The 2014 Aleutian Islands earthquake occurred on 23 June at 11:53 HDT (UTC-9) with a moment magnitude of 7.9 and a maximum Mercalli intensity of VIII (Severe).

The earthquake was initially reported as 8.0 Mw before it was downgraded to 7.9.

Based on the geometry of the slab, and the relative movement of the tectonic plates, the slip vector is likely to have been oblique down-dip towards the ESE.

The fault plane appears to be oblique, striking NW-SE and cutting steeply into the subducting slab.

[6] A small non-destructive tsunami was generated, with heights of 17 cm on Amchitka.
