Mayon volcano is a beautifully symmetrical volcano with a steep upper slope of 35-40° and is capped by a small summit crater 200 m in diameter. Mayon eruptions produce lava flows, pyroclastic flows and mud flows which threaten populations at the base of the volcano.
Mayon Volcano
Mayon Volcano has had a long history of destructive eruptions. The first recorded eruption occurred in 1616, and since that time about 40 eruptions have claimed more than 1500 lives.
20th December 2009
Mayon volcano was raised to level 4 alert (out of maximum 5) at 2:30 pm on 20th December (local time). During the previous 24 hours, 222 volcanic earthquakes were recorded at Mayon volcano, Philippines. One explosion occurred which produced a plume rising 500 m above the summit. Harmonic tremors were continuously recorded by the seismic instruments. There was an intense crater glow at night and incandescent lava continuously rolled down the slopes. A lava flow extends 4.5 kilometers downslope from the crater along Bonga-Buyuan Gully. Sulphur Dioxide emission increased from 2,034 to 7,024 tonnes per day. At least 40,000 people have been evacuated from the danger zone surrounding Mayon volcano, Philippines. Evacuation centers have been set up in Camalig, Daraga, Malilipot, Sto. Domingo, and Guinobatan towns; and Legazpi, Tabaco and Ligao Cities. Residents are being removed from a 7-km Extended Danger Zone on the southeast flank of the volcano. A lahar risk is present on the southern side of the volcano, and residents have been warned to avoid river channels, especially after periods of rainfall. Lahars following the 2006 eruption of Mayon volcano killed 1200 people. Visit: http://volcanolive.com/mayon.html for further reading...
This is one of the greatest Mayon Action in Albay Philippines. If you want to go there you can park your car maybe few kilometers from the mayon because of its ash falls that can cover your headlight or the full auto lights and mirrors.
