AFTER THE BLAST
Before the catastrophic eruption of
1991, Mount Pinatubo was a rugged peak
covered by dense rainforest. The eruption
emptied the magma chamber beneath the
volcano, making most of the peak collapse
into the void below. This formed a giant
crater—a caldera—which soon filled with
water to create Lake Pinatubo.
