The Chrono Quake refers to a galactic calamity that rendered the usage of Chrono Strings and Chrono Space unusable. This in effect crippled space travel and long range communications and was responsible for bringing many civilizations to the dark Ages where entire space-faring civilizations rapidly decayed and died. Entire universes were found to have been destroyed due to its adverse effects.

While believed to have been an enormous natural disaster, the Chrono Quake was revealed to have been engineered and utilized by the Val-Fasq by usage of the Chrono Quake Bomb. The Chrono Quake was observed to have taken place two times, once to force out the inhabitants of ABSOLUTE and once to conquer the EDEN civilization. In Galaxy Angel Eternal Lovers, the third occurrence was stopped by the Moon Angel Wing.
