Lava fountain from the summit crater of Mayon in the Philippines seen on January 23, 2018. This lava fountain is likely a few hundred meters tall. PHIVOLCS. In the Philippines, Mayon is erupting spectacularly, creating a lava flow that stretches over 3 kilometers (2 miles) from the crater, 600-meter lava fountains, pyroclastic flows that followed gullies for 5 kilometers (~3 miles) from the summit and explosions that are sending ash and volcanic debris over 3-5 kilometers (10,000-15,000 feet) into the air.
