Large-scale natural experiments such as oil spills, tsunamis and climate change are things you wouldn't want to do on purpose. But that doesn't mean they're not scientifically useful experiments too.
Amatrice's still-standing ancient clocktower has become an iconic image from last week's deadly earthquake. But it is not the only unusual survivor.
Yesterday's earthquake in central Italy has resulted in many deaths. But it is not the earthquake that claims victims but our built infrastructure. Why is this so?
Scientists in Japan have discovered a way to 'hear' storms on the other side of the planet and use them to study the Earth's crust.
There are already early warning systems for earthquakes, but advances in seismology provide hope that experts will be able to predict when new ones will occur.
Central Italy has been hit by a magnitude 6.2 earthquake, only seven years after a similar devastating quake in the region.
Australia is surrounded by ocean, so is not immune to the effects of tsunamis. But how significant is the risk?
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.
Expect $33 billion of damage ... and that's just for starters.
Over 8,500 were killed in the 2015 Nepal earthquake, so how is the country coping?
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 earth around you might seem static but it's constantly in motion. We need to track this motion in fine detail if we're to keep our GPS networks up to date.
The destruction wrought by two earthquakes in Nepal opened up a major opportunity for child traffickers.
The nuclear operator was nowhere near adequately covered for the disaster. And it's not just a Japanese problem.
Scientists are setting Japan on the road to recovery, using data to protect against future disasters.
Christchurch is still reeling from the 2011 earthquake, but there may be more on their way.
The 2011 Japan tsunami illustrates how more marine creatures are crossing the oceans than ever before - and not all of them are friendly travellers.
Our climate is changing. But many of the devastating repercussions are little understood.
There was something unusual about the 2011 earthquake which caused so much damage in Japan. We should now look at other risk zones to see if something similar could happen there too.
Since the last earthquake in the region in 2005, we have got much better at recovering from disaster.
