Like a piece of music, every earthquake has a coda – and it contains clues about what’s happening in our planet’s core.

Half of Ethiopia’s territory is prone to medium to very high landslide risk.
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.
The volcanic eruptions that bring diamonds to Earth’s surface are driven by ‘pillars of heat’ stretching deep inside the planet.
Beneath the floodplains of Arnhem Land lies a hidden landscape that has been transformed over millennia as seas rose and fell.
Since 2011, professional and amateur archaeologists in Cardiff have been unearthing prehistoric artefacts. But last summer, they began to discover something even more extraordinary.
Earth doesn’t just have an inner core. It also has an innermost inner core, a solid ball within the solid ball in the very middle of the planet.
Pluto has recently active icy volcanoes, that have erupted water ice.
Researchers are using modern forensic techniques to find the bodies of victims of civil conflict in Latin America.
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.
Mars’ core is larger and less dense than we thought.
When sea sediment melts inside the Earth, it helps tectonic plates slide over one another smoothly.
The study of neutrinos produced within the Earth’s interior provides a better understanding of the radioactivity of our planet.
Changes in the Earth’s magnetic field pose a great risk to electronic infrastructure.
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.
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.
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?
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.
