental crust is so light it can't be pushed down under the other continental and melt to create volcanoes. Instead it smashes into each other. The two continents create an area called a suture. The formation of the suture zone cause the earthquakes.

Answer 2

Because the collision of the Indian Plate and the Eurasion plate is not a subduction zone. These two land masses are pressing against each other and the land buckles, pushing up mountains. Volcanoes result from a subduction zone where one land mass goes over top of an ocean plate, such as the west coast of North America moving over the Pacific Ocean.

Answer 3

The Himalayan Mountains are not volcanic in origin, and are perhaps too high for any magma to work itself up through any cracks in the tectonic plates. The Rocky Mountains in North America are similar, but the Coast Mountains (Mount St. Helens, for example) are volcanic.

Answer 4

Because the Himalaya's are the result of collision of the India subcontinent and the Asian continent rather than subduction of one plate under another where the submerging material melts and proceeds up through cracks in the overriding plate.
