The first panel is similar to the events of 557: Students.
In the last panel, Black Hat describes having dreams where he receives specific information about the real-world, which seems closer to prophesying or precognition than what would be considered a normal dream, as normal dreams do not tell the future 
Based on his mannerisms, we can safely conclude that Beret Guy has stolen Black Hat's signature headwear.
In the title text, either Megan or Ponytail is responding to black hat when they are interrupted by a the first part of geographic coordinates- Latitude 35. 35 degrees North would include 31 major cities around the world, including 11 in Japan and 8 in the USA; the only major city within 35 degrees South is Canberra, Australia. This suggest an earthquake would happen soon in one of those major cities. The second half of the coordinates are most likely cut off to add uncertainty to the situation.

[Megan, Ponytail, and Black Hat are standing around]
Megan: I've been out of school for years, but I still get those dreams where I have an exam and didn't prepare.
Ponytail: I think that's one of those weird universal dreams- like forgetting your clothes or discovering rooms in your house you didn't know about.
Black Hat: Yeah! Or when you're having a normal dream, but then a horse appears on a distant hilltop, and it means that the dream is about to turn bad!
Ponytail or Megan, off screen: I... What?
Black Hat: I have that one like every night.
Black Hat: Or those ones where you're talking to someone, and they start repeating a latitude and longitude over and over, and then you wake up that morning and there's an earthquake there. Haha, dreams, right? So weird!
