Mount Arayat is a potentially active stratovolcano located in the province of Pampanga on the island of Luzon, Philippines, rising to a height of 1,033 metres (3,389 ft). The volcano has a breached crater on its northwest side with a smaller andesitic dome in the collapse amphitheater. There are no 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. 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. The Mount Arayat National Park was established in 1933.

Mount Arayat is located in a flat agricultural region at 15°12′N 120°45′E. The southern half of the mountain lies within the municipality of Arayat, Pampanga, while the north half and the mountain summit lies within Magalang, Pampanga. 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.

The mountain is mystical, the legendary home of Aung/Aring Sinukuan/Sinkuan/Suku or the Fairy known as diwata Maria Sinukuan depending on which version of the story the readers or listeners prefer, but in ancient Kapampangan folklore as well as the research gathered by Kapampangan students of Henry Otley Beyer, it was and is the abode of Apung/Aring Sinukuan, rival of Namalyari of Mount Pinatubo, who is in varying versions, the son of Cargon-Cargon who was mortally wounded in a fight with a giant from the Zambales Mountain Range which is said to be the home of Apu Namalyari. The mountain is currently under an immense deforestation threat. Locals have cited that there is a man in the mountain, angry due to the deforestation that was happening. Others say that it was Aring Sinukuan. Wikipedia
