Good morning #IAVCEI2025! I have two presentations for you today. I have a talk about the amazing acoustics of the Hunga eruption at 3.45, followed by a poster on the 2022 unrest episode at Taupō (which inc. a tsunami!) See you there!

The morning sunrise over the lake almost makes up for the lack of volcanoes in Geneva #IAVCEI2025

On the last leg of my journey to Geneva for #IAVCEI2025. Looking forward to meeting friends and learning new science!

Another photo from fieldwork on Friday. We were treated to awesome views like this while flying between spots: looking south over the Emerald Lakes, Red Crater, and Ngauruhoe, with Ruapehu poking out on the left. If you look closely you can see a few walkers on the Tongariro Crossing. #VolcanoMonday
View down over a barren, volcanic, brown and red landscape. In the centre are two lakes, one a deep emerald green colour, the other a cyan blue. Behind the lakes is a deep volcanic crater, and then behind that is a large red conical volcano. In the distance, a larger, snow dusted volcano is visible.

Always love a chance to do some fieldwork. This was the view from the top of Ngauruhoe volcano today, looking north over Tongariro with Lake Taupō in the distance.
A high view over a volcanic landscape, with arid mountains and grey valleys. In the car distance, a large blue lake can be seen. All under a massive blue sky with some high, wispy, white clouds.

Beautiful summer day in the Taupō Volcanic Zone today. Four active volcanoes can be seen in this view from Tauhara.
Expansive view from a tree covered mountain. In the middle distance, a large blue lake can be seen with a small town on the lake shore. In the far distance, tall rocky mountains with traces of snow can be seen. All under a cloudless blue sky.

Please bring out your best photos of birds looking straight into the camera! Sometimes they look goofy, sometimes they look intense.

A dapper looking Tūī I met last week while visiting the Coromandel. #birds
A dark bird looks straight at the camera. The feathers are iridescent with green and blue shades, plus white feathers on the neck look like a floppy white bow tie.

Queen of the Volcanoes.

I've always thought this explosion plume from Volcan de Colima in 2014 looked like a crown 👑 #VolcanoMonday
We are looking up at a conical volcano illuminated from behind by the morning sunrise. Atop the volcano rises a grey plume of cloud, shaped like a crown and fringed in gold colour from the rising sun.

Always an exciting day at work when I get to hop into a helicopter to go check out activity at Whakaari volcano. Here's the view into the crater from today.
Looking down at a rocky island dominated by a large crater. A thick, white, steamy plume rises from the centre of the crater.

Red hot lava drawing curves in the air after a small explosion at Stromboli volcano, 2016. #VolcanoMonday
Red arcs of hot lava curve upwards and outward from a glowing vent, hazy with volcanic gas.

This figure alone tells you the whole story. Those median regression lines make no sense. I cannot understand how stuff like this gets through peer review.

Kia Ora to all my new followers over the weekend 👋 I should probably reintroduce myself. I work on volcanoes by looking at volcanic earthquakes and sound waves. I also help monitor active volcanoes across Aotearoa New Zealand 🇳🇿
Yours truly standing in front of an erupting volcano in Iceland. Red hot lava can been seen spewing from a vent. Red hot lava erupting from Yasur volcano in Vanuatu.

If the plural for goose is geese, does that mean the plural for moose is meese? #AskingForAFriend

Stunning weather for my first day in Anchorage. I'm here for the #SSA24 conference, and I'm looking forward to meeting and learning what other seismologists have been up to!
View across a watery scene towards a city skyline, with the backdrop of high and snowy mountains. All under a blue sky with some clouds.

Gorgeous sunset over Taupō and the National Park volcanoes.
Sunset colours in a clear cloudless sky over a large calm lake. In the distance, a series of volcanoes in silhouette.

Good evening from Taupō, Aotearoa 🌋🇳🇿
Dusk colours over a large lake and the silhouette of volcanoes in the distance.

Today was a good day to be working in the field. View from Te Maari on Tongariro. ☀️🌋🇳🇿
Wide view over a sun draped landscape with lakes and forest covered hills. A wide volcanic crater fills the foreground.

Absolutely stunning webcam views of the sunsets over Taranaki, Tongariro and Ruapehu volcanoes earlier this evening. Almost like a Turner painting. ⚒️🌋🇳🇿
The silhouette of a perfectly conical volcano is framed by a sunset featuring pastel colours ranging from yellow, orange and blue. Silhouette of multiple volcanoes beneath a pastel blue sky at sunset, with orange and yellow shades on the horizon.

Another gorgeous summer day in Taupō. Always love that view to the volcanoes. 🇳🇿🌋⚒️
Beneath a blue sky streaked with wispy clouds, sits a sun drenched lake with volcanoes in the distance.

skjalftalisa.vedur.is is a superior (and official) website for exploring seismic activity detected by IMO in Iceland. Here's what the dyke activity looks like. One of the buttons in top right brings you to plots of lat/long/depth over time.
Map showing earthquakes as circles, coloured by time and sized by their magnitude. A clear NE-SW line can be seen where a magmatic dyke has intruded.

At Villarrica volcano in Chile, I always loved looking at the summit to watch the individual puffs of gas from the small explosions in the vent. Like a living, breathing creature. #VolcanoMonday 🌋
A snow covered conical volcano with black lava can be seen against a blue sky. Floating away from the summit are individual puffs of white gas.

A lot of people balk at the idea of getting up at 5.30 am to go rowing, but it's worth it for sunrise views across Lake Taupō to the volcanoes in the distance, just like this morning. 🌋🇳🇿
A view at sunrise across a calm and large lake towards snow-capped volcanoes rising in the distance.

Beautiful day to check on activity within Whakaari volcano. 🌋🇳🇿
A small island sits beneath a cloudless blue sky. The island has a large crater from which wisps of white steam rise.

Hey 👋 I'm Oliver and based in Taupō, Aotearoa New Zealand. I use earthquakes and sound waves to help understand the physics of volcanic unrest and eruptions 🌋

Here, have some nice warm oozy lava from Iceland #VolcanoMonday 🌋⚒️
