Any number of ways! Neji heads a part of morning training, can be found in the DOGS office, and he's often on the the outer wall of Death city at various intervals during the day, keeping tabs on things outside the city with Clairvoyance. Of course, Ed is free to request him at any given point as well~ :>

For the earthquake, he's using Clairvoyance extensively to keep tabs on everyone, the structural integrity of surroundings buildings, and searching for trapped souls.

So really, lots of options |D
