Frequently asked questions
- How often does Alaska have earthquakes?
- Alaska recorded 1,912 earthquakes of magnitude 2.5 or greater in the past 90 days. Over the last 5 years it has averaged about 49.0 notable quakes (magnitude 5.0 or greater) per year.
- What was the largest recent earthquake in Alaska?
- The largest earthquake in Alaska in the last 5 years was a magnitude 7.0 near 2025 Hubbard Glacier Earthquake.
- When was the last major earthquake in Alaska?
- The most recent earthquake of magnitude 5.0 or greater in Alaska was a magnitude 5.3 near 151 km WSW of Adak, Alaska.
- What magnitude earthquake can you feel?
- Most people begin to feel earthquakes around magnitude 3.0, though it depends on depth and distance. Shallow quakes close by feel stronger than deep or distant ones of the same size.
About earthquakes in Alaska
Most earthquakes are too small to feel. The USGS reports millions of quakes a year worldwide, and the vast majority are below magnitude 2.5. A page showing no recent activity usually means no notable quakes, not that nothing is being measured.
Magnitude is a measure of the energy released at the source; shaking you actually feel also depends on depth and how far you are from the epicenter. A shallow magnitude 4 nearby can feel stronger than a deep magnitude 5 far away.
