Aftershocks continue in Interior
FAIRBANKS - Alaska has been averaging more than 100 earthquakes a day along the Denali Fault since a magnitude 7.9 earthquake rocked the Interior on Nov. 3.
The Alaska Earthquake Information Center in Fairbanks has documented more than 4,300 aftershocks of the big quake, which shook Fairbanks and ripped up roads throughout Interior Alaska.
"With a rupture length of 270 kilometers, we expect thousands of aftershocks," said seismologist Natasha Ratchkovski.
While most of the aftershocks have had magnitudes of 2.0 to 4.0, there have been more than 125 aftershocks with a magnitude of 4.0 or greater. The largest aftershock recorded was a magnitude 5.8 about 20 minutes after the main quake. All the aftershocks have been along the 400-plus mile Denali Fault.
