Nova Iguaçu
Brazilian media began publicizing the hypothesis of a volcano at Nova Iguaçu based on interviews with a geologist who stated it was the only area in Brazil with clear morphology of a volcanic crater and a volcanic cone. In 2004, the Nova Iguaçu Topshopping held the Volcano Exposition, and the Rio de Janeiro State Financial Tribunary declared the volcanic crater to be a natural sightseeing attraction point of Nova Iguaçu and Mesquita. The Nova Iguaçu Municipal Government and the Mesquita Municipal Government helped to distribute the information. These non-academic sources had a special interest in the volcanic crater, commenting that an extremely long eruption lasting from 72 million years ago until 40 million years ago was incompatible with the scientific study of Earth’s volcanoes.
