Incident
noun
An action that takes place that could change the locale or even the world has got to be a big incident. You'll sometimes see this on the ends of "incident" names, like the "Manshuu Jihen" (満州事変), aka the "Manshuu Incident." You know that it isn't an unusual or strange incident (like 変事) because the "strange" kanji (変) doesn't come first with this word. Instead, it comes after and means "change" in this case.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
