So Interference, under US order caused an earthquake in Omega city using technology she developed?

So the Omega league is going to try and figure out what's going on while saving people?

That's cool. I wonder what the US government is up to causing destruction to its own city?

Dr. Fang decided this was the simplest course of action and Harth has no idea she caused the earthquake.  She just wanted a big enough catastrophe to have the Omega League show up so Horizon can be seen doing good and join them.  If Harth is suspicious enough to carry out an independent investigation on the cause of the earthquake, Dr. Fang might get into some hot water.  Or he might just think it was a freak earthquake.
