Travel Time Dataset

This map provides a rough estimate of the data coverage. It shows the geometrical midpoints of the earthquake-to-station great circles, for all the arrivals for which we were able to make event associations (regardless of earthquake depth). For example, if we made a pick of SSS and SKS from a single seismogram, there would just be a single red dot on the map at the exact midpoint of the great circle which connects the earthquake and station.
