In September 2023, a global seismic mystery began to unfold. Every 90 seconds, the Earth pulsed with a strange, low-frequency ...

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird ...

These factors can locally intensify the seismic waves, therefore leading to additional damage. “In the 1906 California earthquake, some people living 100 miles away slept through the quake ...

These mysterious waves, known as PKP precursors, arrive just before a type of seismic wave known as PKP waves, which travel through the Earth during an earthquake.

As their names suggest, ULVZs slow down seismic waves, ... First, a brief explanation. There are actually many types of seismic core phases that traverse a specific ray path.

Seismic body waves, which travel through the planet’s interior during a quake, have so far provided insights into Mars’s core and mantle, but have revealed little about the crust away from the ...

In Mexico City in 1985, the frequencies of the seismic waves were crucial to understanding the damage caused by the earthquake. A team of American scientists concluded in a report published by the ...

Seismic waves provide evidence of ocean in Martian soil The InSight probe has recorded meteorite impacts and a Mars quake. An analysis of the data points to a water reservoir deep below the surface.
