‘Porta do Inferno’; conheça o mistério das crateras

A cratera de Batagaika, na Sibéria, conhecida popularmente como "Porta do Inferno", se expande em até um milhão de metros cúbicos por ano devido ao derretimento do solo congelado.

A “Porta do Inferno” localizada na Sibéria possui um quilômetro de extensão e foi descoberto em 1991 por meio de imagens de satélite, após o colapso de uma encosta nas terras altas de Yana, na Rússia.

Segundo um estudo publicado no jornal científico "Geomorphology", a cratera da Sibéria cresceu 200 metros desde 2014, chegando a uma largura de 990 metros. A situação preocupa as autoridades.

Já no caso da “Porta do Inferno” localizada no Turcomenistão, trata-se da cratera de Darvaza, uma ex-república soviética, na Ásia Central.

Com 69 metros de largura e 30 metros de profundidade, a cratera de Darvaza emana o gás natural que queima há décadas.

A teoria mais difundida sobre a “Porta do Inferno” do Turcomenistão, diz que em 1971, vários geólogos soviéticos estavam perfurando o deserto com o objetivo de encontrar petróleo, mas encontraram a reserva do gás. Com isso, a terra teria sumido e formado sumidouros.
