Today in history: Monday 14 November 2016 at 12.02am, a magnitude 7.8 earthquake struck 15km north-east of Culverden, North Canterbury, starting near the town of Waiau. It was New Zealand’s most complex earthquake ever recorded, with more than 20 faults rupturing. 1/3

Scientists have discovered two faults north of Wellington to be more active than they first thought – the latest finding in a long-running, painstaking effort to map the region’s incredibly complex seismic environment nzherald.co.nz/nz/faults-near…

175 years ago, today an M7.4 earthquake struck Marlborough destroying houses in the nearby valleys. Wellington & Nelson also suffered significant damage to brick and stone buildings, and many houses in the Wairarapa suffered chimney damage. 1/3

In which I attempt to explain different magnitude scales by using music as an analogy. Not sure if it worked.

A magnitude 6.0 earthquake with strong shaking has occurred at 9:14am on Wednesday 20 Sept. The earthquake was 11km deep and located within 45km north of Geraldine and felt widely throughout the Canterbury region. Read all about the quake here 👇 mtr.cool/nymgutuzdt #eqnz

Today in history: the M7.2 Darfield earthquake struck Canterbury in 2010. Buildings were damaged, some partially collapsed and masonry fell from historic churches. Roads cracked open and paddock fences and shelter belts were displaced horizontally by up to 5m. 1/3

We map felt reports to identify how widely and how strongly people experienced earthquake ground shaking. 🗺 From tomorrow you will notice changes to the felt report maps that we provide on our website. Read all about the changes here 👇

A deep M5.6 earthquake south-west of Whanganui has caused shaking across parts of the North Island and the upper South Island. We have received more than 20,000 felt reports. For more details on the quake see: geonet.org.nz/earthquake/202…

We have issued a NATIONAL ADVISORY: TSUNAMI ACTIVITY following the magnitude 7.7 earthquake near the Loyalty Islands. We expect New Zealand coastal areas to experience strong and unusual currents and unpredictable surges at the shore.

There has been severe shaking in Porangahau this morning with a M5.7 followed closely by a M5.3. Our team are still looking at this so the size/locations are currently preliminary. We will have updated information ASAP. #eqnz

Mw 7.1 earthquake near Raoul Island today. Reverse faulting at 50 km depth. Small tsunami (~20 cm peak-to-trough) recorded at Raoul Island. The earthquake was well recorded across the New Zealand seismic network.

swarms: geonet.org.nz/news/4JzNrNwt6… You can find our earlier blogs in the News on our website by selecting the Data Blog search filter.

A swarm of earthquakes has been occurring tonight south west of Kawerau, felt across the Bay of Plenty. We have recorded more than 40 earthquakes so far, the largest of which have been a M4.8 and M4.6. This swarm is in a similar area to swarms that occurred in 2018 and 2019. 1/2

She’s snoring and I can’t get to the coffee maker to refill my mug. Send help.

A M4.4 earthquake at Lake Taupō triggered around 1200 felt reports this afternoon. Light shaking was reported. We expect aftershocks in the coming days. For more detail, see geonet.org.nz/earthquake/202….

Mw 5.5 (ML 6.0) earthquake 46 km deep off the southwest coast of the North Island. Hard to tell at a quick glance where it sits relative to the plate boundary - have to have a closer look tomorrow.

Felt that one!

We can’t predict the exact time, place and magnitude of future earthquakes. But we can estimate the chance of future seismic activity. Me and @mcgerstenberger explain the hows of earthquake forecasting👇
