Spectros Without Borders

These spectrographs show various live earthquake seismographs from around the Pacific Ocean Rim.
Here's how to read the graphs:


The program used to provide this live stream is Swarm, a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamic data sources, including Earthworm waveservers, IRIS DMCs, FDSN, SEED and SAC files, and simple ASCII. Swarm was written by and for scientists. The code is open source, freely available, and in the public domain. Swarm was developed in 2004 and 2005 at the Alaska Volcano Observatory by Dan Cervelli, Peter Cervelli, Thomas Parker, and Thomas Murray.

The purpose of this live stream is for educational and research purposes only.
