Africa’s physical landscape is not a permanent fixture and is being constantly shaped by massive geological forces.
Seismologists use sensors to build images of the interior of the earth. Making the invisible, visible.
In the field studying the rock association in the Doolena Gap greenstone belt, 30 km north of Marble bar in the Pilbara region of Western Australia.
The remote Pilbara region of Western Australian formed many billions of years ago when the Earth was much hotter and the crust softer than it is today.
Tides are the largest they have been for 250m years.

Fresh earthquakes and aftershocks hit parts of Papua New Guinea following February's deadly quake. It's Australia's slow push north that's part of PNG's seismic activity.

The Nov. 12 earthquake wasn't centered on any known major faults in the Earth's crust. In its wake, scientists will collect data to add detail to what they know about seismic activity in the area.
The new map was created using data from rocks found in locations including Madagascar.
You would not recognise Earth if you saw it 500 million years ago - the lands, oceans, climate and life were all very different. Scientists now have a new map of the deep history of Earth.

We know much about the true shape of our planet is thanks to two satellites that act as targets for lasers fired from Earth.
Up a bit, right a bit – Australia is always on the move.
Australia is always on the move thanks to continental drift which means the mapped coordinates of any place can get out of line with any GPS locating system. So what's the plan to fix it?
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.

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.
Some of the Earth’s fault lines between tectonic plates in the East Asia region.
Earth is the only planet in our solar system with both plate tectonics and life. Is there a connection?
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 Earth’s surface is in a constant state of motion, before, during and after earthquakes.

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.
Many marine reptiles like this nothosaur went extinct at the end of the Triassic, one of five major mass extinction events on Earth.
A fall in vital trace elements in our oceans could be one of the driving forces behind a number of mass extinction events during Earth's history.
Piton de la Fournaise or “Peak of the Furnace” on Reunion Island is one of the world’s most active volcanoes, shown erupting in August 2015.
What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
The cycles of nutrients into the oceans following the building of mountains may have been a prime driver of evolutionary change.

The rise and fall of the essential elements for life could have influenced the way life evolved over many millions of years.
Surface measurements hint at what’s going on within.
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.
Volcanism, driven by plate tectonics, built Earth’s atmosphere to make a habitable planet.

How is it that Earth developed an atmosphere that made the development of life possible? A study published in the journal Nature Geoscience links the origins of Earth’s nitrogen-rich atmosphere to the…
