Recorded USGS earthquakes from the last 7 days, magnitude 2.5 and larger, within 250 km of Prudhoe Bay / Deadhorse. The dashed pale circle is a true 250 km radius around Prudhoe Bay / Deadhorse; amber rings are the recorded epicenters, sized by magnitude; small cream squares are the other towns, and the ringed cream marker is Prudhoe Bay / Deadhorse. If the USGS feed does not answer, the coastline, ring, and marker still show — and no events are plotted.

The biggest on record near Prudhoe Bay / Deadhorse — USGS catalog, as recorded

The five largest earthquakes recorded within 200 km of Prudhoe Bay / Deadhorse since 1900, from USGS catalog pulls made November 8, 2026. Pre-instrumental magnitudes are estimates, and catalog completeness varies by era — the fine print is on the about page.

How often does the ground move here?

89 earthquakes of M4.0 or larger were recorded within 200 km in the last 10 years — most of them in a single month, the August 2018 Kaktovik sequence, not a steady rate. The full catalog since 1900 holds 124 such events.

Prudhoe Bay's recorded history is dominated by one sequence: the August 2018 Kaktovik earthquakes, an M6.4 and M6.0 east of the bay — the largest North Slope events in the modern record — in a region otherwise as sparse as the rest of the Arctic, where few instruments listen and the small events go uncounted.

Arctic Alaska — why it shakes

The Arctic Slope and Brooks Range sit far from the plate boundary, and their earthquakes are the state's sparsest — intraplate adjustments in old, cold crust, plus a known active zone near the Mackenzie Delta just across the Canadian border. With few seismometers and fewer people, the catalog here is thin by construction: events under about M4.5 have often gone unrecorded, especially before the modern network.

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.
