Perhaps have it inform you of a quake, but not alarm? So instead of "Warning: Siesmic Event Detected" (/Iminent/etc), have it just say "Siesmic Event Detected" (/Iminent/etc), or maybe just inform yopu with the "Siesmic Watch Initiated", but then not warn you when its iminent or when it occurs unless you have units near there?
Also, are the Savants perfect siesmologists / vulcanologists / meteorologists? I know humans can never get it perfect, so IF the Savants can also make mistakes with their warnings, perhaps add that when will say "Siesmic Watch Initiated" it may not eventuate into a quake because they got it wrong?
On the other side of the coin, if they are perfect meteorologists - can the plot their predicted path of storms/vorticies and even lava when they are detected? Just another idea.
As for determing a good location for a base/Outpost, perhaps have an overlay (ALA Sim City), showing you the severity/frequency of disasters (either overall or a particular disaster - ie you don't care if there's meteors when you have MD, and same for Eruptions when you got lava walls...)
