It seems to me, for the past year or so, many of the world's earthquakes are first reported to be very strong then shortly after "updated" to a MUCH smaller strength. Today's example: M6.9 - RAT ISLANDS, ALEUTIAN ISLANDS, ALASKA to M5.7 - RAT ISLANDS, ALEUTIAN ISLANDS, ALASKA
These numbers are VERY different, so I'm curious as to how they can be so far off on the initial reading.
From Wiki: "Thus an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times greater than that of an earthquake that registered 4.0 and thus corresponds to a release of energy 31.6 times greater than that released by the lesser earthquake." http://en.wikipedia.org/wiki/Richter_magnitude_scale

I have the "Earthquake Alert" app on my phone.
There was a Tsunami advisory issued after a 7.9 quake near Little Sitkin Island, Alaska at 1:53pm PDT today. Then several after shocks at 3.8, 6.0, 3.7, 5.9, etc.,etc., etc. There have been numerous in the last few hours.

Which was reduced from 8.0 which is close and understandable. I just have noticed in the last year or so, many of the world's quakes are drastically reduced in strength a short time later and referred as to "updated."

I watched the usgs site a lot until they changed the format. I liked the map they had , now it is a bit of a protracted effort to get to one.

I would have to trust Fox news on this.
