Internet Cables Under the Sea Can Detect Earthquakes

Natural disasters are undoubtedly inevitable. However, scientists are working on systems that can at least predict such disasters with the technologies at hand. As a result of experiments that have been studied for many years, many systems have been developed. However, experts continues to look for alternative methods.

As you know, a study was carried out on Etna, Europe’s most active volcano. In this study, every place to examine the movements of the volcano surrounded by fiber internet cables. Now, a similar situation has taken place under the sea. This time, the researchers placed fiber cables under the sea.

Fiber cables, more cost-effective

It was stated that the cables placed under the sea to detect disasters such as earthquakes and tsunamis can act as sensors and will inform the possible situation in advance. With this study, experts, in addition to detecting disasters, It also aims to understand the change created by ocean currents.

Research, Run by the UK National Physical Laboratory (NPL) and partners. Experts tried the methods he developed with fiber optic cables in Canada and England. The technique is both cost-effective and cost-effective than permanent underwater earthquake sensors and eliminates the need for new equipment.

There are more than 430 fiber optic lines on the ocean and seafloor

One of the experts on the subject, Dr. Giuseppe Marra said, “Even though 70 percent of the Earth’s surface is covered with water, all seismic stations are on land. It is extremely difficult to place a permanent sensor underwater.” It is said that there are more than 430 fiber optic lines on the ocean and sea floors, and their total length exceeds 1.3 million kilometers.

in the journal Science In the published study, scientists found that light passing through fiber optic cables can change very little due to factors such as vibration, pressure change and temperature, which can be He noted that it can be detected with extremely sensitive instruments.

Commenting on the study, Dr. Mara, on the other hand, is about a 5,860 kilometer cable they used; “If we apply this technique to all cables on the seafloor, we can also we can turn it into a detector chain” he said. In addition, his explanations, “With these we can observe earthquakes, currents, and more. Extending our seismic network from land to the seafloor will reveal the Earth’s interior structure and its dynamic movements. will enable us to better understand.‘ he concluded.
