The UC Berkeley Seismological Lab's DART (Data Available in Real Time) is an essential resource for accessing real-time seismic data. Managed by the Northern California Earthquake Data Center (NCEDC), DART provides structured filesystem access to current and recent timeseries data from multiple seismic networks, including the Berkeley Seismic Networks and various USGS contributions. Users can conveniently access a wealth of data via web browsers or command-line tools, with the DART currently housing the most recent 40 days of seismic data in MiniSEED format.

In addition to real-time data streams, the system offers comprehensive metadata concerning instrument response, and automated data archiving ensures reliable access and integrity of the information provided. The lab utilizes advanced data delivery tools like the IRIS ringserver to ensure efficient handling of seismic events, while also maintaining a rigorous quality control program for archived data. Whether for research, education, or public awareness, DART stands as a vital tool for monitoring seismic activity and understanding the dynamic Earth processes in Northern California.
