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.

In September 2023, researchers worldwide picked up a strange seismic signal: repetitive shaking every 90 seconds for nine days. Even stranger, it repeated itself a month later. Experts have ...

It all started when a wave swept across Oklahoma on June 24, just before 11:11 a.m. local time. It buzzed one seismometer after another, seeming to ping-pong hundreds of miles across the state ...

Earthquakes normally produce waves of so many different frequencies, the wave readings appear more jumbled. But the mystery waveform from Mayotte was a crisp zigzag, which repeated after steady 17 ...

As their names suggest, ULVZs slow down seismic waves, and scientists have known about these strange areas that tend to hang around hotspots, which are regions where mantle wells up through the ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU).

In order to determine the wave heights, Dr. Bromirski analyzed 90 years of seismic records archived at a lab that monitors earthquake activity at the University of California, Berkeley.
