News - Earth experiences unexplained seismic tremors every 26 seconds

In 1962, Columbia University researcher Jack Oliver was the first to document the phenomenon called "Pulse of the Earth." This is a mysterious seismic pulse that our planet produces with the precision of a calibrated metronome every 26 seconds. The aforesaid researcher found that the source of these rhythmic tremors was localized somewhere in the South Atlantic Ocean. In the summer months, the intensity of these tremors increases, reports Planet Today. Two decades later, in 1980, the American geologist Gary Holcomb drew attention to this phenomenon again. He noted an increase in seismic resistance during hurricanes. And again that mysterious phenomenon was forgotten—for about 20 years. Then the "Pulse of the Earth" was revealed again. University of Colorado student Greg Bensen decided to study it. Bensen was assisted by his advisor, Mike Ritzwoller. The tandem talked about the first results of their research on Discover Magazine. Using a suite of state-of-the-art instruments, they were able to identify a more precise localization of the pulsation. The source was found near the west coast of Africa, on the Bight of Biafra. But they also could not understand the reasons of this mysterious phenomenon. What theories does the scientific community have? One theory suggests that this pulse is caused by waves hitting the continent and deformation of the ocean floor. Another theory is that volcanoes are to “blame” for this seismic activity.
