Laptev Sea Rift Seismological Network (SIOLA) Part I
The Laptev Sea region is one of the very few places on Earth where mid-ocean spreading centres continue into continental rift zones. The Gakkel Ridge, the active spreading centre in the Eurasia Basin of the Arctic Ocean, is characterized by well-defined seismicity close to its axial graben. In contr...

The Laptev Sea region is one of the very few places on Earth where mid-ocean spreading centres continue into continental rift zones. The Gakkel Ridge, the active spreading centre in the Eurasia Basin of the Arctic Ocean, is characterized by well-defined seismicity close to its axial graben. In contrast below the Laptev Sea Shelf, which consists of a series of sediment filled grabens (500 km wide, 700 km long), only more diffuse seismic activity is observed. The pre-rift basement in the Laptev Sea is most probably formed by Late-Paleozoic and Late-Mesozoic fold belts. The Laptev Rift Basin is filled with Upper Cretaceous and Cenozoic sediments of variable thickness (1.5 to 14 km).
