中国地震局

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

国 = 囗 + 玉 : Mnemonic symbol: a nation's flag. Let's say the Chinese flag.

In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.

地 = 也 + 土 : Dorothy Gale (di) operates the excavator (也) in the space station's bathroom (Ø4) to move a pile of dirt (土) out of the way.

震 = 辰 + 雨 : James II of England (zh) is taking part in a game show. His task is to carry a birthday cake (辰) to the other end of the encampment's bathroom ((e)n4) while it is raining (雨) heavily and an earthquake (震) is shaking (震) James II of England and the cake. James II of England has to take care to cancel out the vibrations caused by the earthquake or his cake will collapse.

局 = 尸 + 乛 + 口 : Zeus (ju) got a job at the post office (局) just inside the space station's entrance (Ø2) and already at his first day a ghost (尸) approaches him. Zeus feels extremely threatened and tries to kill the ghost with a sickle (乛), but the sickle just cuts through the ghost. As the ghost is finally right in front of Zeus it produces a mandarin (口) which it wants sent to earth.
