"I felt it" reports:
Upolu, Samoa / not felt: I didn't feel the quake. But since yesterday we have high waves and no difference between high tide and low tide. The ocean is coming unusual high up to our bungalows. One wave was like a tsunami and detroyed a part of the beach equipment, like the pool, some chairs and a stair on the beach.
Pava’ia’i, American Samoa / MMI V (Moderate shaking): I was asleep and the earthquake shook my bed and woke me up. It lasted for maybe 5-10 seconds but strong enough and long enough to wake me up.
