Lava flow observed from Mayon Volcano crater, says PHIVOLCS

Mayon Volcano's lava flow represents observable cosmic/geological disturbance. Prophecy 12 describes 'a great earthquake' and 'every mountain and island moved' as signs preceding the great day of the Lord's wrath. While this is a localized volcanic event rather than global cosmic upheaval, it reflects the category of natural/geological signs characteristic of end-times judgment.
