There’s a shift happening in Earth’s outer core, as seismic wave data has revealed
Most of our knowledge of what lies at the center of our planet comes from studying seismic waves from earthquakes. Careful analysis of these waves can reveal the composition of rocks and metals beneath the Earth’s surface. A new study of seismic waves propagating from two different earthquakes – in similar locations but separated by […]

One of the hot, dense drops deep within the Earth has been revealed thanks to new imagery
For the first time, scientists have looked at an ultra-low speed zone. These enigmatic rock pockets lie near the Earth’s core, about 3,000 kilometers (1,864 miles) below the surface. At this depth they are obviously difficult to study, but we know they are there because of the way seismic waves pass through the Earth. These […]

The ‘monster’ earthquake on Mars is the largest ever recorded on another planet, according to NASA
In terms of seismic events on the Red Planet (or any other planet besides Earth), this is the largest recorded to date: NASA’s InSight lander recorded a “monster” of an earthquake, which is estimated to have reached magnitude 5. on the scale used on Earth. This beats the previous record holder, a magnitude 4.2 earthquake […]
