Leimatua Vavau (246.6 km E of epicenter) [Map] / Very weak shaking (MMI II) / horizontal (sideways) swinging / very short : I heard the noise for quite a long time before I felt the swaying. Because of the nose I was waiting for the movement and then felt it. The lights in the room swayed a little but the girl with me neither heard nor felt it | 21 users found this interesting.
