The following corrections were brought to us by a one Poul Jensen--a Danish space physicist extraordinaire.  He's cool.  :) Poul is very good at correcting us "sloppy Americans," 'n stuff.  :)

>First, all sources I have read mention the distance from Fairbanks to

>Second, it is not the second largest earthquake recorded in North


>Rather, it would most probably be somewhere between number 10 and 20. I

>in the US having ML7.9 or larger can be found at


>And to those can be added eventual earthquakes in North America outside

>the US - I know there was an ML8.0 earthquake in Mexico in 1995.

>That said, we certainly should feel lucky (those of us who like such

-Snippage---for Poul's sake.  :)

>Though we do have

>"This M7.9 shock is the largest earthquake on the Denali fault since at

>the fault, more than 50 miles to the east of today's epicenter. Since

>there was only one seismographs operating in Alaska at that time and no

>reports of surface faulting in the remote Alaska Range, the location of

>the 1912 shock is not well-constrained. The modern fault scarp is very

>clear, but somewhat degraded, indicating that there has been at least

>several hundred years since last major earthquake(s) between McKinley

>Park on the west and the Richardson Highway on the east. In epicentral

>area, USGS geologist George Plafker observed that the last big

>earthquake had 6-8 m of right-lateral offset. Slip rate on the Denali

>fault since the last glaciation (10,000 years before present) averages

>about 1 cm/year. It follows that a 6-m displacement would require 600

>years of strain accumulation."

>So even though we were not within 80 miles from the second largest
