Basic Information About Volcanoes

For the Verbal Leaners:

Overview

     The Philippines is at the heart of the Pacific Ring of Fire, and is home to over 300 Volcanoes, 53 of which are active, the rest have been dormant in recent history, The Philippines has the 6'th most number of active volcanoes per square feet, that many volcanoes in such a small area, causes a major volcanic eruption, every couple of decades.

Luzon

Taal Volcano

Restless / Active

Taal volcano with its lake-filled 15x20 km wide Talisay (Taal) caldera is a beautiful caldera volcano, but also one of the most active and dangerous volcanoes of the Philippines. Taal has had some of the country's largest and deadliest eruptions: At least 6 eruptions during the recorded history of Taal since 1572 claimed fatalities, mostly from powerful pyroclastic flows, as well as tsunamis produced in the crater lake.

Mt. Pinatubo

Active

Pinatubo was a little known volcano and it had been dormant for 400 years. There were no known historic eruptions. Before the eruption in 1991 Pinatubo was 1745 m high (ca. 250 m more than now), and was only 200 m higher than the nearby peaks, which are remnants of older volcanic edifices of Mt Pinatubo and hid it from views from distance. Pinatubo is mostly noted for a failed geothermal development project.

Mayon

Active

Mayon, also known as Mount Mayon and Mayon Volcano, is an active stratovolcano in the province of Albay in Bicol Region, on the island of Luzon in the Philippines. A popular tourist spot, it is renowned for its "perfect cone" because of its symmetric conical shape, and is regarded as very sacred in Philippine mythology.

Arayat

Potentially Active

Arayat is a forested stratovolcano above the flat Central Plain of Luzon Island and located NE of Angeles city, Philippines. It belongs to the Eastern Volcanic Chain, which includes Mounts Balungao, Cuyapo, Amorong and Arayat volcanoes. Mt. Arayat's cone is probably built upon an older crater of 900 m diameter, whose remnants form the northern (1026 m) and southern (920 m) peaks.There are no known eruptions in historic times, but weak fumarolic activity is present on the NW summit of Arayat volcano.

Visayas

Biliran Volcano

Dormant

Biliran volcano is at the northern end of a 170 km long volcanic chain extending SSE to Panaon Island. The only known historic activity took place on 26 September 1939 and consisted of a phreatic explosion accompanied possibly by a debris avalanche. Ash fell in Caibiran town 12 km to the E.

Banton Island Volcano

Dormant

Banton has a total land area of 3,248 hectares (32.48 km2). Based on rock petrology, the island is a dormant volcano that lies at the southernmost portion of the Pleistocene-Quaternary West Luzon volcanic arc and may have been active during the Pliocene period.

Kanloan Volcano

Active

Kanlaon, also known as Mount Kanlaon and Kanlaon Volcano, is an active stratovolcano and the highest mountain on the island of Negros in the Philippines, as well as the highest point in the Visayas, with an elevation of 2,465 m above sea level. Mount Kanlaon ranks as the 42nd-highest peak on an island in the world.
Mt. Kanlaon bisects the Negros Island, and it is also the highest peak in Central Visayas. This makes it popular among mountain climbers and hikers. The fact that it is an active volcano adds a certain kind of thrill.


Mandalagan Volcano

Potentially Active

Mount Mandalagan is a complex volcano located at latitude 10.65° North, longitude 123.25° East, in the province of Negros Occidental, on the north of the island of Negros of the Philippines. It is located inside the Northern Negros Natural Park. Mandalagan is a solfataric, fumarolic, potentially active stratovolcano.
Mandalagan is a solfataric, fumarolic, potentially active stratovolcano. Mandalagan is also known as Nahigda nga Babayi or Lying Women for the Bacolodnons and Negrenses.

Mindanao

Mt. Apo

Dormant

Apo volcano is the highest mountain in the Philippines, and its name means "Master" or "Grandfather". There are no known historic eruptions .Apo volcano is an a basaltic to basaltic-andesitic stratovolcano and part of the Central Mindanao Arc, but its volcanic history is poorly known. The densely forested volcano has a flat summit with 3 peaks, the highest of which in the SW is known as Davao volcano and has a 500 m wide crater with a small lake.The youngest crater is located on the northern peak. Several fumaroles and sulfur deposits occur on the volcano, most notably fumaroles along a fissure on the SE side down to 2400 m elevation.The Mt. Apo Geothermal Field is a 8.4 km2 geothermal exploration field near Mt Apo, which has been being exploited since October 1996.

Balatukan

Extinct

Balatukan (also known as Balingoan or Balatocan) is a massive compound stratovolcano on the SW shore of Gingoog Bay, 15 km SW of Gingoog city in north-central Mindanao, opposite Camiguin Island, Philippines.Lava flows on its flanks are 140,000 years old and it is not known whether there are younger volcanic products. Although the volcano still has fumarolic activity, it might be extinct, as the strong degree of erosion of its flanks suggests.


Balut Volcano

Probably Extinct

Balut volcano (also known as Sanguil) is a small island of the Sarangani group south of the Batulaki Peninsula at the south end of Mindanao Island in the Philippines.The age of the last activity on Balut volcano is unknown, but hot springs and thermal areas are active on the W and SW flanks of the volcano.


Hibok-Hibol Volcano

Dormant

Hibok-Hibok volcano (also known as Catarman volcano) is the youngest and the only historically active volcano on Camiguin Island, which is located 9 km off the north coast of Mindanao Island, Philippines. Camiguin island itself is a 292 sq. km oblate, 20 km long island composed of 4 overlapping stratovolcanoes and some flank cones. Eruptions of Hibok-Hibok volcano are often Pelean-type, i.e. dome building and the generation of nuées ardentes (hot pyroclastic flows generated by partial dome collapse).Prior to the 1948 eruption, sulfur was mined at the crater of Hibok-Hibok.

How do Volcanoes affect the Philippines?

     When eruptions risk the lives and properties of Filipino communities, those who live on the mountains or hills are put at a disadvantage to flee. The Philippines' physical geography can help the lava and lahar to move quicker. Knowing how and where volcanoes have amassed is important in knowing which areas are the most prone to volcanic activity and eruption.

Socially

Aside from the deaths and injuries caused by the volcanic activity, the destruction of people's homes and communities can have severe negative consequences for the people affected. When it comes to the health effects of an eruption, the World Health Organization (WHO) has listed the following health impacts: trauma and injuries, skin burns and irritation, gastrointestinal problems, lung problems, and eye irritation. Trauma and the inability to recoup from their losses can be detrimental. Environmental destruction, resource, and architectural loss also play into these effects.

Economically

When business industries are disrupted by disasters like volcanic eruptions, people are unable to work and therefore have to sustain themselves with the few resources of money and food they have. Spewing volcanic ash and debris from the destroyed infrastructure can contaminate water supplies and prevent business, factories, and water treatment plans from operating. Lahars and lava flows can destroy entire areas and send their land value into the ground.

Environmentaly

Volcanic eruptions, as we all know, are very destructive and have the ability to cause mass destruction to the natural environment. Lava burns down forests and everything in its path, and lahars can flood certain areas to a ridiculous amount. This volcanic activity also causes severe health problems to all humans and animals.

Dealing With The Threat

   As always, no storm can bring a united Filipino people to its knees. It is my hope that we all stay safe in the coming days.

Evacuation

Whenever there is volcanic activity/eruptions the Filippino government has always tried to evacuate the people in affected areas. The Philippines and its volcanoes are a strong symbol to the world about the dangers of volcanoes and the risk of being situated on the Pacific Ring of Fire. The Philippines is a country that can positively be taken advantage of in discovering and learning about volcanic activity, eruptions, prevention, and recovery; the rest of the world can benefit from its diversity.

Information

Knowing how and where volcanoes have amassed is important in knowing which areas are the most prone to volcanic activity and eruption. This also teaches us why there is such a high concentration of volcanoes in the Philippines and gives organizations such as the Philippines Institute of Volcanology and Seismology (PHIVOLCS) an opportunity to warn government and citizens about potential volcanic activity, eruptions, lahars, etc.

How to Stay Safe During a Volcanic Eruption

According to ready.gov, these are what we can do if we are under a volcano:

Listen for emergency information and alerts.

Follow

Follow evacuation or shelter orders. If advised to evacuate, then do so early.
Avoid areas downstream of the eruption.

Protection from the Ash

Protect yourself from falling ash.
Do not drive in heavy ashfall.

Avoid Inhaling the Ash

Using a Cloth, or a mask, limit your exposion to ash, They are terrible for your body
