"I felt it" reports:
金武町  屋嘉 2792 - 1 (275.3 km S from epicenter) [Map] / MMI IV (Light shaking): I was sitting on the balcony (6th floor) when it started. Started with a light shaking and increased within 5 - 10 seconds to stronger shaking. Went into the apartment and all glassware was rattling. After that it became less, but the glassware was still a bit rattling for further 10 seconds. I estimate that the whole earthquake had a duration of 30-40 seconds.
