- Adm. Harriman Nelson: [Admiral Nelson, Captain Crane and Professor Hollis are discussing what they should do about the radioactive volcano on the island] There's a first time for everything. We've got to try to blow out a volcano before it blows itself out.
- Dr. Hollis: Blow it out?
- Adm. Harriman Nelson: You know, the way you try to blow out an oil fire, only on a much bigger scale.
- Dr. Hollis: It can't be done. A volcano is not an oil well fire, Admiral.
- Adm. Harriman Nelson: I know that, but we're hoping the the radioactivity inside the volcano will blow itself out, if we trigger it with our devices.
- Dr. Hollis: What difference does it make if the volcano blows itself or you blow it out?
- Adm. Harriman Nelson: We're not going to blow it out, we're gonna blow it in.
- [He picks up the communication handset]
- Adm. Harriman Nelson: Missile room, prepare torpedoes tubes 1, 2, 3, and 4 for firing. Implosion warheads, set fuses for 0600.
- Dr. Hollis: What is an implosive warhead?
- Adm. Harriman Nelson: Well, it creates a vacuum by exploding inward, it creates an implosive chain reaction.
- Dr. Hollis: Has such a device ever been used on a volcano?
- Adm. Harriman Nelson: No, but there's nothing we can lose by trying.
