Eruptions occur predominately from the central conduit and have also produced lava flows that travel far down the flanks.
Rising from the sea at the Albay Gulf, it rumbled, pumped out lava and spewed ash periodically in 19 and 2004.Sounds like thunder were heard; house-size rocks were ejected and material was sent 13 kilometers into the atmosphere; lava flowed five kilometers from the crater; and ash buried towns 10 kilometers to the southeast.Military trucks were called in to help evacuate people from an area within eight kilometers southeast of the crater deemed to be “in great danger” from pyroclastic flows, volcanic blasts and ground surges.According to Phivolcs: The "most destructive eruption" of Mayon on record was in 1814 (See Below).The second most destructive eruption of Mayon occurred between June 4 and July 23, 1897, when pyroclastic flows damaged the seashore of Sto. Nino, San Isidro, San Roque, San Antonio, Misericordia in Sto. There were at least 350 casualties, "most likely due to pyroclastic flows," Phivolcs said.One man died in the evacuation but no one died directly from the eruption. Mayon is Cagawa, which is 16 kilometers away from the volcano's base.
When the volcano is not so volatile it is possible to climb to the crater in two or three days.
The north side of the mountain is lush and dotted with plantations.
The south side of the mountain is a dead zone of ashy ravines and gullies.
It is a perfect stratovolcano and it erupts very frequently.
Mayon volcano is 2462 meter-high (8,077 foot-high). An eruption in 1814 killed 1,200 people and buried an entire town.
In February 2000, lava and pyroclastic flows were seen coming down its eastern slopes.
