Santo Antao, entirely made up of volcanic material. The tallest mountain is Topo de Coroa, reaching a height of 1,979 m. The second tallest is Pico da Cruz at 1,585 m. The island is divided into north and south by a mountain range long considered impenetrable but now crossed by a road. Santo Antao’s main town is Ponta do Sol on the north coast, home to an airport, while its ferry port is Porto Novo on the south coast. A part of the island in the southeast has an arid climate, while the northwest receives relatively normal precipitation. Its valleys are suffering heavy erosion. Santo Antao is considered one of the most mountainous of Cape Verde. Its mountains are composed of basalt. Many of its volcanoes are young, especially its calderas. Since 1999, vulcanologists have observed continuous rising of the water temperature of the sea in the area of Ponta do Sol which may indicate the risk of a new eruption in the area
