This stream is showing the past 48 hours of USGS reported earthquakes + the last 50 EMSC reported earthquakes internationally.
No voice in this video unless a large earthquake strikes.
Marker height off the globe = depth into the Earth.
The feed may show double earthquakes in some locations due to both USGS + EMSC agencies reporting the events.
When an earthquake strikes, you will hear a rumble, ding, and a bell toll. The bell will toll the number of times = to the earthquake which occurs. (example : M4.0 will ring 4 times).
The most recent earthquake has a green placemark / flag on it.
