Solar Superstorms: the end of the Internet (and other communication concerns ...) from 2023?

Was COVID a joke given what awaits us?

A massive solar storm could impact the submarine cables that connect the continents. The Internet could therefore disappear if these cables are cut.

Solar storms are frequent but often have no impact on our electrical installations. Yet in the study presented by Sangeetha Abdu Jyothi of the University of California, this would be a super-storm that could have long-term consequences.

From the Solar Superstorms article: "Planning for an Internet Apocalypse", a Coronal Mass Ejection (CME), better known as a storm solar, is a directional ejection of a large mass of highly magnetized particles from the sun. When the earth is in the direct path of a CME, these magnetized and charged solar particles will interact with the earth's magnetic field and produce several effects.

The consequences of this kind of event would affect several areas: transport, GPS, satellites, electromagnetic technology and, above all, the Internet. It is the submarine cables that underpin the global Internet and the satellites around the Earth that could be damaged. They would risk cutting off at the source and therefore rendering those who resisted unusable.

Internet disappearance within a few years?

These historic storms have happened three times in recent history. The risk of this happening is estimated to be 1,6 to 12% per decade. In her study, the researcher identifies, for example, the Carrington event in 1859, during which the needles of the compasses oscillated in all directions, the telegraph lines were impacted and the northern lights were visible in Colombia ... There is also the 1989 solar storm, which took Hydro-Quebec's grid out of service and caused a nine-hour blackout in northeastern Canada.

The end of the current solar cycle is expected by 2023 or 2026. This study tends to show that a major event could occur at the end of this cycle, and therefore perhaps a super-storm.

In the study, it is shown that the links between the United States, Canada, Europe and Asia are very vulnerable.

New Zealand would lose all long distance connectivity except with Australia.

South Africa would maintain connectivity with the eastern and western coasts of Africa.

What solutions to avoid the disappearance of the Internet?

The researcher offers some solutions to prevent the Internet from disappearing following a massive solar flare. For example, new data centers should be built more geographically spaced from each other. The researcher also points out that electrical isolation mechanisms could be installed in places where submarine cables are buried ...

I don't believe a word of it. The submarine cables are protected by sea water. If they were to have problems, then the entire aerial network would already be completely dead.

I made exactly the same remark ... but I did not look at the study in detail ...

Perhaps it is their length that makes them more sensitive and that they are not 100% underwater ...

I don't know much about telecom ...

I made the same remark at the beginning but I still said to myself that experts must have thought of such a simple trick anyway : Mrgreen: . And in fact the paper seems to me to be quite relevant. First the cables are fiber optic, so it is not the currents in the cables that develop directly, but the repeaters installed at regular intervals to re-amplify the signal are the problem. These run on electricity, and are powered by current and connected to earth as a neutral. However, the article explains that the electric wave produced by a solar flare is made in the earth itself, it is the potential of the neutral which serves as a generator. Seawater only cuts high frequency waves but it conducts at low frequency, so it helps conduction and it's worse in the seabed
Note that seawater has high conductivity [26]. The presence of highly conductive seawater over more resistive rocks increases the total conductance of the surface layer [27]. Hence, the ocean do not reduce the impact of GIC but increases it.


The article looks pretty well documented. In fact obviously the internet network is far too young to have been tested in the face of this kind of event, especially since the sun has been rather calm since 2000 ...
