An excerpt from the article 21 facts about Mount Pinatubo
Mount Pinatubo’s history is divided into two stages—the ancestral Pinatubo and the modern Pinatubo.

The ancestral Pinatubo began about 1,1 million years ago and presented much less destructive activity than the Modern Pinatubo. However, the last eruption, considered at least five times larger than the eruption of 1991, gave birth to what is called the modern Pinatubo, some 35,000 years B.C.
