**São Miguel Island**, named for the Archangel Michael (Portuguese: *São Miguel*), is also referred to locally as **"The Green Island"**, is the largest and most populous island in the Portuguese archipelago of the Azores. The island has around 138,000 inhabitants and its largest city, and in the archipelago, is Ponta Delgada.

History
-------

In 1427, São Miguel became the second of the islands discovered by Gonçalo Velho Cabral to be settled by people from continental Portugal.

The first capital of the island was Vila Franca do Campo, which was devastated by a major earthquake and landslides in 1522. The tragedy helped to elevate Ponta Delgada to the administrative and economic status of capital and business centre from 1546.

With the Portuguese Restoration War (1640), the island became a commercial centre, establishing new contacts in Brazil. Some of the island’s historic buildings, including mansions and churches, date from this period; the island's development came from revenues from the export of oranges, mainly to Great Britain.

The period after the Liberal Wars allowed the economy to flourish, and the port of Ponta Delgada expanded, through the export of new crops such as tea, pineapple, and tobacco. The development of the fishing industry, cultivation of staple food and expansion of the dairy industry permitted the growth of many of the towns on the island.

Geography
---------

The São Miguel Island has an area of 744.57 km2 (287.48 sq mi). It is a narrow island; it is 63.54 km (39.48 mi) long (from southeast to northwest) and 15.63 km (9.71 mi) wide (from southwest to northeast).

### Relief

*Lagoa do Fogo* ("Lake of Fire"), as seen from Miradouro da Serra da Barrosa, along the Agua de Pau Massif
The island, of volcanic nature and subject to seismic activity, presents many mountains, mainly in the interior, dominated by the *Pico da Vara*; those mountains are cut by valleys, gullies and streams - the only waterways because there are not rivers.

Lagoa das Sete Cidades
The island consists of an ancient massif in the eastern end, and three stratovolcanoes: **Sete Cidades**, **Fogo** and **Furnas**. The stratovolcano of Sete Cidades is known for its large caldera (Portuguese: *caldeira*) of 5 km (3.1 mi) in diameter and 350 m (1,150 ft) of mean depth; in it there are two small lakes (*Lagoa Verde* to the south and *Lagoa Azul* to north).

In the eastern part of the island is the Pico da Vara (37°48′36″N 25°12′36″W﻿ / ﻿37.81000°N 25.21000°W﻿ / 37.81000; -25.21000﻿ (Pico da Vara)) - the highest mountain of the island - with 1,103 metres (3,619 ft) of altitude. In the central area, is the Sierra de Água de Pau with 940 m height and on the west lies the Caldeira das Sete Cidades, 850 m altitude.

Lying at the eastern end of the island, Pico da Vara is the focus of a Special Protection Area containing the largest remaining laurisilva forest on the island, which is home to the endemic and critically endangered bird, the Azores Bullfinch.

Its fertile lands produce cereals, tea, grapes (for wine), fruits and food for cattle.

### Climate

Similar to other islands in the Azores archipelago, São Miguel is influenced by ocean currents and winds, in particular, the Gulf Stream. It functions as a moderating force in the islands, keeping temperatures hovering between 14 and 26 °C (57 and 79 °F) throughout the year. Rainfall is distributed evenly throughout the year, although it is most abundant in the cool season. The island's location also makes it susceptible to many Atlantic storms.

The Köppen climate classification subtype for the climate of Sâo Miguel Island, in Ponta Delgada, is **Csb** (Mediterranean Climate).

### Human geography

Most towns and cities are in plains, some along the coast and a few in the interior of the island. There are several communities within ancient craters (such as Sete Cidades, Furnas or Povoação), river valleys (such as Ribeira Chã, Pilar da Bretanha) or coastal deltas (Mosteiros).

There are two cities in the islands: Ponta Delgada and Ribeira Grande.

Administrative division
