Lava flow and pyroclastic currents observed on Mayon volcano, says PHIVOLCS

Mayon volcano's lava flows and pyroclastic currents exemplify the 'earthquakes in various places' and natural upheaval described in Luke 21:11. While this specific eruption is a localized geological event rather than an eschatological sign, it demonstrates the type of environmental crisis that characterizes the end-times birth pangs Jesus described.
