Broadband Seismometer: A seismometer designed to record seismic waves over a wide range of frequencies with high fidelity.
Seismic Hazard Assessment: The process of estimating the probability and intensity of future earthquakes in a specific region.
Induced Seismicity: Earthquakes that are caused by human activities, such as hydraulic fracturing or reservoir impoundment.
