Aseismic ridge
An aseismic ridge is "a long, linear and mountainous structure that crosses the basin floor of some oceans." They do not cause earthquakes.[1]
It is called an "aseismic ridge" because they do not receive seismic activity. As a result, they tend to be stable. They are 700–5,000 kilometers (430–3,110 mi) in length.[2]
Aseismic ridges going towards subduction zones can impact the process of subduction, causing a phenomenon known as flat slab subduction.[3]
