Mount Arayat

Mount Arayat is an isolated potentially active stratovolcano in the Central Luzon plains, Philippines. Located within vast agricultural lands of Pampanga province, it rises prominently to a height of 1,033 metres (3,389 ft) above sea level. Its southern half lies within the municipality of Arayat, while its north half and summit lies within Magalang. Ten miles (16 km) to the west of Mount Arayat is Angeles City and the former Clark Air Base. The active volcano Mount Pinatubo is located 26 km (16 mi) west, while Manila is located 75 km (47 mi) to the south. Mount Arayat was officially declared a national park in 1933 and a tourist spot in 1997.[2][3][4] The mountain is currently under an immense deforestation threat.[5]

Not to be confused with Mount Arafat, Mount Aragats, Mount Ararat, or Mount Malarayat.

Mount Arayat has a breached crater on its northwest side with a smaller andesitic dome in the collapse amphitheater. There are historical records of eruption in Arayat and the only dated rocks are 530- and 650-thousand-year-old basalts predating the collapse and formation of the lava dome. However, weak steaming is currently present in some of the heavily eroded vents on the North Western side of the summit. Additionally an analysis report indicates that the volcano erupted over the last 2,000 years, but it is believed to refer to the volcanic activity of the volcano.[1]


Mount Arayat is considered mystical in ancient Kapampangan folklore as the legendary home of Aung/Aring Sinukuan/Sinkuan/Suku or the Fairy known as diwata Maria Sinukuan. According to research gathered by Kapampangan students of Henry Otley Beyer, the mountain was the abode of Apung/Aring Sinukuan, rival of Apu Namalyari of Mount Pinatubo.

History[edit]

Philippine Revolution[edit]

During the Philippine Revolution, the Filipino revolutionaries retreated on Mount Arayat after the failure of the Cry of Nueva Ecija during September 1896 when the Spanish counter-attacked at San Isidro.


In September 1897, Gen. Francisco Macabulos retreated to Mount Arayat along with his men to avoid capture by the Spanish authorities in Tarlac, which used to be under the control of his forces. Several engagements would occur here afterwards until his surrender on January 15, 1898.

World War II[edit]

On Mount Arayat, Colonel Thorpe, an American guerrilla officer, was captured by Japanese forces on December 10, 1942.


Mount Arayat would then be used as a hiding place for communist Filipino guerrillas called the Hukbalahap afterwards. Nicanor Songco "Bapa" developed a plan on how they could spread the information of their escape to Mount Arayat to be safe in the height of the war. This plan would be the reason for the survival of their family from Bulacan, Pampanga and Nueva Ecija who joined them at that time. When they found out that the Japanese soldiers had arrived at their place, they quickly left and went to Mount Arayat but when they were about to go up, the officers of the Japanese soldiers came to arrest him. Nicanor surrendered to ensure everyone's safety. He was tortured by having his skin removed from his arm. Following this, he was released by the Japanese soldiers and he was able to return to Mount Arayat and his family.

Eruptions[edit]

There are no cultural records of historical eruptions. However, weak steaming is currently present in some of the heavily eroded vents on the North Western side of the summit. The ancient eruptions were said to have caused the formation of a Lava Dome on the Western Slopes of the mountain known as White Rock which makes a nice tourist destination and is usually a field trip destination for students of Pampanga State Agricultural University. The Arayat amphitheatre is said to have been caused by the summit's collapse on the western side but a much deeper crater is present on the eastern side, it was said that the mountain was once a volcanic island, until eruptions covered the surrounding area with soil, eruptions were said to be the possible cause of a theorized re-route of Pampanga River which is said to have once passed on the western side rather than eastern side where it currently moves.[1]

Conservation efforts[edit]

In April 2022, President Rodrigo Duterte signed a law declaring Mount Arayat as a protected landscape under the National Integrated Protected Areas System.[12]
