Very powerful, try to avoid.
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.
Local residents Chris and Viv Young look at damage caused by the earthquake, along State Highway One near Ward on New Zealand’s South Island.
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 on September 30th, 2016, leading to the evacuation of 350 people from surrounding villages.
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 rockfall following the Christchurch earthquake in New Zealand in 2011.
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?
Residents walk through rubble in central Italy.
Central Italy has been hit by a magnitude 6.2 earthquake, only seven years after a similar devastating quake in the region.
Cataclysmic natural disasters frame indelible human stories.

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.
A satellite image of the 2004 boxing day tsunami striking the southwestern coast of Sri Lanka. Could a similar tsunami hit Australia?
Australia is surrounded by ocean, so is not immune to the effects of tsunamis. But how significant is the risk?
Sampling is a powerful scientific tool - when it’s used honestly.
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.
The village of Agoudal in Morocco’s High Atlas Mountains is home to a rare treasure.
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 early Earth may have been shaped by asteroid bombardment.
The discovery of the second oldest known asteroid impact site in the world can give us tantalising hints of the Earth's early crust.
Seven Sisters in East Sussex.
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.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core.
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…
Those tiny streaks sometimes land, and they can tell us a lot about the sky.
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.
The recent earthquakes in Japan and Ecuador were large, but were they connected?

When two major earthquakes occur within days of each other thousands of kilometres apart, it can look like they're connected. But are they? Here's what the science says.
The idea that the dinosaurs were wiped out by a giant asteroid was ridiculed – until the remains of a giant crater were found deep underground.
