Walvis Ridge
aseismic ridge, Atlantic Ocean
Quick Summary
The Walvis Ridge is a long, mountainous underwater structure in the Atlantic Ocean that is not associated with earthquakes. It was formed by volcanism from a hot spot, likely originating from the same volcanic activity that created Tristan da Cunha. This ridge trends northeast from that location towards the African coast. Unlike oceanic spreading centers, aseismic ridges are characterized by a lack of seismic activity within them.1
