We also sampled drowned trees in a fault-dammed lake to date past earthquake(s)

I love this visualisation as it shows which nations dominated which categories at the 2026 Winter Olympics. We see Gold Medals only. The Norwegians dominate cross country skiing, the Dutch are fast on skates, the Germans love a slippery slope, the French boss the biathlon. Source: buff.ly/F5dmSAj

One of the best things you can do when life seems like a mess is to journal. Helped me in my teens quite a bit.

First-ever trenches opened on Pāpāwai Fault A team from GNS Science are hard at work investigating the potential hazards a recently discovered fault line could pose to nearby Wairarapa towns.

Hi. Yes, we look to find evidence of past large earthquake ruptures in the trenches. These would look somewhat like modern M 7+ EQ ruptures but buried by more recent deposits. We then try to date these paleo-EQs to provide some context for future seismic hazard

Out on the bed of former Lake Roto-a-Tara in Central Hawke'sBay, wondering why it's not flat...1863 eq ruptures be there #eqnz

I'm stoked to have delivered the Annual Art Deco science talk in Napier commemorating the 1931 Hawke's Bay quake and rebuild. #eqnz. This time focusing on the 1863 Waipukurau quake. Thanks also to @jhgurneyquakes.bsky.social for joining me

Last week trenching the northern Alpine Fault at Blue Grey River w/ @stef-eq-geology.bsky.social and @jameslagreca.bsky.social and friends looking for paleoearthquakes. Many sandfly enemies too

On February 3, 1931, a 7.8 magnitude earthquake struck Hawke’s Bay, causing a mass loss of life & leaving thousands injured.

The earthquake struck at 10.47am, leading to the loss of 256 lives - 161 in Napier, 93 in Hastings & two in Wairoa.

We remember this event 95 years ago today.
