What is Mount Arayat?

Mount Arayat is an inactive basaltic stratovolcano located in the province of Pampanga on the island of Luzon, Philippines, rising to a height of 1,026 metres (3,366 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.[1] The Mount Arayat National Park was established in 1933.[2][3]
