On Smogon's Movedex:

Eruption (Japanese: ふんか Eruption) is a damage-dealing Fire-type move introduced in Generation III.

Effect

Eruption deals damage. It has 150 base power at maximum HP, but its base power decreases proportionally to the user's remaining HP.

Specifically, its base power is equal to ${\bigg \lfloor }{\frac {150\times HP_{current}}{HP_{max}}}{\bigg \rfloor }$ . However, if this formula produces a value less than 1, the move's base power becomes 1 instead.

In a battle with multiple opponents, Eruption targets all adjacent opponents. Eruption will also destroy round rocks found in the background of battles.

Eruption can be used as the second move of a Pokémon Contest combination, with the user gaining 1 bonus appeal point if Earthquake, Endure, or Sunny Day was used in the previous turn.
