If you're asking, is the quake on the Carlsberg Ridge related to the Nepal quake? Nothing wrong with questions. It's how we learn.

But really, no relation. It's over 2,000 miles away.

The Carlsberg ridge is a spreading center where the crust pulls apart and mantle magma wells up to form new crust. Quakes like this are pretty typical of mid ocean ridges. They can get quite big, too, especially along all the transform faults that break up the ridge line.

The Nepal quake, and the Himalaya in general, are on the other side of the Indian Plate. The tectonics there are cause by the subduction of the plate. It's a whole different ball game.

The quake you ask about would be on the ridge in the center of the diagram, whereas the Nepal quakes and Himalaya are on either of the trenches off to the side - on the other side of the tectonic plate they are on.
