What Happens, Part by Part (Contains Spoilers)
The coded message
In Hamburg, Professor Lidenbrock finds a slip of parchment written in runes inside an old Icelandic saga. Axel accidentally discovers that the message reads backwards in Latin. It says that the alchemist Arne Saknussemm reached the center of the Earth by going down the crater of Snæfellsjökull, where the shadow of the peak Scartaris falls at the end of June.
Iceland and the descent
The professor and a reluctant Axel travel to Iceland and hire the quiet guide Hans. On the right day, the shadow points to the correct chimney, and the three men climb down into the extinct volcano. They follow lava tunnels and stone passages deeper and deeper, measuring heat and pressure as they go.
Thirst and getting lost
Their water runs out in a dry passage, and Axel nearly dies before Hans finds an underground stream, which they name the Hansbach. Later Axel takes a wrong turn and becomes lost alone in the dark. By a strange effect of sound in the tunnels, he hears the others' voices, and after a fall he wakes up safe with them.
The underground sea
The explorers reach an enormous cavern lit by an electric glow, with a sea they call the Lidenbrock Sea. They build a raft and cross it, passing forests of giant mushrooms. They see two sea monsters fight, survive a storm, and later find a field of bones and a giant prehistoric herdsman watching a herd of mastodons. They also find Saknussemm's initials carved in the rock.
The eruption and return
A boulder blocks the path, so they blast it with gunpowder. The explosion opens a chasm, and the sea rushes down, carrying the raft into a volcanic shaft. They are pushed upward on a rising column of lava and water, and are finally thrown out of Stromboli in southern Italy. They return to Hamburg as heroes, and Axel marries Gräuben.
