How does faulting occur under the sea?

Faulting under the sea occurs due to tectonic plate movements, where stress builds up along fractures in the Earth's crust. When this stress exceeds the strength of the rocks, it results in a sudden release of energy, causing an earthquake. This process can create underwater faults and can lead to the formation of features such as ridges, trenches, or seafloor spreading zones. The movement can also trigger tsunamis if the seafloor displacement is significant.
