The internet, transit and telecommunications systems, base station and power grids could be shut down by a massive geomagnetic storm. These weather events happen when the sun ejects a large bubble of superheated fuel known as plasma. This bubble is called coronal mass ejection. It usually contains a cloud of electrically conducting protons and electrons. However, this won’t be the first time. On September 1 and 2, 1859, telegraph systems all over the world failed. The telegraph operators also received electric shocks, the telegraph paper caught fire. Now, according to a report from Space.com, new scientific evidence from Antarctic ice core samples suggests the geomagnetic storms cause induced currents to flow through the electrical grid. This also includes transformers, relays and sensors.
These storms will not only impact the internet, but are also capable of frying the delicate electronics on satellites into the sky. The storms are also expected to damage the digital and power connectors connected to them. The interruptions caused can last three to six months.
According to the Space.com report, it’s only a matter of time before Earth is hit by another geomagnetic storm. It shows how a Carrington Event-sized storm would be “extremely damaging” to electrical and communications systems worldwide. It can also lead to outages that can last for weeks. Storm, if the magnitude of the Miyake event hits, the results would be catastrophic for the world. The space weather warnings wouldn’t be of much use either.
In February, the Center of Excellence in Space Sciences (CESS) under the Indian Institute of Science Education and Research had said Earth would be affected by geomagnetic storms on the sun’s surface. The research institute’s models indicated that the potential for an impact on Earth was high, as the material is expected to whiz past at speeds of 21.60,000 kilometers per hour. It also said in a tweet that the impact was unlikely to be dangerous. It said moderate geostorms are likely. According to a report from spaceweather.com, the geomagnetic storms caused by coronal mass ejection would be G1 class and the explosion would peak in category C3, which is considered to be in the weak category.
