what is the relationship between earthquake and sunspot

Some scientists have become aware of a correlation between sunspots and Earthquakes and want to use the sunspot data to help predict. However, it has never been demonstrated that there is a causal relationship between space weather and earthquakes. Indeed, over the course of the Sun's. According to them, a possible link between solar activity and earthquake year solar cycles, represented by the amount of Sunspots are correlated with the .

There doesn't appear to be any significant connection between the two graphs.

The solar portion shows the well-proven 11 year solar cycle actually it's a 22 year cycle with two similar halves. The earthquakes show much less pattern.

There are many fault systems on earth, and if you cherry-pick one like the New Madrid faultyou might found a correlation just by chance, but that have no statistical value, even less if no physical mechanism is proposed for such influence. But as you can see in the graph above, if we include all earthquakes, that correlation vanishes.

The solar cycle does indeed have some influence on climate - by changing the intensity of UV radiation, which in turn changes the properties of the upper atmosphere. The exact cycle of earthquakes can vary by hundreds of years, and there is still NO way to predict WHEN they will exactly happen with current technology. When enough people make enough predictions that a catastrophic event will happen, some will be right.

Here is a small sampling of past apocalyptic forecasts. You can see that most did not come true.

No link between solar activity and earthquakes

Again, this suggests a causal relationship between solar activity and atmospheric disturbances; something not seen in the earthquake data. The flare solar activity for 18 February top panel plotted against the corresponding changes in the ionosphere above Austria bottom panel.

But these are large-scale statistical studies. Would that then have any geological effects? Well, what is a solar flare exactly? So flares are essentially just that; increases in X-ray emission and sometimes gamma-rays.

There is, of course, increased emission from across the spectrum: The only solar emission that makes it to the surface is visible light that we can see with our eyes, and radio emission see figure below. So barely any of this X-ray light makes it through the atmosphere, let alone to beneath the surface to where earthquakes occur.

Similarly, CMEs are essentially clouds of charged particles which get deflected by our magnetic field and rarely make it to the surface. This shows the what wavelengths of electromagnetic radiation can penetrate Earth's atmosphere and what wavelengths are stopped by the atmosphere.

Do solar flares cause earthquakes? - The Sun Today with C. Alex Young, Ph.D.

Of course, there are more sophisticated data analysis techniques and correlation tracking algorithms available compared to that which I have presented here. So if you feel that my rather simplistic approach has failed to reveal a potential relationship between solar and geological activity, then I urge you to sift through the data for yourself. This is how science works, which is why I have included links to the pages where I obtained my data so you may repeat the experiment for yourself if you choose, in order to verify or refute my conclusions.

But simply noting that a solar flare and an earthquake occurred together within a short time frame does not imply that one caused the other. We continue to be asked by many people throughout the world if earthquakes are on the increase. Although it may seem that we are having more earthquakes, earthquakes of magnitude 7.

A partial explanation may lie in the fact that in the last twenty years, we have definitely had an increase in the number of earthquakes we have been able to locate each year.

This is because of the tremendous increase in the number of seismograph stations in the world and the many improvements in global communications. Inthere were about stations operating in the world; today, there are more than 8, stations and the data now comes in rapidly from these stations by electronic mail, internet and satellite.

This increase in the number of stations and the more timely receipt of data has allowed us and other seismological centers to locate earthquakes more rapidly and to locate many small earthquakes which were undetected in earlier years. The NEIC now locates about 20, earthquakes each year or approximately 50 per day. Also, because of the improvements in communications and the increased interest in the environment and natural disasters, the public now learns about more earthquakes.

According to long-term records since aboutwe expect about 17 major earthquakes 7.
