Unveiling Earth's secrets: Cyclones aid in seismic discovery
Scientists have discovered that seismic waves generated by cyclones can aid in the study of the Earth's interior. Researchers suspect that mysterious geological structures may be hidden beneath our feet, and their method will enable the study of not only our planet in the future but will also prove beneficial during space missions.
Scientists have managed to record a mysterious echo, which could provide us with a wealth of information about the geological structure of our planet. According to the portal Science Alert, scientists are examining phenomena occurring in oceanic waters to gain a better understanding of Earth's geology. It is these microseismic waves, arising from the interaction between the ocean and the Earth's crust, that may help in uncovering hidden aspects of Earth's geological structure.
A new method for studying the Earth's interior
Hrvoje Tkalčić from the Australian National University explains that this research utilises microseismic signals as an alternative data source for analysing the structure beneath Australia. Intense storms, such as cyclones over the ocean, generate acoustic energy strong enough to penetrate the planet. Studies show that after passing through the Earth's core, these vibrations become significantly weaker and more challenging to observe.
Tkalčić, along with seismologist Abhay Pandey, searched for these seismic waves using sensitive spiral sensor arrays in remote parts of Australia.
Scientists succeeded in identifying these signals in waters near Greenland and Newfoundland, which were stirred by winter storms.
Researchers suggest that this new method of detecting signals through the Earth may also be useful during space expeditions and the study of alien planets.
