Maybe I can help you .First you need to know every day many collosion of ocenaic plates occur in the Earth's ocean .Collosion has different levels, some are small, and some are big .The high levels we can call them earthquake . lf we say collision of ocenaic can cause tsunami , then we will face tsunami everg day .In general, smaller collision of ocenaic plates won't cause any damage .Only some big can cause such a big damaged .
I hope I can help you

collision of ocenaic plates => transforming faults' lateral shearing only.
most of them are expanding (drifting apart)
