Volcanic activity falls under natural upheaval and geological crises that characterize the end times. The Hebrew term רַעַשׁ (ra'ash) encompasses earthquakes and geological disturbances, which would include major volcanic events as signs of the times.

Major volcanic eruptions can cause atmospheric disturbances affecting celestial visibility, creating darkened skies and altered appearance of sun and moon. While not the prophesied cosmic signs themselves, significant volcanic activity can produce similar visual effects as harbingers.

Volcanic eruptions produce phenomena resembling 'fire from heaven' and can generate hail-like volcanic debris mixed with ash and superheated materials. The supernatural judgment described uses similar natural mechanisms, though this represents only the physical parallel.
