Quick Summary

An aseismic ridge is a long, mountainous structure found on the ocean floor that is not associated with earthquakes. These ridges are typically formed by volcanism from a hot spot, creating a series of volcanoes.1

The Hawaiian Ridge is a prime example of an aseismic ridge in the Pacific Ocean. It stretches from Hawaii westward to the 180° meridian and is part of the larger Hawaiian-Emperor chain, which is the most extensive aseismic ridge on Earth. While earthquakes occur at the active volcanic end of the Hawaiian Ridge on the island of Hawaii, the ridge itself is characterized by its lack of seismic activity. Other notable aseismic ridges exist in the Indian and Atlantic Oceans.12
