[edit] Features
Furnas is a stratovolcano and is made up of two caldeiras which date back to approximately 30,000 years ago. The second approximately dates back to 20,000 years ago. The volcanoes are very active with 10 sub-Plinian eruptions occurring in the past 5,000 years. Two of them are historically known. The first known eruption was in 1440 in which the first colonists settled the island. The second was in 1630 and caused 200 deaths. The volcano was intensely studied between 1990 and 2000 and many formally unknown geological risks come to light.
Furnas is also famous for its springs and geysers. The area is known for its spectacular volcanic eruptions.
In Lagoa da Furnas, the fumerolles and mud sands are located at the northern part of the lake. The local delicacy of Furnas is Cozido, a chicken beef stew.
In the village, the area around Furnas has thirty springs, each of which has a different temperature and chemical composition.
There is a hot river which is colored by iron and a cold river which flows through the village.
The geysers are situated in several basins which produce water that is rich in sodium bicarbonate, boron, fluorine and traces of carbon dioxide. The local inhabitants cook corn-type dishes in the geysers.
The installations of hydrotherapy are in the park and were built in the 19th century.
