Loki Earthquakes

‘Now Loki was captured without quarter and taken to a certain
cave. Then they took three stone slabs and set them on edge and
knocked a hole in each slab. Then Loki’s sons Vali and Nari or
Narfi were fetched. The Æsir turned Vali into the form of a wolf
and he tore his brother Narfi to pieces. Then the Æsir took his
guts and bound Loki with them across the three stones - one
under his shoulders, one under his loins, the third under the backs
of his knees — and these bonds turned to iron. Then Skadi got a
poisonous snake and fixed it up over him so that the poison would
drip from the snake into his face. But his wife Sigyn stands next to
him holding a basin under the drops of poison. And when the
basin is full she goes and pours away the poison, but in the mean-
time the poison drips into his face. Then he jerks away so hard
that the whole earth shakes. That is what you call an earthquake.
There he will lie in bonds until Ragnarok.’


- Prose Edda, Gylfaginning

----------

And after that Loki hid himself in the waterfall of Franangr, in the shape of a salmon. There the Æsir caught him. He was bound with the guts of his son Nari. But his son Narfi turned into a wolf. Skadi took a poisonous snake and fastened it over Loki’s face; poison dripped down from it. Sigyn, Loki’s wife, sat there and held a basin under the poison. But when the basin was full, she carried the poison out; and meanwhile the poison fell on Loki. Then he writhed so violently at this that all the earth shook from it; those are now called earthquakes.
