Quick Facts: North American Earthquakes

Why North America Shakes — The Science Behind Its Earthquakes

North America isn’t exactly a calm continent as it’s one of the most geologically active regions on Earth, shaking tens of thousands of times each year. Most of those earthquakes are too small to feel, but the powerful forces behind them are constantly shaping mountain ranges, rivers, and coastlines across the U.S., Canada, Mexico, and Central America

A huge part of this activity happens along the Pacific Ring of Fire, a 40,000-kilometer, horseshoe-shaped zone circling the Pacific Ocean. It’s responsible for about 90% of the world’s earthquakes and roughly 75% of volcanic eruptions. The West Coast of North America, from Alaska and British Columbia down through California and Mexico, sits right on this fiery edge.

The continent rides on the North American Plate as it collides, grinds, and slides against the Pacific, Cocos, Caribbean, and Juan de Fuca Plates, producing everything from subduction megathrust earthquakes to deep intraplate tremors. New research suggests the Cascadia Subduction Zone and the San Andreas Fault may be dynamically linked, meaning a megaquake in one could influence the other.

California & The Pacific Northwest: North America’s Sleeping Giants

Running for about 1,200 kilometers, the San Andreas Fault marks where the Pacific Plate slides past the North American Plate at roughly 5 centimeters per year. In Southern California, more than 10,000 earthquakes are recorded every year, though most are too small to feel.

Further north, the Cascadia Subduction Zone can unleash magnitude 9.0+ megathrust earthquakes roughly every 300–600 years, with the last one striking in 1700. A 2025 Scientific American study warns the next Cascadia event could trigger stress along the San Andreas, and NOVA PBS modeling shows coastal land could sink up to 2 meters, doubling flood exposure in parts of the Pacific Northwest.

Alaska: The Seismic Giant

Alaska experiences around 40,000 earthquakes per year. Along the Aleutian Trench, the Pacific Plate dives beneath the North American Plate at up to 7 cm per year, creating the world’s longest volcanic island chain.

Three of the ten largest earthquakes in history have struck here, including the 1964 M9.2 Great Alaska Earthquake. In July 2025, a M7.3 near Sand Point generated over 2,700 aftershocks in a single month. New seismic early-warning systems under test aim to provide up to two minutes of advance notice.

Hawaii: The Hotspot Exception

Unlike most of North America, Hawaii’s earthquakes are driven by volcanic and gravitational processes. As the Pacific Plate drifts northwest over a stationary hotspot at 7–10 cm per year, magma intrusions and volcanic flank movements trigger frequent quakes.

On the Big Island’s south flank, the ground creeps a few centimeters toward the sea each year, and it can occasionally produce large events, like the 2018 M6.9 Kīlauea earthquake. Thousands of smaller tremors usually accompany each eruption, showing how tightly Hawaii’s seismicity is linked to active volcanism.

Mexico: Powerful Quakes from Coast to Capital

Along the Middle America Trench, the Cocos Plate plunges beneath the North American Plate at about 6–7 cm per year, driving frequent subduction earthquakes and volcanism. States like Guerrero and Oaxaca often find themselves near the epicenters of these shallow, destructive quakes.

Mexico City, though about 300 km inland, amplifies seismic waves because it sits on an ancient lakebed. This effect was clear during the 1985 and 2017 events, when soft sediments caused prolonged, intense shaking.

Caribbean Region: The Web of Faults

The Caribbean Plate interacts with the North American, South American, and Cocos plates across a network of faults and subduction zones. The Puerto Rico Trench, 8,400 meters deep, marks a subduction interface capable of M8.0+ earthquakes.

Strike-slip faults also matter: Haiti’s Enriquillo–Plantain Garden Fault caused the 2010 M7.0 earthquake. Research studies suggest regional stress transfer could raise seismic risks across Hispaniola and Puerto Rico.

Central America: The Constant Clash of Plates

Central America sits on one of Earth’s most active subduction zones, where the Cocos Plate dives beneath the Caribbean Plate. This collision regularly produces moderate to major earthquakes and fuels a chain of active volcanoes from Guatemala to Panama.

Countries like Guatemala, Nicaragua, and Costa Rica often bear the brunt, with shaking that can trigger landslides and, along the coast, tsunamis.

Canada & the U.S. Interior: Quiet but Not Inactive

Much of Canada and the central/eastern U.S. lies far from plate boundaries, but intraplate earthquakes still occur as ancient faults reactivate. In eastern Canada, the Charlevoix and Western Quebec zones see periodic tremors. In the U.S., the New Madrid Seismic Zone remains a concern. The 1811–1812 events even briefly reversed the Mississippi’s flow.

Greenland & the Arctic: Low-Frequency but Not Zero

Although seismic activity across Greenland and the high Arctic is far lower than along plate-boundary regions, it remains scientifically important. Greenland rests on a stable section of the North American Plate, with most earthquakes below magnitude 6, and clustering along the island’s northeastern and eastern coasts. These quakes are mainly caused by the slow reactivation of ancient fault zones and the glacial rebound that occurs as the crust adjusts to the ongoing melting of the ice sheet.

Recent studies have also detected rare, ultra-low-frequency seismic waves linked to massive landslides and fjord-generated tsunamis in East Greenland, events powerful enough to send global vibrations picked up by seismic sensors around the world.
