Mount Arayat is a potentially active stratovolcano sleeping 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 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] The Mount Arayat National Park was established in 1933.[2][3]
