Geology in Sopela

Sopela offers you unique landscapes. It is located in a syncline or U-shaped fold of the earth’s layers. From the neighboring town of Getxo you can see the strata to the northeast, while in the vicinity of Sopela they lean to the northwest.

The rocks tell us that it happened millions of years ago and for this the geologists rely on the fossils found in the different layers of strata. In addition, its shape and its inclination are for geologists like pages of a book waiting to be read. Thanks to those pages, today we know that Uribe Kosta, the region in which our municipality is located, was submerged under the sea. Fossils of ammonites and inoceramids have been found in the surroundings of Atxabiribil, one of our beaches, which bear witness to this.

In Sopela, visitors have the chance to see one of the main examples, on the Cantabrian coast of Flysch; a kind of puff pastry in which the alternation of the layers can be perfectly observed. There are soft rock strata; like loams and clays and others of harder rocks; such as sandstone and limestone, this causes erosion to wear away the softer layers first, revealing that curious “cake” shape. This geological series presents layers of different ages, younger and younger from E to W, up to a fracture that gives way to a set of materials of the same age as the initial ones.
