Moon Too Sees Quakes like Earth
Like our planet Earth, our natural satellite Moon also sees quakes in the similar way like earth. Recently Saumitra Mukherjee, Professor of geology and remote sensing at School of Environmental Sciences and Remote Sensing at Jawaharlal Nehru University, and her student Priyadarshini Singh reveal this overwhelming fact about the moon. The teacher-student duo found this incredible information by observing the photos sent by Chandrayaan-1, which is India’s first lunar probe.
Chandrayaan-1 was launched by ISRO in the year 2008, October. Its main purpose is to get a 3-dimensional image of the moon and mapping of its chemical composition.
Professor Mukherjee and his student observed this image taken by Narrow Angle Camera and Lunar Reconnaissance Orbiter Camera of Chandrayaan-1. From the pictures of the south pole of the moon, they found that the moon is also composed of several tectonic plates. Movements of these tectonic plates are the reasons behind the quakes in the moon land.
Professor also said that right now there is no established method to know and predict moonquakes. However, after studying the images of the quakes in the moon and comparing them with the Earth model will help to understand and predict the quakes in the moon.
“Tectonic plates at surface move due to mantle layer of Earth’s core and the movement of tectonic plates on Moon establish that some material in liquid form is present under its surface too,” he said.
Space Application Center in Ahmadabad helped Professor Mukherjee in this study. They assisted in deciphering different images and data in the most efficient manner.
The researchers published their study in the journal Nature India, IEEE Geoscience and remote sensing letters and Frontiers in Earth Science.
However, scientists are not finding moon-quakes for the first time. In 2009, NASA’s Lunar Reconnaissance Orbiter Camera (LROC) was able to send photographs of the moon that said that there are thin valleys. These valleys are called Graben. The scientists of NASA found from these images that the Moon observed tremors around 50 million years ago.
Isn’t it a great finding by the scientists?
