...seismic data...

I didn't know they had recording seismographs in Siberia in 1908. Remarkable.

They didn't. Seismic data from Europe and the US. This puppy was BIG. Recording barometers in England measured the shock wave, the shock wave after it circled the globe, and the shock wave after it circled the globe a second time!
