The gravitational pull of the Sun and the Moon produces the tides, so it makes sense gravity could affect plate tectonics and potentially trigger earthquakes. In a solar eclipse, the Earth, Sun, and Moon are aligned, so you’d expect the effect to be greatest. Is there a correlation between eclipses and earthquakes? The short answer is yes, but it’s not really the eclipse that increases the probability, but the lunar phase.
According to the U.S Geological Survey (USGS), recent studies have indicated a correlation between high ocean tides and earth tides and earthquakes on shallow thrust faults and undersea subduction zones. In an earth tide or body tide, the Earth’s surface is displaced by the gravity of the Sun and Moon. An ocean tide works the same way, except it’s water that moves rather than land. Both types of high tides occur during the full and new moon. A lunar eclipse occurs during a full moon while a solar eclipses occurs during the new moon, but there is no statistical increase in seismic activity compared with any other new or full moon. If you stop to think about it, the alignment between the Earth, Sun, and Moon has to be very precise to produce an eclipse, but the bodies come close to that alignment relatively often.
During earth tides, the surface of the crust may rise or fall by a few centimeters. The affect of ocean tides is more pronounced. Ocean tides can change the sea level by over a meter, which changes the pressure on subduction zones and the faults near the edges of continents.
How significant is the increased risk? The USGS calculation estimates a 3x increased risk of an earthquake. While this may seem like a lot, the risk at any given time is extremely low, so multiplying it by three still yields an extremely tiny probability of an occurrence.
The semi-diurnal tides also have an affect on seismic activity and have been connected with aftershocks in volcanic regions. Even so, the chance of an earthquake occurring is the same whether it is day or night in the region.
There is a view that it is heat that can do it during the eclipses, the Earth cools down and then heats up and in fault lines and fissures this has an expanding and contracting effect, then there is; (I have another view regarding the eclipses and evidence that there is a cooling and heating effect and other constituents)

WHERE THE POWER GOES OUT: A solar superstorm can make your lights go out. New maps released by the USGS show where the power is most likely to fail: The Denver metropolitan area, the
Whether or not *your* power goes out during a solar storm depends on two things: (1) The configuration of power lines in your area and (2) the electrical properties of the ground beneath your feet. In areas of more electrically resistive rock, currents struggle to flow through the ground. Instead, they leap up into overhead power lines – a scenario that played out in
The new maps are possible thanks to Earthscope--a National Science Foundation magnetotelluric survey of the upper 2/3rds of the contiguous

SPACE WEATHER BALLOON DATA: Approximately once a week, Spaceweather.com and the students of Earth to Sky Calculus fly space weather balloons to the stratosphere over California. These balloons are equipped with radiation sensors that detect cosmic rays, a surprisingly "down to Earth" form of space weather. Cosmic rays can seed clouds, trigger lightning, and penetrate commercial airplanes. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias and sudden cardiac death in the general population. Our latest measurements show that cosmic rays are intensifying, with an increase of more than 18% since 2015:
Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep-space radiation.(Courtesy spaceweather.com)

From this we can deduce that sensitive people can feel shaky or whatever and also it effects the Schumann Resonance. There is also a discussion that the Planets of the solar system are having climate change which puts a doubt of just human made climate change.
RESEARCHERS PREDICT A SURGE IN COSMIC RAYS: Interplanetary space is about to become a more dangerous place. A new study just published in the research journal Space Weather predicts that galactic cosmic rays will surge in the decades ahead--a result of the sputtering solar cycle. This could limit deep space missions for astronauts to as little as 200 days. Get the full story at Spaceweather.com
