This is strange. We use the Alaska Earthquake Information Center every day to see if there’s been any new quakes and I just pulled up their website and they are not showing a quake of this magnitude.
They’re showing:
09:09 PM AKDT Wednesday August 1st, 2007 1.69 ML in the Andreanof Islands region of Alaska
08:08 PM AKDT Wednesday August 1st, 2007 4.59 ML in the Andreanof Islands region of Alaska
06:03 PM AKDT Wednesday August 1st, 2007 2.07 ML in the Andreanof Islands region of Alaska
