Mount Pinatubo is located Luzon, an island in the Philippines. Mount Pinatubo is an active volcano and classified as a stratvolcano. It is tall with steep sides formed from layers of volcanic ask. Pumice and hardened lava is formed. The Mount Pinatubo eruption of June 15, 2014 was one of the largest eruptions of the 20th century. The ash cloud of 1991 eruption covered an area of more than hundred thousand square kilometers. The island of Luzon of the Philippines was put into darkness due to the eruption of Mount Pinatubo in 1991. This eruption was about ten times more powerful than the eruption of Mt. St. Helens in 1980. Thousands of people were evacuated but eight hundred people were killed during the eruption. During the eruption of 1991, Typhoon Yunya was affecting the Philippines at the same time and this made things worse for the people of the Philippines. Before the eruption, the US Air Force had two bases on the island of Luzon – Clark Air Base and Subic Naval Base. Following the eruption, Clark has been abandoned and Subic is now controlled by Philippine forces. Volcanologists have predicted that further eruptions will take place in the near future. The eruption formed a crater lake called Lake Pinatubo. It is thought that an eruption of Mount Pinatubo about 35000 years ago was much larger than the 1991 eruption. The Aeta people, who lived on the slopes of the volcano, were the hardest hit by the eruption. Forced to evacuate their homes, they returned to find their villages decimated by the eruption and many of them have been relocated by the government of the Philippines.
