The “La Cueva de los Verdes” lava tube in Lanzarote, Spain, is one of the world's largest volcanic cave complexes with a total length of about 8 km.

Geology experts from ESA's Pangaea-X campaign mapped most of the lava tube system as part of a project supported by local authorities Cabildo of Lanzarote and the University of Padova, Italy. The data was acquired in November 2017 by Leica Geosystems.

The map comes alive in great detail in 3D, helping institutions to protect the subterranean environment. The map also provides scientific data to study the origins of the tube and its peculiar formations.

Pangaea-X is a test campaign that brings together geology, high-tech survey equipment and space exploration. Learn more about the science and technology behind this campaign visiting http://blogs.esa.int/pangaea
