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

Despite advances in science, predicting earthquakes remains nearly impossible due to their deep origins, unique fault ...

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 ...

Something unusual is happening deep within Earth’s mantle,around 1,700 miles below the surface, where seismic waves accelerate in a way that has left scientists scratching their heads for decades.

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 ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical ...

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.

Seismometers measuring these two different types of seismic wave can help reveal the density and composition of the underground medium (such as water, or rock) through which those waves travelled ...

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.

In this case, the Rayleigh wave, a type of seismic wave that moves through the Earth’s surface, was detected 750 kilometers (approximately 466 miles) from the volcano. “Early warnings are very ...
