A new project tracks earthquakes accidentally induced by human activity. It suggests the problem is bigger than some scientists thought.
Lightning strikes are powerful – but we haven’t had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
New research suggests how asteroids may have helped create conditions for life on Earth. But we shouldn’t get too carried away with the idea – yet.
Early analysis of the New Zealand earthquake shows it may be a complex event, involving several faults on the South Island.
New study suggests a 64km diameter body travelling at 15km per second created the Orientale Basin on the moon.
Mexico’s Colima volcano erupted a few days ago, reminding the local population of the danger posed by the country’s two active volcanos.
A new study of the 2011 Christchurch earthquake shows boulders from rockfalls fell much further than in earlier quakes that happened before humans arrived and changed the landscape.
An expert panel has announced that we truly are living in the geological era defined by humanity’s fingerprint. But is it as simple as that, and does it leave “Anthropocene science” open to attack?
Central Italy has been hit by a magnitude 6.2 earthquake, only seven years after a similar devastating quake in the region.
New research suggests a mythical flood in China really happened about 4,000 years ago. It’s the latest case of scientists matching ancient tales to actual local natural disasters.
Australia is surrounded by ocean, so is not immune to the effects of tsunamis. But how significant is the risk?
Some water researchers are ignoring the evidence offered by sampling if it doesn’t fit their preconceived notions. But science should always be honest and open.
High in the mountains of Morocco, scientists have discovered something remarkable and rare: a spot that was struck by two meteorites, possibly millions of years apart.
The discovery of the second oldest known asteroid impact site in the world can give us tantalising hints of the Earth’s early crust.
After the recent collapse of part of the Seven Sisters cliffs in Sussex there’s an increased awareness of the danger of rockfalls on Britain’s coast.
Closing the passage between the Atlantic and Pacific oceans strengthened the gulf stream and helped kick off ice ages.
Space research never stops and it seems neither do the surprises. On ABC Breakfast News I covered some huge results from the last few weeks. Be still my beating (magnetic) heart Earth’s magnetic field…
Hunting for meteorites in the vast Pilbara is hard work, but even a tiny speck can tell us a great deal about the sky billions of years ago.
As carbon dioxide emissions continue to increase, scientists are looking to the past.
