Mendocino Triple Junction

Petrolia is located near the Mendocino Triple Junction, where three fault lines meet and experiences frequent earthquake activity.

This seismically active intersection is called a triple junction, and specifically the Mendocino Triple Junction.

Where the three intersect is the seismically active, F-F-T Mendocino Triple Junction.

The Mendocino Triple Junction is to the west of Cape Mendocino under the Pacific Ocean.

The triple junction is often referenced as the southern counterpart of the Mendocino Triple Junction, but it is not as well understood.

North of Rockport, the highway turns away from the Lost Coast to avoid steep and unstable highlands created by Mendocino Triple Junction uplift.

Offshore of Cape Mendocino lies the Mendocino Triple Junction, a geologic triple junction where three tectonic plates come together.

After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.

They consisted of a 7.2-magnitude main shock and two strong aftershocks that spawned a series of smaller aftershocks that ranged in magnitude from 4.0 to 4.8, associated with the Mendocino Triple Junction.

To the south, just off of Cape Mendocino in California, it intersects the San Andreas Fault and the Mendocino fault zone at the Mendocino Triple Junction.

The Lost Coast consists of undivided Cretaceous marine metasedimentary and sedimentary rocks of the North American Plate steeply uplifted by Mendocino Triple Junction interactions with the Pacific Plate and Gorda Plate.

The King Range is adjacent to the Mendocino Triple Junction, where three tectonic plates (the Pacific Plate, the North American Plate, and the Juan de Fuca Plate) meet, and the area experiences frequent earthquakes.

Part of the problem in describing the Rivera Triple Junction is that if it were truly analogous to the Mendocino Triple Junction, then it would exist at the junction of the East Pacific Rise, the Tamayo Fault, and the Middle America Trench.

The Mendocino Triple Junction is a geologic triple junction where the San Andreas Fault meets the Mendocino Fault and the Cascadia subduction zone, separating three tectonic plates: the Pacific Plate, the North American Plate and the Gorda Plate.
