Chief angels showed Enoch two lakes of fire for ultimate judgement by God: one for fallen and excessively aggressive angels and the second for spiritually blind and umrepentant humans. The first is described as currently existing. The second will appear at the judgement. The description of the first sounds like the Mid-Atlantic Ridge discovered below the seas stretching north to south in the Atlantic Ocean where the ocean floor of the whole planet splits apart constantly with endless fire and magma constantly spilling out. There is no known feature on Earth like it - a chasm of fire stretching deep into the abyss of the earth's crust and running from Iceland to Antarctica. This sounds so similar to the description given by Enoch so it serves as an ilustration of what awaits us if we die in our sins.
