Readers posted comments like: "Never known Rotorua to be this bad which is a worry. What the heck is happenin?" and "Felt like a truck hit the house. The dogs went nuts."
From reading the comments you get the impression there was either a swarm of earthquakes or a huge fleet of trucks barrelling through Rotorua on Friday night.
Maybe the date - Friday the 13th - and the impressive yet spooky yellow full moon added to the sense of unease across the city as quake followed quake.
It certainly wasn't a night like any other lately.
Around the time of the ninth earthquake GeoNet tweeted the following: "If you are watching our website you may have noticed Rotorua is having another wee swarm. This is common in the area."

Indeed GeoNet's website shows there have been 4645 earthquakes in the Tongariro/Bay of Plenty region in the past year - more than 3200 of those registering above 2 on the Richter Scale.
But try telling locals freaked out by Friday night's quakes that this sort of thing happens all the time.
If anything, let's take it as a reminder to be prepared for an emergency, should next time prove something a bit stronger.
