Make Your Own Seismogram!
The UC Berkeley Seismological Laboratory operates a network of seismometers in northern and central California. The Berkeley Digital Seismic Network is an array of high-dynamic range, broadband seismometers. Data from these instruments are transmitted continuously to UC Berkeley for processing and analysis. In addition, data from other seismic networks, such as the NC and NP networks, are archived at the NCEDC. Using this form, you may create a seismogram for the station and channel of your choice.
You may choose from the list of available stations in the Berkeley seismological net below. (See this map of northern and central California for station locations.) Occasional telemetry problems may mean that the station data is unvailable for viewing. Or a station may no longer be active. If you encounter a problem, such as the "Cannot create seismogram -- apparently there is no data" error message, try requesting the data from an earlier or later time period.
