Spending a semester with us is a great option for undergraduate students who study volcanoes but have never seen one erupt. Feel free to reach out with any questions.
Did you know that UH Hilo participates in the National Student Exchange Program? We welcome students from all over the upper 49 states to our campus every year. We also have a robust international exchange program.

If you are interested in learning about volcanoes with a front row seat, reach out!

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

The #HayliGubbi eruption came after a period of unrest that started in June-July 2025 with a large dike intrusion in the southern sector of the Erta Ale rift. Our InSAR study will be out soon but you can have a summary at the link below. @earth-science.bsky.social #geoscience

Colonization was like a powerful jigsaw ripping apart nations' families, shredding them into the darkness of a denied past. Now, Indigenous people work to rebuild the puzzle, reclaiming the tiny pieces of history scattered to the winds and reclaiming their identities, histories, and homelands.

On the Origin of Species was published on this day in 1859.

It really did change the world, and the way much of humanity views our place in nature.

What's the 2025 equivalent to a Walkman?

Mini-volcanologist is 8 and loves music and dancing to music. She has an Echo Dot at home, but it's reliant on Kids Radio. We want something portable she can curate and play her own music on. Not a phone.

At this age I was attached to my Walkman. Recs?

We think there was a small eruption there in July/August (at least a small plume) and some ongoing activity there since (including continued uplift). I suspect all linked to recent activity along dyke from Erta Ale (See COMET reports on July/August activity at comet.nerc.ac.uk/event-respon...).

Activity at Hayli Gubbi began in July when there was an eruption at Erte Ale. Magma propagated 30 km south passing under Hayli Gubbi. Since then, there has been a small plume, quasi-continuous SO2 emissions and uplift. Details in @uk-comet.bsky.social event response report: tinyurl.com/y3nfdfj8

An eruption from the #HayliGubbi volcano in #Ethiopia resulted in a large ash cloud, visible here from space. 🌋

This impressive view was seen 36,000km above Earth by our Meteosat-12 satellite on 23 November at 13:40 UTC.

Afar volcanism is known for its dyke intrusions and lava lake at Erta Ale, but here is an example of what looks like a pretty sizeable explosive eruption at a previously barely studied volcano, Hayli Gubbi 🌋🌋
An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.

The #HayliGubbi #eruption in Afar, Ethiopia, is the first documented eruption at this poorly known volcano.

Was it entirely unexpected?
Difficult to say - Berhe Goitom and colleagues already reported some seismicity in 2011-2012 so perhaps there was already some geophysical unrest for a while:

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.

Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

Study after study shows that using LLMs is bad for cognition, bad for learning, bad for understanding, bad for mental health. So why are our schools and universities still relentlessly pushing them?

3 yrs ago, I was nearly recruited to CSIRO, which at the time felt like a dream job. Seeing this total cleansing of scientific talent across 🇦🇺 (not just in CSIRO) is so shocking.

Politicians so rarely pay attention the value of scientific careers, but when they do, be sure to get that message home👇🏾
