The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Geophysics has shown that precise measurements and a little modeling can perform wonders, like showing us the detailed structure of the Earth’s interior despite the fact that it is inaccessibly buried ...

How can we determine how empty or full the soil reservoir is in areas that are difficult to access? Researchers have now demonstrated an elegant method to track groundwater dynamics in high mountains: ...

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had ...

Large earthquakes in densely populated areas can be deadly and very damaging to the local economy. Recent earthquakes in El Salvador (magnitude 7.7 on January 13, 2001), India (magnitude 7.6 on ...

It's only in the last few years that scientists have been able to map the red planet's interior structure. That's because ...

The data collected with the InSight lander revealed properties of the Martian core that could indicate why it is unfriendly to life. When you purchase through links on our site, we may earn an ...
