Why Does Earth Pulsate Every 26 Seconds? | Latest Seismology News

Why is Earth pulsating every 26 seconds, and why can’t scientists explain it after 60 years? This is an enigma wrapped in a periodically predictable mystery motion. It could be a harmonic phenomenon, a regular seismic chirp caused by the sun’s energy, or a beacon drawing scientists to its source to begin a treasure hunt.

In the early 1960s, a geologist named Jack Oliver first documented the pulse, also known as a “microseism,” according to Discover. Oliver, who worked at Columbia University’s Lamont-Doherty Geological Observatory at the time, heard the noise, but didn’t have the advanced instruments seismologists have now at his disposal.
