Kanlaon Volcano, the most active volcano in the central Philippines, has erupted 25 times since 1866. Eruptions are typically phreatic explosions of small-to-moderate size that produce minor ash falls near the volcano. On August 10, 1996, Kanlaon erupted without warning, killing British student Julian Green and Filipinos Noel Tragico and Neil Perez, who were among 24 mountain climbers who were trapped near the summit.
