Transverse faulting and subduction. Changes in density of the plate will determine the location of thrust faulting at the subduction zone and create adjacent perpendicular shear forces and transverse faulting. At great depth close to the moho, remelted crust loses density and is forced diapiretically toward surface, volcanism occurs, creating Island arcs. ie Marianas system, Japan & trench Aleutians etc.
Be careful no to apply this principle to the Hawaii Islands I have quite a different explaination there which will require more geochemical and seismic study. Well OK I guess you can for now.. the rest of the geological word has jumped to the conclusion. But just think of what happens when you have a stone in your shoe!

One oceanic plate will force the other down under and cause it to be subducted. This will in turn result in an oceanic trench. Perhaps an earthquake or something since there will be a release of pressure.
When 2 oceanic plates meet they don't pile up like what happens when 2 continental plates collide, and the Himalayas was formed as a fold mountain when 2 continental plates collide. =D

FIrst of all, an earthquake (tsunami) doesn't have to occur... If this ever happens, it will occur slowly. Earth is made up with plates that are always moving because of convection currents of molten material moving in cycles below the crust. If two oceanic plants converge, the converging center will build up or sink in, which could suddenly cause a tsunami!!!!

Well, the density of two oceanic plates are the same, so if they meet I suppose they would go straight up like the mid atlantic ridge.

I assume you mean tectonic plates. It depends on which ones you mean. In some, one plate is moving under the other,pushing it up. With some they just grind together causing the occasional earthquake. Its fascinating. Do a google search on tectonic plates, to get diagrams. good luck

usually when the plates shift they create earth quakes or tidal waves but if they collided then a huge tidal wave could happen. because to bodies of water would collide and create a dip in the floor which causes waves. but that movie that had that huge wave through nyc and it took out a couple of states something like that would happen.

WITH THE TWO PLATES MEETING THIS GOING TO CAUSE SWEELL IN THE OCEAN LIKE A HUGE TIDAL WAVE WHICH WILL MOVE AT A VERY RAPED SEED MAYBE TOWARDS THE LAND ALL DEPENDS WHERE THIS ACTION TAKE PLACE

The Himalayas is an example. They will collide and pile up. The Himalayas are still getting taller, but it is believed that pretty much all of the energy of that collision is spent.

As far as I know, an earth quake will happen, which in turn result in tsunami. For example, tsunami that happened in December of 2004 in Asia (Thailand, etc.)

Does the word Tsunami ring a bell?!
