Godzilla S02E11 - Pacific Peril

When a new island is formed in the Pacific Ocean, the team investigates. Aftershocks from the islands formation end up trapping them in the volcano on the island, which they find is inhabited by giant lizards that eat lava. Worst of all, Godzilla is unable to reach them because he is also trapped by the seismic activity. The others must find a way to escape without Godzilla's help.
