Meager is an unstable volcano. It is built of unstable volcanic and has dumped clay and rock several meters deep into the Perberton Valley at least three times during the last 7,300 years. Two earlier debris flows, around 4,450 and 7,300 years ago, sent rubble at least 32 kilometers from the volcano. Recently, the volcano has created smaller landslides about every ten years, including one in 1975 that killed four geologists near Meager Creek. Logging, mining, tourism and wilderness recreation on nearby slopes and valleys are vulnerable to the volcano’s excellent geomorphic activity. The possibility of Mount Meager covering settled parts of the Pemberton Valley in a debris flow is estimated at one in 2400 years. There is no sign of volcanic eruptions with these events, however scientists warn the volcano could release another massive debris flow over populated areas anytime without warning.
