Examples of earthquakes detected by the system.

The left video shows an earthquake with a magnitude of 6.5 that happened outside the network with a distance of 360 km west side of the network. 

The right one shows an earthquake with a magnitude of 3.1 that happened within the network. 

Our system has been monitoring a seismometer network in the Yellowstone region. This region has around 30 stations, and each station has several channels where each channel can be viewed as an individual stream. It formed a total of 95 streams in this network. If we only pair the streams from the same channel of different stations, we have around 628 pairs to compute the correlation. 

In the visualization site, we use the color and transparency of a line to represent the lagged correlation between the two stations. The correlation between two stations is defined as the maximum correlation value among all the channel pairs under the two stations. The correlation value from 0 to 0.5 is mapped to the transition of color from green to yellow, while the correlation from 0.5 to 0.9 is mapped to the transition from yellow to red. The black edge represents the correlation value greater than 0.9. The alpha of the edge is the same as the correlation value.
