Pinatubo Volcano is located on the island of Luzon in the Philippines. It is part of the Zambales Mountain Range and is known for its significant eruption in June 1991, which was one of the largest volcanic eruptions of the 20th century. The eruption released massive amounts of ash and gases into the atmosphere, affecting global climate and air travel. The eruption of Pinatubo led to the formation of a large caldera, which is a depression left after a volcano erupts. The surrounding area was heavily impacted, with many communities displaced. Today, Pinatubo is monitored for volcanic activity and is a popular destination for hikers and tourists.
