Indeed. And it's actually fairly easy to find a lot of them. Many times an NPC who needs help with an event will try to contact you (they'll do a chat emote at you asking you to talk to them). If you're used to other MMOs this may just seem like a trivial gesture, but this is actually because the NPC wants your help with an event. So if you talk to the NPC it will either start a new event or point you to one already ongoing.
Also, once you finish an event don't run away immediately. Often once an event ends the NPCs involved will have a conversation and a new event will start after they're done talking. Sometimes they require you to follow them as well to start the new event, but they'll usually say so during the conversation.
