Chã das Caldeiras Chã das Caldeiras is a volcanic caldera and inhabited volcanic plain on Fogo (island), Cape Verde, known for its active stratovolcano, distinctive agriculture, and resilient community. The site lies within a protected Parque Natural do Fogo context and attracts geologists, volcanologists, and tourists from Portugal, France, Germany, and other nations due to frequent eruptions and unique viticulture. The settlement and landscape are linked to regional transport, scientific institutions, and international disaster response networks.

Geography and geology

The caldera sits near the summit of Pico do Fogo on Fogo (island), forming a highland plateau ringed by volcanic escarpments influenced by the tectonics of the African Plate, Macaronesia, and the Cameroon Volcanic Line. Volcanological studies reference stratigraphy comparable to eruptions documented at Mount Etna, Mount Teide, and historical sequences analyzed by teams from Smithsonian Institution, Instituto Nacional de Desenvolvimento das Pescas e Agricultura (INDP), and universities such as University of Lisbon, University of Cambridge, and Universidade de Cabo Verde. The caldera floor hosts fissure vents, cinder cones, and lava fields with basaltic-andesitic compositions studied alongside analogues at Iceland and Hawaiʻi by researchers affiliated with US Geological Survey, Observatório Vulcanológico de Cabo Verde (OVCV), and the International Association of Volcanology and Chemistry of the Earth's Interior.

History and settlement

Settlement in the caldera traces to colonial-era movements connected to Portuguese Empire migration, land grants associated with Captaincy models, and resettlement following eruptions recorded in colonial archives held at institutions like the Arquivo Histórico Nacional and researchers from Universidade de Coimbra. The community developed wineries, terraced farms, and stone masonry practices transmitted via links to Santo Antão, Brava (island), and maritime routes involving Mindelo and Praia. Displacement episodes prompted interventions from Ministry of Agriculture (Cape Verde), UNICEF, and United Nations Development Programme during 20th and 21st century emergency responses that draw comparisons with relief efforts after eruptions at Mount St. Helens and Eyjafjallajökull.

Volcanic activity and hazards

Pico do Fogo has erupted repeatedly, including major events in 1951, 1995, and 2014–2015 documented by OVCV, Smithsonian Institution Global Volcanism Program, and volcanic hazard teams from European Geosciences Union, Global Volcano Model, and World Bank disaster risk units. Eruptive styles combine effusive lava flows and Strombolian explosions, prompting monitoring by seismic networks using equipment from USGS, Instituto Português do Mar e da Atmosfera, and research collaborations with ETH Zurich and Massachusetts Institute of Technology. Hazards include lava inundation of settlements, pyroclastic emissions affecting América do Sul air routes, gas release monitored by European Space Agency satellites, and lahar risks assessed in coordination with Red Cross and national civil protection agencies modeled after protocols from Japan and Italy.

Economy and livelihoods

Local livelihoods center on viticulture, horticulture, and agropastoralism with wines and fortified products marketed through cooperatives linked to Associação de Produtores de Fogo, export channels in Lisbon, and tourism circuits featuring guided ascents comparable to routes on Mount Kilimanjaro and Mount Fuji. Small-scale commerce interacts with remittances from diaspora communities in Portugal, France, United States, and Belgium, tying household economies to banking services offered via branches of Banco de Cabo Verde partners and microfinance projects supported by UNDP and European Union development funds. Artisanal construction, hospitality services, and scientific tourism provide seasonal income that parallels rural economies on Madeira and Azores islands.

Culture and population

The population comprises Creole-speaking residents with cultural practices influenced by Cape Verdean Creole, Catholic observances tied to Roman Catholic Diocese of Santiago de Cabo Verde, and musical traditions echoing morna, coladeira, and festival patterns shared with communities in São Vicente (island) and Brava (island). Local crafts, oral histories, and culinary traditions incorporate techniques from settlers associated with Fogo (island) families and diasporic returnees who maintain connections to institutions like Casa dos Fidalgos and cultural programs funded by Calouste Gulbenkian Foundation. Population dynamics have been altered by evacuation orders issued by Civil Protection (Cape Verde), migration to Praia and Mindelo, and resettlement initiatives supported by IOM.

Infrastructure and services

Access is via mountain tracks linked to road networks toward São Filipe, Achada Furna, and air connections through São Filipe Airport and inter-island ferries serving ports such as São Filipe (port). Utilities rely on decentralized systems including spring water collection, photovoltaic projects funded by European Investment Bank, and telecommunications provided by operators like Cabo Verde Telecom collaborating with international satellite providers including Inmarsat and Eutelsat. Emergency services coordinate with Civil Protection (Cape Verde), Red Cross, and international volcanology teams from OVCV and academic partners during crises, while heritage and conservation work engages Parque Natural do Fogo management and NGOs such as WWF and ICRC for long-term sustainability.
