Peer Review (Erik (talk))

Most of my modifications were for the sake of clarity.

Introduction:

- Do you know when Farrallon broke up and was fully subducted?

Boundaries:

- Your description of the Explorer Ridge and Winona Basin needs clearing up. I can't determine the relationship of these two features.

Formation and Evolution:

- The final sentence contains a lot of information and it is not clearly connected. You should break things up or else structure the sentence differently.

Current State of Subduction:

- Bullet (1) should be made more concise.

Seismic Activity:

- You mention that the seismicity is anomalous. I interpreted that you meant that earthquakes occur on the other boundaries of the plate, not the subduction zone. If this is incorrect, then you should modify my edits.

Planned additions (Daothao (talk))

The image featured obscures the plate by the seismology and I plan on using an editing a picture similar to other pages on tectonic plates such as Juan de Fuca Plate, Pacific Plate, etc. Source image:[1]

I also plan on adding 2-3 sections on:

Seismology:

I plan on moving the current main image here and citing Seismotectonics of the Explorer region, discussing their analysis and findings.

Also, Earthquake Report: Explorer plate is a blog post that is well referenced and includes personal data but I will be looking for similar alternatives.

Morphology and Bathymetry:

There are a number of sources that discuss the morphology of the Explorer plate using different methods such as:

Morphology of the Explorer–Juan de Fuca slab edge in northern Cascadia (using bathymetry)

Tectonic Evolution of the Explorer-Northern Juan de Fuca Region From 8 Ma to the Present (magnetic anomaly data, in conjunction with Sea Beam and SeaMARC II data)

Queen Charlotte Triple junction:

The triple junction seems to be a topic of specific interest and I'll be adding some information from these :

Explorer deformation zone: Evidence of a large shear zone and reorganization of the Pacific–Juan de Fuca–North American triple junction

Ephemeral plate tectonics at the Queen Charlotte triple junction

Specifically noting Explorer plate's contribution/effects, though I might just redirect it to Queen Charlotte Triple Junction page's section on the Explorer plate.

I'll also be including a reference similar to this:
