Solar Tsunami: Frequently asked questions:
What is Solar Tsunami?
Technical name is “Fast-mode Magnetohydrodynamic wave (MHD wave).” During Solar Tsunami (Coronal mass ejection), hot plasma and magnetism erupt in a giant wave format. During this Tsunami, millions of tons of gas will be sent into space at a speed of 250 kmph to a height of even 1 lakh kilometres with high energy.

When was Solar Tsunami first observed?
Solar Tsunami was first spotted in 1997 by NASA’s Solar and Heliospheric Observatory. But, this Tsunami was observed by NASA’s Solar Dynamics Observatory.
What will be the speed of coronary emission?
Maximum speed of this Tsunami is mind-blowing. It can even attain a speed of 15 lakh kilometres per hour and can reach earth from Sun in just 4 days.
What will happen?
On August 4, solar magnetic eruption may enter into earth’s magnetic field. Due to collision with nitrogen and Oxygen atoms, a magnetic storm will be formed over earth. People in some countries (Canada & North US) can observe wonderful scenes in the dark sky.
What is the duration of solar magnetic cycle?
11 years
Any threat to us?
Solar Tsunami will not cause any deaths on earth. Britain may face communication and power problems. Other countries may need to prepare for short term communication problems.
