I see a lot of different explanations online but I'm not sure if I understand the nuances correctly
From what I can gather:
仮定 is used when a situation is unclear and an assumption is made based on facts and logic
想定 is used when imagining a possible situation and assuming it happened
Considering this, I have trouble telling the difference between these sentences for example:
今,大地震が起きたと仮定したらまずどうしますか
今,大地震が起きたと想定したらまずどうしますか
I would like a more detailed explanation and if possible, some examples that show where one would be used and not the other.
