Rarotonga's mini-tsunami after Japanese quake

The terrible Japanese earthquake and tsunami caused a tsunami alert here in Rarotonga.
The first wave from the huge 8.9 magnitude quake reached Rarotonga at about 8am local time but Rarotonga's small size, shape and surrounding reef means that usually tsunamis pass around us without generating big waves.
As this video shows, we had fairly low, non-dangerous rises and falls in sea level that continued for some time - this video was taken at about 10.30am.
Our little paradise is truly blessed.
