Three earthquakes struck last night just north of Waiheke Island, but we only felt the biggest one. A sharpish jolt which sounded like some heavy object falling against the walls of the house. No shaking or rattling though, no pictures swaying on the walls or plates rattling in cupboards. No tsunamis either even though the quake was under the seabed.
It was quite surprising because it just happened instantly without any rumbling warning. The few previous earthquakes I have experienced here in New Zealand have been of the swaying kind, where the buildings I was in started swinging slightly from side to side, but not dramatically enough to move objects.
New Zealand's alternative name is the Shaky Isles anyway.
