Survivor Testimony
Topic: Mount Pinatubo Eruption, Philippines (1991)
“We heard a loud explosion and saw the sky turn dark. Ash fell like rain for hours. The army came later that night and helped us move to safety. We stayed in a school building for weeks.”
— Personal interview with a survivor, collected 1992
The survivor's testimony is considered to be a primary source since it was based on their own experience. The interview was conducted in 1992 on the Mount Pinatubo Eruption in the Philippines that happened in 1991. The purpose of the interview was to share a personal experience of the eruption. It could be targeting the government to help improve disaster response plans or the public to raise awareness and build empathy. This source has value as it offers a direct, emotional insight into what it felt like to experience the eruption, evacuation, and displacement. It also helps readers understand the psychological and social effects, not just the physical destruction. However; it could also be limited as the testimony describes one person’s experience and one location, so it does not represent the situation across all affected areas. It doesn’t include scientific data, government actions, or casualty numbers, so it cannot stand alone for factual analysis.
