This fault is clearly visible where the river "Ælva" runs into a fault zone, and the city of Porsgrunn grew up along the river's banks. If one looks further to the south, one sees that it sparkles from the many smaller water bodies that lie in the depression that the fault formed in the landscape. We can follow this depression all the way to Kristiansand.

As in Skien, many of the deposits in Porsgrunn are limestone's that were formed at the bottom of a tropical sea about 450 million years ago.
