The earth pulsates: Our planet sends signals every 26 seconds!

The earth sends an hardly audible, seismic signal every 26 seconds, known as the "microceism". This discovery goes back to the 1960s and has employed scientists worldwide since then. A team of researchers has registered the signal with the help of seismographers, which are set up in various regions of the planet. How OE24 reports, the exact origin of the microsis ice is unclear. However, it was found that the signal does not come from earthquakes or volcanic eruptions.

A predominant theory sees the cause in the waves of the ocean. Strong waves that hit the continental Schelf could trigger pressure changes on the sea floor, which cause these slight vibrations. Interestingly, this 26-second signal is particularly clear during stormy seasons and suggests that weather conditions play a role. A second theory is discussed near the island of São Tomé, according to which a volcanic origin could be responsible for the signal.

Research on seismic activities

Seismologists strive to deepen their understanding of seismic activities. According to the Geo Research Center The goal of current research is to predict seismic wave patterns at inactive stations. For this purpose, new deep learning techniques are used, which enable data from neighboring seismic stations to analyze and determine the transmission function. The researchers aim to reconstruct data from offline or non -accessible stations in order to better understand the seismic events and the background noise caused by wind and weather.

The development of these methods is particularly important in regions with limited infrastructure, such as in areas with a few seismographs. Understanding the background of seismic activities can help to better predict future events and to recognize risks at an early stage.

Seismic background noise

The microseism is part of the seismic background noise, which is generated by natural processes such as wind and waves. Loud Spektrum.de Use geophysicists of this noise to analyze the inside of the earth. It is particularly exciting that despite the clear and targeted character of the 26-second signal, none of the current theories can ultimately completely explain the regularity and long-term constancy of the phenomenon.

Therefore, the microseism remains a fascinating puzzle for scientists who continue to work to decipher the secrets of the earth and their "heartbeat". Although comparable conditions do not produce a similar signal in other places, the microsis ice cream shows how complex the geophysical processes of our planet are.
