An earthquake generates a series of seismic waves that travel through the interior or near the surface of the Earth. There are four types of seismic waves. How will three identically engineered ...

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.

Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft ...

An array of seismic sensors deployed to capture aftershocks from the 2018 magnitude 7.1 Anchorage earthquake also collected distinctive signals from hundreds of flights crossing over Alaska.

Seismic sensors in Alaska captured distinct aircraft signals, enabling classification of 48 aircraft types and enhancing ...

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 ...

Stanford researchers have devised a technique that transforms the tiny tremors generated by the everyday hustle and bustle of city life into a tool for probing the subsurface of Earth A new technique ...

When a 7.9-magnitude earthquake struck central China's Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings ...

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 ...
