Caldeira das Furnas, Furnas, Povoação, Ilha de São Miguel, Região Autónoma dos Açores, Portugal
Two calderas, with diameters of 7 x 5,5 km and 4,5 x 3,5 km. Within the younger caldera (35000 years old) are numerous pumice cones and maars resulting from Plinian and Phreto-plinian eruptions from 5000 years.
The western of the two calderas is partially filled by a crater lake, Lagoa das Furnas, at an elevation of 359 metres (1,178 ft) and populated by several fumaroles and mud pools are located at the northern part of the lake. In the central part of the village, springs and geysers are prevalent.
From: Wikipedia
The Furnas Caldeiras are one of the Azores' most remarkable geothermal areas, located in the village of Furnas on São Miguel Island. Characterized by boiling springs, bubbling mud pools and steam vents (fumaroles), they create a unique volcanic landscape and are among the region's most visited natural attractions.
As in any area where magma lies relatively close to the Earth's surface, the Furnas Fumarolic Field in Vila das Furnas and the Fumarolic Field at Lagoa das Furnas display impressive geothermal activity. These manifestations include steam emissions, hot springs and other volcanic phenomena that highlight the island's volcanic origin and the powerful geological forces still active beneath the surface.
Curiosity: Several photographs refer to Cozido das Furnas, a traditional Azorean dish and one of São Miguel's most celebrated culinary specialties. Prepared with a variety of meats, vegetables and root crops, the ingredients are assembled the day before cooking and seasoned only with coarse salt, without the addition of water. The meal is then placed in underground pits within the Furnas volcanic area, where it is slowly cooked for five to six hours using the Earth's natural geothermal heat. This unique cooking method gives the dish its distinctive flavor and makes it one of the Azores' most iconic gastronomic traditions.
