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.
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 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.
The 2011 Japan tsunami illustrates how more marine creatures are crossing the oceans than ever before - and not all of them are friendly travellers.
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.
A magnitude 7.5 earthquake has hit Afghanistan, with the effects felt as far away as India.
Ten years ago, a devastating earthquake killed tens of thousands of people in Pakistan. How has the devastated town of Balakot recovered?
Are you at risk from natural disasters? Research shows media reports could actually reduce people's perceptions of risk.
Earthquake monitoring can now detect a quake and warn people before it arrives.
Retrofitting old or cheap houses with earthquake protection is often expensive and laborious. What if we could save whole streets at a time?
The magnitude 7.3 earthquake that hit Nepal this week should be classed as an aftershock rather than a second earthquake.
What led to the second major earthquake to hit Nepal in less than a month?
Japan has the most powerful seismic network in the world. And this network is throwing out some warning signs.
Nepal has thousands of journalists working in hundreds of media outlets and publications. But getting the story out about the deadly earthquake was no easy task.
For seismologists, there's much to be learned after a major earthquake, as aftershocks help them map out the fault with high precision. More data now can prepare a region for its next big one.
Cloud computing has the potential to predict earthquakes based on animal behaviour.
The relationship between Nepal and the international development industry has long been difficult. But the work of Nepalese youth groups gives grounds for hope.
