Current and Historical Earthquake Activity

The INL Seismic Monitoring Program collects and compiles earthquake data to develop an understanding of earthquake processes and the potential for future, large magnitude earthquakes. The INL acquires earthquake data in real-time; INL seismologists analyze the data to determine information about the earthquakes. The INL reports information about earthquakes that occur within a 161-km (100-mile) radius of INL. This earthquake data and data from other nearby seismic networks are compiled into a regional historical catalog. The historical earthquake catalogs are used in seismic hazards assessments to determine the locations of active zones, maximum magnitudes (or size) of possible future earthquakes, the frequency of earthquakes (or repeat times), and the types of faults.
