The MBMG provides research and information on Montana’s active faults that demonstrate fault activity during recent geologic time (Quaternary faults) and have the potential to generate damaging earthquakes.

The Earthquake Studies Office monitors, analyzes, and reports on Montana earthquakes and makes these data available to the scientific community and the public.

The Landslide Hazards Program aims to identify, map, and categorize landslide areas across the State of Montana.
