You get into the question, "What do you mean by 'immediately?'" The US Geological Survey monitors seismographs throughout the continental United States and studies the readings in an attempt to understand and hopefully one day predict earthquakes and volcanic eruptions. Nuclear explosions are one source of "background noise" that they need to understand and filter out. Intelligence gathering is a secondary function. They probably can look at the data and say, "Oh! That looks like a nuclear explosion!" and then pass it on to nuclear experts elsewhere in government, who then look at the details more carefully and tell you things like the yield and what not.
Different sorts of geological disturbances create different sorts of wave forms. Some waves are transverse waves, others are compression waves. From what I've read, underground nuclear tests tend to create a much stronger compression component than transverse components, due to the way in which they displace the earth around them. Tectonic shifts, on the other hand, creates much more of a transverse wave as the plates grind together.
All this sort of analysis is a sort of "after the fact" analysis, probably not done in real time, and it doesn't necessarily influence military operations so much. It's interesting to intelligence services because it influences policy and shapes the higher level decisions whose trickle down effects might be important to a military commander, so no, I don't think it ought to be included in Command.
After Fat-Jim's toy test had shaken the world and spread his news of the 'glorious achievement', I wonder how US intels can immediately gather and receive the strength of underground nuclear test by just reading the earthquake?
Besides, should CMANO also have an indicator/sensor or some short when earthquake, or familiar geological anomalies is happening? Something to tell player the artificial 'Act of God' is really comes to play, and warn them the estimated strength of nuclear blast.
