|“||Samus, blast the eruption port to get the magma flowing!||„|
The magma-eruption port (also simply known as the eruption port) is a hatch located in the Geothermal Power Plant, which controls the flow of lava in Sector 3 / Pyrosphere on the BOTTLE SHIP. It is situated on the wall of the Power Plant, and removing it will cause a flow of lava to enter the room and the other sectors of the facility.
Anthony Higgs meets up with Samus whilst tracking a purple beast in the Pyrosphere after he is attacked by a Rhedogian and Samus comes to help him. Anthony tells Samus that he was contacted by Adam to meet with the other soldiers in a nearby Navigation Booth and open the magma-eruption port. He comments that it has something to do with restoring the ship's main power, and also that it was somewhat excessive for Adam to send the whole unit to do so. When no one else arrived at the Navigation Booth, Anthony had a look around and was attacked by the Rhedogian.
Later Samus and Anthony meet in the Geothermal Power Plant, following their respective missions where they encounter the monster Samus is tracking, which is attacking them from the shadows. Samus is ordered by Adam to activate her Super Missiles to destroy the eruption port, which sends a huge flow of magma into the room and increases the light, revealing the monster attacking them to be Ridley in clone form.
- The magma-eruption port is thought to be linked to the power production of the area, as Anthony mentions that he has to "restore the power in this place" whilst talking about his mission to open the port.
- The breached magma-eruption port is present in the Pyrosphere stage in Super Smash Bros. for Wii U.
