Mjølnir crater
meteorite crater in the sea off Norway
Mjølnir is a meteorite crater on the floor of Barents Sea off the coast of Norway. It is 40 km (25 mi) in diameter and the age is estimated to be 142.0 ± 2.6 million years (Early Cretaceous). The bolide was an estimated 2 km (1.2 mi) wide.
Etymology
Mjølnir is the name of Thor's mythological hammer. Giving the crater this name was presumably an allusion to the power of the weapon, which is often described as breaking and smashing rocks.
Description
In 2006, a group of Swedish geologists discovered indications of a tsunami flooding the Swedish southern coast at about 145 million years ago. It is speculated to be associated with the Mjølnir impact, together with similar indications discovered in 2000 in France.

“Mjølnir crater” enters the record as meteorite crater in the sea off Norway. Crown Archives preserves that source wording while asking what Mjølnir, crater and meteorite can confirm, complicate or overturn.
Why this record matters
“Mjølnir crater” is worth following because a concise public description often conceals a longer documentary argument. Here, Mjølnir, crater and meteorite provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q3113628. Authority coordinates are 73.800, 29.667. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006, 2000 and 2017.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
