The idea that scientists could warn a region that a big quake was coming at a certain time – with enough advance notice for large-scale preparation and evacuation – remains a dream, not a reality.
The Turkish government was well aware of earthquake-resilient construction techniques.
At least 1,700 people are thought to have died.
Using space imagery can help guide relief efforts to critical areas during a natural disaster.
Earthquakes originating underneath the ocean are often accompanied by tsunami warnings. Here’s what determines the tsunami risk.
A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.
The Java quake was so devastating in part because it occurred so close to the surface.
Monitoring volcanoes is a bit trickier when they’re deep under the ocean’s surface.
Many Victorians claim their cat or dog was acting strangely before yesterday’s earthquake. And while there’s no real evidence animals can predict a quake, they may be more sensitive to very tiny ones.
When will the next earthquake come? We don’t know, but that doesn’t mean we can’t get our cities ready.
A largely hidden fault beneath the Victorian Alps has triggered a magnitude 5.8 quake that was felt as far afield as Sydney, Adelaide and Launceston. Here’s what we know so far.
The geological record tells us we have had earthquakes in Australia’s deeper past much larger — possibly up to and bigger than magnitude 7.0.
8,000 tonnes of molten iron solidifies in Earth’s inner core every second – but it’s not distributed equally.
Mars’ core is larger and less dense than we thought.
Aftershocks of a major earthquake can continue for years or even decades.

Earthquakes can be caused by human, or seismic, activity. Is South Africa adequately prepared?
California was thought to be an exception, a place where oil field operations and tectonic faults apparently coexisted without much problem. Not any more.
We might not be able to predict the next big earthquake, but we can make sure we’re ready for it and understand the risks.
A big dip in the Earth’s crust may record an ancient continental collision from the dawn of plate tectonics.
