Watch: Lava fountaining on day 99 of Mayon Volcano’s effusive eruption

Volcanic eruptions fall under the category of natural upheavals that Jesus described as 'earthquakes in various places' (σεισμοί κατὰ τόπους) in the end times birth pangs. While the Greek term σεισμός primarily refers to earthquakes, it encompasses geological disturbances including volcanic activity. The prolonged 99-day eruption could be seen as part of the increasing frequency and intensity of natural disasters preceding Christ's return.

The 'fire and blood' (πῦρ καὶ αἷμα) from heaven in the first trumpet judgment has some thematic connection to volcanic lava fountaining, which involves molten rock and fiery material ejected from the earth. However, this is a weak correlation as the Revelation passage specifically describes fire mixed with blood falling from heaven as divine judgment, while this is a natural geological process.
