The activity of the sun can lead to earthquakes, and now we know how: Sciencealert


On a dynamic planet like Earth, it may be easy for drivers of change to pass without anyone noticing – but scientists have now created an unexpected link between the sun and the home world.

Solar spots, thus solar activity, caused a seismic activity, according to a team led by Matheus Henrique Junqueraa Saldanha from the University of Tsukuba in Japan. Their new research reveals how.

“The solar heat drives the temperature changes in the atmosphere, which in turn can affect things such as the properties of rocks and underground water.”

“Such fluctuations can make rocks more fragile and prone to breakage, for example – changes in rain and melting ice can change pressure on the boundaries of tectonic sheets. While these factors may not be the main motors of earthquakes, they still play a role that can help predict seismic activity.”

There is a lot happening here on Earth. Our planet contains an interior covered with a peel divided into separate sections and active weather system. There are many potential players of huge shifts in the planet's shell that may lead to an earthquake.

We are not good in predicting seismic activity. There are simply many variables, and the process that leads to a long and complex earthquake or earthquake.

However, knowledge of the operators means that we can better assess the possibility of the earthquake activity, and retract potential early warning signs.

Junqueira Saldanha and his colleague, Applied Mathematics Yoshito Hirata of Tsukuba University, identified, in connection with the activity of solar spots and the earthquake activity in a paper published in 2022. But it was not clear.

One of the hypotheses was that the heat may have to do with it.

Solar spots wax and fade with cycles of solar activity that are related to the opposite of the magnetic field of the sun. The maximum solar energy – the point at which this reflection occurs – is the time of the outbreak of solar activity, and the increase in solar radiance due to torches and other solar mystery attacks also creates a small temperature increase, about 0.1 to 0.2 ° C.

In Follow -up Research, Junquera Saldanha, Hirata, and their colleagues investigated the possible temperature relationship. They added to their model, including the records of solar stain activity and the temperature records of the Earth's surface, and make mathematical and accounting to see if they can create a relationship.

Their results showed that adding the surface temperature to the mixture improves the accuracy of their earthquake predictions-especially for shallow earthquakes that arise in the upper shell of the planet, instead of this deepest deepest that the scarf drives.

Since this is the layer of the planet most affected by the atmosphere and the water cycle, it is logical that the changes in this will affect the upper crust strongly, the researchers say.

This discovery highlights the complexity of our planet, as well as its relationship with our life star. But it also gives us another tool to add it to the growing variable set for the seismic prediction models.

“It is an exciting trend, and we hope that our study will shed some light on the largest image of what leads to earthquakes,” says Junkerra Saldan.

The research was published in chaos: a multidisciplinary magazine for non -linear sciences.
