Earthquake Alaska recent

The quake had a depth of 71 miles, according to seismologists.

The town of Adak evacuated its 150 residents to a shelter about 600 feet above sea level after the initial tsunami warning, City Manager Layton Lockett told CNN.

There were no initial reports of quake damage in Adak or on Shemya Island, said Ian Dickson, website manager for the Alaska Earthquake Information Center.

Dickson said there were 17 measurable aftershocks in the two hours after the quake.

First estimates put the quake at magnitude 8.0. The strength was subsequently set by the U.S. Geological Survey at 7.9 magnitude.

Not necessarily. When two black holes collide they create an enormous gravitational shockwave that can, itself, spawn rogue (traveling) black holes. We are aware of a few, including one that has mass of about 600 million solar masses and is traveling at a speed of about 6 million MPH (relative to us). However, we have no idea how many of these wandering monsters are out there. And one wouldn't even need to hit us; if it merely wandered by the edge of our solar system, it would upset the orbits of the planets which would pretty much rip our solar system apart.
