Just because there is an earthquake in the ocean doesn’t mean there will be a tsunami. That occurs if the edges of a fault move differently up or down, displacing some water and making a wave. The Earth may need to open a bit because it is growing and expanding After all it is estimated that about 2,000 tons of cosmic dust, mostly particles from the Sun and from space accumulate on Earth every day. Some water may fill into the opened crack, but a tsunami will not be created.
