In January 2002, a lone man predicted a natural disaster that would impact the lives of hundreds of thousands of people.
Local expert Dieudonne Wafulah had been studying Mount Nyiragongo, a volcano in Congo, for 15 years without pay. He tracked the activity of Nyiragongo and another nearby, smaller volcano for signs of change. Although his equipment had been stolen and vandalized over the years, he persisted in his work.
Then, he saw it. Based on the patterns Wafulah witnessed, Mount Nyiragongo was about to blow. There had been a series of tremors in the earth some months before. Black smoke rose from the mountain. The lava pool inside the crater had shifted and was getting higher.
