I was just fooling around at the usgs site and did a edit search for 'rat' on their latest eq listing. Man, that place is shakin'! Lots of 2's, 3's and 4's. Its sure know wonder that the 'most dangerous catch' fisherman are hit with rogue waves like crazy. That and collapsing selves, perhaps together, like a chicken and an egg.
Any Rogue Waves in the Bering Sea have nothing to do with seismicity.
Actually the Rogue Wave capital of the world is the strait between South Africa and Madagascar.
It's just that the Rat Islands have enough seismic monitoring to pick up everything (and the USGS site shows smaller quakes within the US than elsewhere in the world) but not quite enough to get a really accurate quick magnitude.
What you saw was an automated computer program coming up with the 7.1, which was in error; after a human reviewed it it was dropped to 6.0.
The Rat Islands aren't in one of the seismic "gaps" within the Aleutians that are likely to generate a magnitude 8-9 quake in the near future; there was one posited further East (The Shumagin Gap) but some new evidence suggests that area just doesn't slip in big earthquakes. There's the "Commander Gap" at the extreme west end of the Aleutians where such a large quake may be possible.
