How often does the ground move here?
31 earthquakes of M4.0 or larger were recorded within 200 km in the last 10 years — a busy rate by Alaska standards. Since 1900 the catalog holds 345 M4-or-larger events within the same radius.
Delta Junction sits near the eastern end of the Denali fault's 2002 rupture — the M7.9 of November 3, 2002 broke the ground along the fault not far northwest of town, the largest inland Alaska earthquake in the instrumental record.
Interior Alaska — why it shakes
The Interior shakes on its own terms. North of the Alaska Range, a set of long left-slipping faults — the Denali, Totschunda, and their neighbors — grind past each other as crust caught between the subducting Pacific Plate and the rotating Yakutat block squeezes northward. Interior earthquakes are mostly shallow crustal breaks, and the region's clusters near Fairbanks, Minto Flats, and the Tanana Valley can run for months after a larger event.
New to the numbers? What magnitude means explains the scale in plain words — including why a whole step is about 32 times the energy, and why what people feel is not the same as damage.
