Is there a way to speed up the blue questionmark encounters?

Once in a while blue question marks appear on the minimap. Sometimes they have blue circles on the world map¹ but sometimes there is no other clue except for the direction at all. and since the marker disappears within a few seconds, I very often even just have to estimate the range, making me spend multiple minutes of game time spending for figuring, in which area an event could have taken place.

Then, in the lucky case, my chase wasn't for nothing, I end up in an area, finding a trail in survival vision. These trails not rarely leading to nothing². I mean I expect there should be additional tracks to follow, but sometimes I can hardly if at all find them. Making me in the end having invested like 20~30 minutes of playtime for finding (if lucky) something like an ammo box in the end. So is there a way, like a specific pattern or something I am not aware yet to look out for, to finish these encounters within a few minutes³?

¹ I am not 100% sure if these 2 things are connected, since its irregular

² Well at least I find nothing.

³ As that's the maximum amount of time I'd be willing to spent on a track down that might reward me with an survivor but most often with nothing but crap my inventory is filled with already anyways.
