2. To cause (or help) to leave or withdraw from.

   “The firefighters decided to evacuate all the inhabitants from the street.”

Hence: “Passenger plane catches fire at South Korean airport. All 176 on board evacuated” → “[A] passenger plane catches fire at a South Korean airport. All 176 people on board [were] evacuated [from the plane]. ”

Note that in the linked Wiktionary entry, there is an attested usage from 1943. It isn’t exactly youth slang. It is, however, the sense with the most recent attested usage among all of those listed.
