Cinco Ribeiras is a civil parish in the municipality of Angra do Heroísmo on the island of Terceira in the Portuguese archipelago of the Azores. The population in 2011 was 704, in an area of 12.80 km². Geography Physical geography The parish of Cinco Ribeiras is situated on the southwest coast of the island of Terceira, occupying a roughly triangler swath from the coast to the summit of the volcano of Santa Bárbara in the island's interior. It is an area of approximately , that reaches an altitude of above sea level. It is bordered on the east by the civil parish of São Bartolomeu de Regatos and west by the parish of Santa Bárbara das Nove Ribeiras, as well as, along a short frontier to the north, with the parish of Altares. The parish's southern coast is formed from a high arriba, marked by its only major geological structure, the Ponta das Cinco, a rocky spur formed by a basaltic dike that penetrated one of the radial faults, along the Serra de Santa Bárbara. Yet, running through the region are several smaller volcanic cones composed of black or red basaltic rock. The lower part of the parish developed along a planar zone that corresponds with the terminal area of basaltic fissural flows from the region of Pico da Bagacina, resulting in a gently sloping area towards the northwest. This area is occupied by relatively recent lava flows, with little evidence of pyroclastic eruptive material, translating into shallow soils and rocky covering. Towards the west and interior, the slope gradually increases, passing into a transition zone towards the cone of the Serra de Santa Bárbara. The highest part of the parish, the apex of the administrative frontier corresponds to the watercourses that divide the ravines of Praia da Vitória and Cinco Ribeiras, an area of accentuated slopes, reaching the summit of the caldera of Santa Bárbara (the highest point on the island of Terceira). Apart from this volcano, the parish is little accented, with only the Pico da Praia, at above sea level, representing the highest altitude in the parish. Cinco Ribeiras is crossed by three primary ravines: the Ribeira do Mouro, the Ribeira das Cinco and the Ribeira da Praia, that are part of the radial drainage system, of the Santa Bárbara Massif. Climate Situated along the southwest of the Serra de Santa Bárbara, the parish occupies a transition
