The Sierra Nevada is susceptible to a range of natural hazards, including earthquakes, flooding, and wildfires.

Earthquakes: The Sierra Nevada is located in an active seismic zone, and earthquakes can pose a significant risk.
Flooding: Heavy rainfall, snowmelt, and dam failures can lead to severe flooding in certain areas.
Wildfires: The Sierra Nevada is prone to wildfires, especially during dry periods, which can be devastating to the environment and human communities.

These natural hazards pose challenges to the environment and human activities within the Sierra Nevada and require careful management and mitigation strategies.
