Earthquake Monitor Live Cam

A live earthquake monitoring station in Lincoln, Nebraska, USA—positioned at the geographic center of the United States—utilizes both a Guralp CMG-3T seismometer and an analog pen seismograph sourced from surplus USGS equipment. Originally designed as a carbon soot seismograph, this system has been adapted to detect seismic events with remarkable sensitivity. Identified as seismic station KLNK2, it is capable of registering local earthquakes with magnitudes as low as 3.0 (M3.0) within a 400-kilometer radius of Lincoln. In broader terms, it can detect earthquakes above M3.0 in the central U.S., greater than M5.0 at the national border regions, and above M6.0 worldwide.

Not every minor earthquake produces readable signals due to various factors, including environmental background noise—a challenge amplified by the station's location. While some vibrations detected might originate from non-seismic sources, major seismic events are usually evident on the system's output. Depending on the earthquake's distance from Lincoln, wave propagation times can result in delays ranging from seconds to over 20 minutes before the seismic activity appears on the station's feed.
