Etna Volcano Surrounded by Fiber Cables: Why?

With the development of the internet in the 1990s, a large number of fiber lines were laid by Telecommunications companies. The number of these fiber lines was much more than the number needed to spread the internet, and companies used these lines. Investigation of earthquakes, land structures and even whale sounds.China started hiring.

Today, researchers have similarly started to study Mount Etna, Europe’s most active volcano. You know that Mount Etna is a very active volcano and It greatly affects the life around it. In the past months, we have mentioned that the volcano has erupted twice in a row. So how do researchers study the activity of this volcano using fiber lines? Let’s take a look at how this is possible.

Etna’s movements will be able to be informed about the activities through fiber cables.

We mentioned that fiber lines have been used for a long time to study earthquakes, make land surveys and even detect the calls of whales thanks to fiber cables laid underwater. Fiber cables work by carrying light pulses from one point to another, and when there is an interruption in these cables (for example, the cables can break in an earthquake), some of the light passing through the cable returns to the source. That’s exactly why researchers use fiber cables, too. even a small interruption or movement depends on what is affecting the cable or how far away it is. can provide relevant information.

For example; In the quarantine experienced during the pandemic, information such as how many people or how many cars were on the streets and streets could be obtained by using these cables. Now, a similar method will be used to detect the active activities of Mount Etna, which is seen as one of the most dangerous volcanoes of today. Researchers have discovered that the lava that it sprays from time to time causes many damage, from the crash of planes. He began laying fiber cables around Etna. The red and blue cables laid with this project, called DAS, and the returning light waves in case the volcano enters any activity, will provide researchers with information on issues such as the distance and magnitude of the activity.

These cables, which can detect anything down to the sound of a human footstep, can detect almost all frequencies, allowing researchers to learn about all possible activities. For so many people living around Etna, some relief from their life on the edge and It is hoped that much more successful results will be obtained than previous methods.
