Seismic Hazard Profile

About Earthquake Activity in United States

The United States possesses a diverse and highly active seismic footprint, primarily concentrated along the Pacific Rim in Alaska, California, Washington, Oregon, Hawaii, and Nevada, with additional intraplate seismic zones in the Central and Eastern US like the New Madrid Seismic Zone. The USGS operates thousands of real-time monitoring sensors across the country.

Why does United States experience earthquakes?

Seismicity in the US is governed by multiple tectonic regimes. The western margin features the Cascadia Subduction Zone in the Pacific Northwest (where the Juan de Fuca Plate dives beneath North America), the 1,200-kilometer San Andreas transform fault in California, and active crustal extension across the Basin and Range province. Alaska is shaped by rapid subduction of the Pacific Plate beneath the Aleutian Arc, while Hawaii experiences volcanically driven seismicity over a mantle hotspot. In the continental interior, ancient re-activated rift zones periodically generate powerful intraplate earthquakes.

Frequently Asked Questions About Earthquakes in United States

Expert answers to common questions about seismic risks, fault lines, and earthquake activity in United States.

The live US feed above displays all earthquakes recorded across the 50 states and territories within the past 24 hours, including seismic hot zones in Alaska, California, Hawaii, Nevada, and the Pacific Northwest.

Alaska records the highest volume and strongest earthquakes in the US, accounting for more than half of all magnitude 5+ US quakes. California ranks second in total frequency, followed by Hawaii, Nevada, and Washington.

ShakeAlert is an automated earthquake early warning network developed by the USGS and partner universities in California, Oregon, and Washington. It analyzes sensor data in real time and pushes alerts to cell phones via Wireless Emergency Alerts (WEA) and apps like MyShake.

Located in the central US (touching Missouri, Arkansas, Tennessee, Kentucky, and Illinois), the New Madrid Seismic Zone produced massive M7.5+ earthquakes in 1811-1812. Because the central US crust is colder and denser than the west, seismic waves travel much farther and shake far larger surface areas.
