In 1991, Mount Pinatubo erupted and when the ashes started falling from the sky, I thought it was finally snowing in the Philippines. (Forgive me, I was six.) The eruption’s effect was surely felt worldwide. To date, the Pinatubo remains an active volcano. However, it’s been quiet since 1991. One of the results of this eruption was the formation of a crater; which is where I am taking you today. Say hello to the deepest lake in the Philippines (800m deep) and to the people who live close to it.
