Earthquakes in Iceland today: the last 48 hours, explained for travelers

Almost always, and almost never one you would notice: Iceland records between 20 and 200 small quakes on an ordinary day. The verdict at the top of this page says whether the last 48 hours were quiet, normal, active or notable, names the largest quake and where it was, and the table lists every located event from the Met Office.

Yes. Quakes under magnitude 3 are not felt, magnitude 3 to 4 is a short jolt near the epicentre, and even the magnitude 5 caldera quakes under Vatnajökull happen in uninhabited highlands. Buildings are built for it, and the Met Office and civil protection monitor every volcano around the clock. No flight has been cancelled for an Icelandic quake or eruption since 2010.

Sometimes, and the authorities will say so. On the Reykjanes Peninsula, where eruptions have happened most years since 2021, intense swarms with ground deformation have come hours to days before lava; the civil protection service raises an alert, closes Grindavík and the Blue Lagoon, and this page shows the swarm. Swarms at Herðubreið, Bárðarbunga, the Tjörnes zone or Hengill are routine and have led to nothing for years.

Usually a detour and a crowd: the Reykjanes eruptions closed the Blue Lagoon and the Grindavík road for days at a time and left the airport, Reykjavík and the rest of the country untouched. A big ice-capped volcano (Katla, Grímsvötn) would close the South Coast road for a glacial flood; that has not happened since 2011. Check the road conditions page and the civil protection notices rather than the news.

From the Icelandic Met Office’s public listing of located earthquakes in the last 48 hours, read every ten minutes, with each quake assigned to its volcanic system from the coordinates. If the listing cannot be read, the page falls back to the EMSC catalogue, which carries Icelandic events of magnitude 2 and up. The Met Office remains the authority; this page only reads and explains.
