Seismic waves from cyclones reveal Earth's hidden secrets
Scientists have discovered that seismic waves generated by cyclones can be instrumental in studying the Earth's interior. They suspect that mysterious geological structures may lie hidden beneath our feet, and their research method will not only enhance understanding of our planet in the future but will also prove useful during space missions.
Researchers have managed to record an intriguing echo that could provide a wealth of information about the geological structure of our planet. According to Science Alert, scientists are examining oceanic phenomena to better comprehend Earth's geology. These microseismic waves, which occur due to the interaction between the ocean and the Earth's crust, can assist in uncovering hidden parts of the Earth's geological structure.
A new method for studying the Earth's interior
Hrvoje Tkalčić from the Australian National University explains that this research utilizes microseismic signals as an alternative data source for analyzing Earth's structure beneath Australia. Intense storms, like oceanic cyclones, produce acoustic energy that is strong enough to penetrate the planet. Studies indicate that after passing through the Earth's core, these vibrations weaken significantly, making them more challenging to observe.
Tkalčić, alongside seismologist Abhay Pandey, searched for these seismic waves using sensitive spiral sensor arrays in remote Australian locations.
Scientists successfully identified these signals in waters near Greenland and Newfoundland, stirred by winter storms.
Researchers assert that this new method of detecting signals through the Earth may also be beneficial for space expeditions and the study of other planets.
