I can't see how an earthquake could trigger bass into feeding. The event in itself lasts less then a minute. If anything I would think it would "spook" them and shut them down.
Things like you mentioned... wind, moon phase, sunrise and sunset take place over hours. Those things effect light penatration ( yes i said penatration) which inturn effect fishing. An earthquake is too short of an event and does not effect light penatration (3x in one post)
