[4] Its southernmost section joins a spreading ridge of the Gorda plate and the Cascadia subduction zone while the northern termination section joins the a thrust fault where the Yakutat terrane plows into the North American plate.

[4] A note to take into account, the 2012 temblor had a focal mechanism of thrust rather than strike-slip, like those observed along the fault.

[8] The Craig earthquake, on the other hand, was a near pure strike-slip event which was probably in response to stress transfer from the quake four months ago.

[8] Research found that the earthquake was a rare supershear event, and was the first of its kind to occur on an oceanic plate boundary.

Afterward, the rupture velocity exceeded the S-wave propagation speed of 3.8 km/s, reaching 7.0 km/s through the upper crust at its highest.

[12][13][14] A maximum intensity of V (Moderate) was felt in Craig, Hydaburg, Klawock and Hyder without damage,[1] but there were reports of items falling off shelves.

[17] Seiches up to 1.5 meters high were also recorded at Deer Lake, Alaska, north of Port Alexander.
