In Europe
Chicago is not on a fault line so there can't be earthquakes.
Earthquakes happen when the Earth's crust shifts violently. So if we know that an earthquake has happened in California, then scientist know that the crust under California is unstable, therefore making earthquakes more likely to happen there. Earthquakes can happen anywhere, but the tend to happen repeatedly in certain spots
San Francisco
most likely, yes Well - another earthquake can certainly happen - but - being linguistically precise and picky, another earthquake can't happen AGAIN because it has not happened yet. Not sure if this was the questioner's intent, but an interesting riddle none the less.
mostly likely
Along the San Andreas Fault in California is one likely place for an earthquake.
In Europe

On February 10, 2010, Chicago experienced a 4.3 magnitude earthquake. So it does happen.
It's on a fault line
The answer is San Fransisco, California.
It will collapse .
