About Earthquake Activity in Iceland
Iceland sits on the Mid‑Atlantic Ridge, where the North American and Eurasian plates pull apart. Learn more about seismic activity in Iceland below.
The largest earthquake recorded in Iceland in the past 100 years was M6.9 in 1963 (41 km W of Siglufjörður, Iceland). The region is defined by Reykjanes Rift Zone, Tjörnes Fracture Zone, South Iceland Seismic Zone, and the risk level is classified as Moderate.
With a population of 370,000, understanding local seismic hazards is crucial. This page provides real‑time USGS data and historical context for Iceland.
Why does Iceland experience earthquakes?
Iceland lies on Mid-Atlantic Ridge (divergent boundary). The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In strike‑slip regions like the San Andreas, plates slide past horizontally.

Frequently Asked Questions about Iceland Earthquakes
❓ What was the strongest earthquake in Iceland?
The largest earthquake recorded in Iceland in the past 100 years was M6.9 in 1963 (41 km W of Siglufjörður, Iceland).
❓ Is Iceland on a fault line?
Yes, Iceland is crossed by Reykjanes Rift Zone, Tjörnes Fracture Zone, South Iceland Seismic Zone, making it prone to seismic activity.
❓ How often do earthquakes occur in Iceland?
Due to its tectonic setting (Mid-Atlantic Ridge (divergent boundary)), Iceland experiences hundreds to thousands of earthquakes each year, though most are too small to feel.
❓ What should I do during an earthquake in Iceland?
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks.
