The oldest oceanic crust is about 260 million years old. It is due to the process of subduction; oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges. It gets so dense, that it sinks in the upper mantle (subduction).
Answer:
Commonly yes, because sea floors tend to go under or up when a earthquake occurs.
