Our new research predicts how Hunga Tonga’s vast underwater eruption in 2022 will change winters worldwide for years to come – as far away as Australia, North America and even Scandinavia.
For decades, scientists have tried to uncover the cause of long-term changes in Earth’s biodiversity. New simulations point at geography playing a critical role.
Research on the Deniliquin structure points to an asteroid impact that would have been more than double the scale of the one that killed the dinosaurs.
Since 2011, professional and amateur archaeologists in Cardiff have been unearthing prehistoric artefacts. But last summer, they began to discover something even more extraordinary.
Pluto has recently active icy volcanoes, that have erupted water ice.

Earth scientists are on the skilled occupation list for immigration even as universities cut back in this area. The problem lies with a funding model that offers no incentive to lift graduate numbers.
A network of sensitive instruments in schools around Australia is recording the eerie silence of the coronavirus pandemic — and tiny earthquakes that would otherwise be undetectable.
This unusual earthquake type generates an outsized tsunami.

A tricky kind of earthquake that happens in the soft rock of the ocean floor causes much larger tsunamis than their magnitude would predict. New research pinpoints a way to identify the danger fast.
Very rarely, depending on where you are in the world, your compass can actually point to true north.

Recently, magnetic compasses at Greenwich pointed directly at true north for the first time in 360 years. This is currently happening in Western Australia too. But what does it mean?
Sound waves let researchers visualize what’s happening below the surface.

Geophysicists use sound waves to build a picture of the magma and rock beneath this active volcano, most of which is underwater. It’s like CT scanning the Earth.
What’s going on 150 kilometers below the Earth’s surface?

A new array of seismometers provides a glimpse of what’s happening deep beneath this geologic fault. New data help explain why the north and south of the region are more seismically active than the middle.
An ERT survey line on the New Castalloy site: the metal pegs allow electricity to be injected into the ground and the orange cable carries the current to the pegs.

How can we find buried bodies? Ground penetrating radar is one solution - but it’s not always effective. Electrical resistivity tomography (ERT) offers a very sensitive alternative.
