A ravine ~15 miles (~ 24 km) deep on average opens up in the Himalayas. Do we survive?

A ravine the size of the Mediterranean in area and ~15 miles (~ 24 km) deep on average opens up over the course of a few days in the Himalayas.

A size comparison of the Mediterranean Sea to the U.S. to give a better idea of the scale to Americans like me:

This is roughly the shape of the ravine superimposed over the Himalayas:

The Earth's crust is about 20-30 miles (32-48 kilometres) thick on average for continental plates. I specifically chose the Himalayas because I want this scenario to not penetrate into the Earth's mantle from the initial opening itself.

The cause of such a disaster would be the direct result of an unnatural magical event.

Would such an event snuff out all life, let alone intelligent life? Do we survive?

EDIT: for claritication, the nature of the magical event is that the section of crust in question disappears. This would be unnatural in our world, which is the setting I provided.
