Geology


Madeira is on the African plate and was created by a hot spot. The island itself is only the top quarter of a volcanic system. The cliffs drop below the water surface up to 4,000 m to the seabed.

Since Madeira was formed in several volcanic phases, the first began about 18 million years ago, the last ended only about 6,450 years ago, the exact location of each crater is no longer discernible. Remains can be seen in many places in the interior of the island. Impressive are the former sluices of the volcanoes, which unlike the surrounding rock have not yet been eroded by the erosion. In some places in the high mountains you can also see striking mountain tops or rocky cliffs.

The lava cave Grutas de São Vicente was created during this last phase of volcanic activity. A tubular cavity remained as the effluent lava cooled and solidified on the surface. Below the surface, the lava flowed through this tube at a high temperature and high flow rate.

The rivers of the island usually have a very steep gradient. Numerous waterfalls lead directly to the sea.

The Pico Ruivo is with 1862 m the highest peak of Madeira and at the same time one of the highest peaks of Portugal. The coast of Madeira is steep and rocky. Cabo Girão, the "Cape of Inversion", is the highest cliff in Europe with a height of 580m. Fajã was the name of the hard-to-reach fertile headlands, which served as arable land as well as the small fertile high plateaus, the Achadas.

Funchal

 

The capital Funchal is located on the southern coast of Madeira. The approximately 120,000 inhabitants are spread out into the mountains.

50% of all inhabitants of Madeira live in Funchal!

The runway of the airport was until 2000 so short that jets could start only half refueled and had to land in Porto Santo after 10 minutes flying time. The extension from 1.6 km to 3 km rests on concrete stilts and is referred to in Madeira as Millennium building.

Under the runway there is a sports park. The aircraft noise is barely audible there.
