How are geomagnetic storms caused?. Explain their effects on Earth.

Geomagnetic storm is a disturbance in earth’s magnetosphere. Their occurrence is influenced by solar flares emitted by the Sun. The increase in geomagnetic storms coincides with Sun’s 11-year solar cycle.

Formation

  • Solar plasma particles present in solar flares come in contact with earth’s magnetic field area known as magnetosphere.
  • This creates shockwaves that disturbs the magnetic field of earth for a temporary duration. Majority of the effect is directed towards polar areas.

Effects on Earth

  • Decline in magnetic field
    The geomagnetic storms can disrupt earth’s magnetic field strength. This lasts for about 6-12 hours and recovers gradually.
  • Risk on astronauts and pilots
    Astronauts and high-altitude pilots will be exposed to solar radiation. This radiation can cause many health related issues.
  • Communication system
    Radio communication, Global Positioning System and satellite communication will all be affected due to geomagnetic storms.
  • Power supply
    Outages can be caused in power supplies as a result of voltage surges due to altered magnetic activity. This is because of changes in magnetic field.
