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.
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.
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.
Imagine the Earth pulling everything it is made up of, all of its mass, towards its centre. This happens evenly all over the Earth, causing it to take on a round shape.
Scientists have uncovered a hidden tunnel left in remarkable condition at a now derelict prison in Bridgend, South Wales.
A new detector could work out what’s causing a heat flow from the Earth’s interior. It may even solve the mystery of what powers the Earth’s magnetic field.
From crossing a road to fracking for oil, everything has inherent risks. At best, we can only aim to agree that, on balance, they are contained and justified.
50 years after the Moors Murders, UK police are still hoping to find a missing body. And scientists are working hard to help.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
Fifty years on from a groundbreaking paper, geophysicists have progressed from believing continents never moved to thinking that every movement may leave a lasting memory on our planet.
It takes more than a quick scan for high-tech archaeology to reveal history’s secrets.
Advances in computer power mean archaeologists can now tell a huge amount about what’s underground without picking up a spade.
Cleo Loi was an undergraduate when she made a startling discovery. Her story shows how brilliance, dedication and imagination drive science.
What led to the second major earthquake to hit Nepal in less than a month?
