Solar activity, as indicated by sunspots, radio noise and geomagnetic indices, plays a significant but by no means exclusive role in the triggering of earthquakes. Maximum quake frequency occurs at times of moderately high and fluctuating solar activity. Terrestrial solar flare effects which are the actual coupling mechanisms which trigger quakes appear to be either abrupt accelerations in the earth's angular velocity or surges of telluric currents in the earth's crust. The graphs presented in this paper permit probabilistic forecasting of earthquakes, and when used in conjunction with local indicators may provide a significant tool for specific earthquake prediction.

You seem to forget time, and time again that just because there are peer-reviewed research that have found that FLUCTUATING solar activity, either up or down, can trigger earthquakes it doesn't meant that they refute each other.

CO2 levels have risen as have global temperatures. You'll find many who will argue about which is the cause, which is the effect, or even if there is a relationship. While there is a correlation (both have shown an increase over the past 100 years) correlation does not imply causation.
But there is not even such correlation seen with solar (or geomagnetic) activity and earthquakes. Neither the frequency nor intensity of earthquakes follows the solar cycle.

The papers you cite to bolster your opinion are all decades old. If solar observations were such a promising way of predicting earthquakes, why has there been no progress in the past forty years?

Abstract: Various research workers have reported EM (electro-magnetic) emissions prior to the earthquakes or during earthquake sequences. In some cases these EM emissions were consistently found during certain hours of the day. These were found to be of diurnal and semidiurnal type. EM emissions of semi-diurnal type, spaced in the time domain from the local noontime, were observed in many examples prior to earthquakes/volcanic eruptions. Such emissions were also observed in a very wide frequency band from VLF (very low frequency) to Microwave range. It was also found in these examples that earthquakes/volcanic eruptions occurred simultaneously with these EM emissions. From this study, it can be concluded that the semidiurnal stresses on the earth and moon are primarily caused by the position of the Sun. This paper discusses all these examples in detail and an application for the development of reliable monitoring of precursors for earthquakes/volcanic
eruptions in high-seismicity areas.
Keywords: Telemetered network, semi-diurnal, diurnal RF emission, earthquake sequence and precursors.

The impressive development of the Earth sciences on the basis of new precise Crust condition
parameters measurements permits to estimates the probabilities for earthquakes risk. But the
prediction the time, epicentre and Magnitude of incoming earthquake is not a solved problem.
Many scientists are state that this is not solvable. Such pessimism is right because of very
scare time and space set of Crust movement parameters monitoring and the uncertainties of
our today knowledge for the Earth and its magnetic field. The local "when" Earthquake
prediction is based on the connection between geomagnetic "quakes" and the next incoming
minimum or maximum of tidal gravitational potential. The probability time window for the
predicted earthquake is +/-1 day for the minimum and +/-2 days for the maximum. The
preliminary statistic estimation on the basis of distribution of the time difference between
predicted and occurred earthquakes for the period 2002- 2003 for Sofia region and for Beijing
and Lanzhou regions are given. The solving of earthquake's prediction problem and creating
its theory need the efforts of wide interdisciplinary science group from physicists,
geophysicists, seismologists, Earth geomagnetism theory, Atmosphere and near space
physics, biologists, the application of temporary almost real time GIS for data acquisition,
visualization, archiving and analysis, the new possibilities for solving step by step the
nonlinear inverse problems for testing the adequateness of physical models and the reliability
of predictions. The monitoring should include standard geodetic data, seismic hazard map
developments, electromagnetic field monitoring under (electrical signals in VAN method and
its Thanassoulas's variant), on (electropotential distribution, geomagnetic variations) and over
(VLF and ULF, vertical electropotential distribution) Earth surface, atmosphere effects
(earthquake's clouds, electrical charge distribution), the behaviour of Earth radiation belts,
biological precursors. The statistical estimation for reliability of time, epicentre and
magnitude prediction is obligatory. The Beijing- Lanzhou regions are proposed as polygon for
testing the possibilities for creating research and short time earthquakes prediction
NETWORK. The important advantage of the proposal is that the geophysical seismic,
geomagnetic, atmosphere and near space monitoring exists and the research needs more
software than hardware for testing the approach and applying it in the practice.
If you are going to make an acusation make sure you are right, otherwise it just shows you are not willing to do proper research into the topic you are discussing, and instead you are willing to throw strawman arguments just for the sake of derailing such a topic.

2.6 Example 6: Observations from Apollo Lunar Seismic Experiment (APSE)
APSE consisted of four seismometers placed on the lunar surface during 1969-1972. Each station included three long period instruments and a vertical short period. The data was telemetered to earth and recorded until 1977. Deep moonquakes at the depth of 700-1000 km dominate the entire collection of data and show good correlation with the tidal stresses. It is seen from the record (arranged by synodic month) that the noisiest part of the record occurs close to the times of lunar sunrise and sunset, even accompanied with spikes. The three-day (solar day) offset in the time of sunrise/sunset (around 10 & 23 days from new Moon for station 12 and around 07 & 20 days from new Moon for station 16; station 12 and station 16 were commissioned during the Apollo 12 and Apollo 16 missions, respectively) reflects the 39 degree difference in the longitudes of the two stations. This indicates that the local noisy period is not simultaneous and varies with longitude. The pattern is similar to the semi-diurnal pattern seen on the earth at different longitudes. The power spectra of the moonquakes also show peaks corresponding to synodic month, which suggests occurrences of moonquakes during the noisy periods (Lammlein et al., 2005).
5.1. EM emission related to earthquakes and volcanoes
It is believed that the RF emissions come directly from the crystalline rocks of the crust. These rocks provide some sort of piezoelectric effect when subjected to stress.
EM emission related to earthquakes and volcanoes is a broadband phenomenon. This is broadly found in two versions, diurnal and semidiurnal type. Diurnal-type emissions are found to be more intense than the semidiurnal type. The timings of semidiurnal-type emissions are spaced equally on either side of the local noontime. The occurrences of earthquakes/volcanic eruptions are simultaneous with the emission times indicating that some stresses are generated during these periods. The causes of semidiurnal stresses seem to be the position of Sun. The causes of diurnal-type emission could be the planetary alignment, but more such cases need to be sought and examined to draw a precise conclusion.

My interpretation is that this is the result of gravitational forces, which is why a similar effect can be discerned on the Moon, which has no large intrinsic magnetic field. What the author most certainly did not conclude is that solar flares cause earthquakes.

Definition for strawman argument:
A straw man is a component of an argument and is an informal fallacy based on misrepresentation of an opponents position.(1) To attack a straw man is to create the illusion of having refuted a proposition by replacing it with a superficially similar yet unequivalent proposition (the straw man), and refuting it, without ever having actually refuted the original position.
An informal fallacy is an argument whose stated premises fail to support their proposed conclusion.
First you claimed that all the peer-reviewed research papers I presented are decades old, which not only is wrong but is "an informal fallacy".
Not only that, then in your last claim you are implying that my whole argument revolves around only solar flares when I have stated, and presented several peer-revewed research papers that state SOLAR ACTIVITY, not just solar flares can trigger earthquakes on Earth.
In case you didn't know SOLAR ACTIVITY, is not confined to just one factor, and I have clearly stated several times that SEVERAL factors influence not only seismic, and magmatic activity on Earth, but other natural disasters, and they are not confined only to factors caused by the Sun, which in case you didn't know I have also stated several times.
So again, you made ANOTHER strawman argument trying to imply that I was refering only to solar flares, which is wrong, simply because you really have no real argument at all.
