Jon Major
My research focuses on hydrological hazards associated with volcanic eruptions and landscape responses to large inputs of sediment, including from dam removals. Projects focus on: (1) identifying hydrogeomorphic processes altered by volcanic disturbance; (2) evaluating hydrogeomorphic consequences; and (3) quantifying characteristic hydrogeomorphic response times and durations.
