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.

Finite difference methods have become a cornerstone in the simulation of seismic wave propagation, providing a robust numerical framework to approximate the differential equations that govern seismic ...

BUTTE, Mont. — Envision this scenario: You are going about your day. All is calm and quiet until suddenly, the ground beneath your feet begins to shake, and items within your home or workspace begin ...

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 ...

For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface ...

The first studies of the 28 March 2025 magnitude 7.8 Myanmar earthquake suggest that the southern portion of its rupture occurred at supershear velocity, reaching speeds of 5 to 6 kilometers per ...

Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft flying far overhead, research by University of Alaska Fairbanks scientists shows ...
