ACTIVE VOLCANOES IN THE PHILIPPINES - All of the volcanoes in the Philippines are part of the Pacific Ring of Fire, a major area in the Pacific Ocean where many of the world’s earthquakes and volcanic eruptions occur. According to the United States Geological Survey (USGS), about 90% of the world’s earthquakes and all but three of the world’s 25 largest volcanic eruptions occurred along the Ring of Fire. There are 452 volcanoes in the Ring of Fire including The Andes in South America, Popocatepetl in the Trans-Mexican Volcanic Belt, Mt. Saint Helens in the US Pacific North West, Alaska’s Aleutian Islands, Mt. Fuji in Japan, Krakatoa in the Indonesia Island Arc and Mt. Ruapehu in New Zealand. According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), at least twenty-four (24) of these volcanoes are active or potentially active, while the rest are dormant. Based on documented eruptions over the years, the six most active volcanoes are: Mayon – since 1616, Mayon has erupted 47 times. Taal – since the sixteenth century, Taal has erupted more than 30 times. Kanlaon – erupted 30 times since 1819. Bulusan – erupted 15 times since 1885. Hibok-Hibok – erupted five times in modern history. Pinatubo – erupted in 1991 after being dormant for 600 years. From June 12 to June 16, 1991, the volcano erupted four times. Volcano safety tips are provided on what to do in case a volcano erupts in your area.

Active Volcanoes in the Philippines
Kara Santos



With Taal Volcano’s ongoing eruption, everybody’s on edge.
Thousands of residents who live near the lake have been displaced and animals have been abandoned on the island.

The landscape of Taal’s Volcano Island will probably never be the same again.

It’s scary to think of what could happen in the future. It makes you wonder how prepared we are considering that the Philippines is an archipelago of more than 7,100 islands, most of which are volcanic in origin. In fact, there are at least 300 volcanoes in the country.

Volcano safety tips
What to do during a volcanic eruption
Follow the evacuation order issued by authorities and evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast and lava flow.
Be aware of mudflows. The danger from mudflow increases near stream channels and with prolonged heavy rains.
Mudflows can move faster than you can walk or run. Look upstream before crossing a bridge and do not cross the bridge if a mudflow is approaching.
Avoid river valleys and low-lying areas. Remember to help your neighbors who may require special assistance – infants, elderly people and people with disabilities and pets.
Protection from falling ash
Listen to a battery-powered radio or television for the latest emergency information.
If you have a respiratory ailment, avoid contact with any amount of ash.
Wear long-sleeved shirts and long pants.
Use goggles and wear eyeglasses instead of contact lenses.
Use a dust mask or hold a damp cloth over your face to help with breathing.
Stay away from areas downwind from the volcano to avoid volcanic ash.
Stay indoors until the ash has settled unless there is a danger of the roof collapsing.
Close doors, windows and all ventilation in the house (air conditioners, fans and other vents).
Clear heavy ash from flat or low-pitched roofs and rain gutters.
Avoid running car or truck engines. Driving can stir up volcanic ash that can clog engines, damage moving parts and stall vehicles.
Avoid driving in heavy ash fall unless absolutely required. If you have to drive, keep speed down to 20 km/h or slower.
