So the knowledge she had would have been limited to what the WoL knew and what the WoL told them.
Assuming the WoL knows all the side quest chains, the stuff they were actually told about the Calamities from my recollection...

1-3: Absolute zip-nothing.
4: Earthquake caused when the Crystal Tower launched Dalamud, by Emet-Selch and Fandaniel. That sounds like a lot of info, but nothing actually useful for stopping it.
5: ???
6: Caused by the Elementals, probably. This is more just accepted public assertion rather than actually evidenced, but there's not much else around the War of the Magi that could've caused a flood like that.
7: This one we've got good intel on: the Dalamud drop, caused by Lahabrea with some distant aid by Emet-Selch, through the Seventh Legion. However, also remember that this Calamity didn't actually cause widespread destruction on the Source, thanks to the actions of--hold on this might be important--a group of Hydaelyn worshippers.

So we don't have anything useful about most of the Calamities, and the only one we do have actionable info on... well, she might've already acted to lessen the impact.
