Seismic Activity in Alaska
Alaska has more earthquakes than any other US state due to the Pacific Plate subducting beneath the North American Plate. The 1964 earthquake was magnitude 9.2.
Understanding Earthquakes
- Magnitude 2.5-4.9: Minor earthquakes, usually felt but rarely cause damage
- Magnitude 5.0-5.9: Moderate earthquakes, can cause damage to poorly constructed buildings
- Magnitude 6.0-6.9: Strong earthquakes, can cause significant damage in populated areas
- Magnitude 7.0+: Major earthquakes, can cause severe damage over large areas
Stay Prepared
If you live in Alaska, it's important to be prepared for earthquakes. Have an emergency kit ready, know safe spots in your home, and follow official guidance during seismic events.
Frequently Asked Questions
How often do earthquakes occur in Alaska?
Alaska experiences varying levels of seismic activity. Our real-time map shows all recorded earthquakes magnitude 2.5 and above.
How is earthquake magnitude measured?
Earthquakes are measured using the Moment Magnitude Scale (Mw), which replaced the Richter scale. Each whole number increase represents about 32 times more energy released.
What causes earthquakes in Alaska?
Earthquakes in Alaska are primarily caused by tectonic plate movement. The region's geological setting makes it prone to seismic activity.
