for several years now... no more average higher mag quakes like we used to have. Can anyone offer an explanation???

Here's a listing binning quakes by whole magnitudes for each year, 1950 through 2019.
Data is from the USGS.
Keep in mind that as time goes on, there are more seismometers, and they get more sensitive. So naturally the number of quakes reported in the record increases, especially in the lower magnitudes.
The catalog is essentially complete for mags 6+ for this time span, except for an anomaly for mag 6 from 1973 to 1982 which I still haven't figured out.
Anyway, except for rando fluctuations and increases as aftershocks due to the largest events, there is not change in the rate of quakes.

Solar minimum is the period of least solar activity in the 11-year solar cycle of the Sun. During this time, sunspot and solar flare activity diminishes, and often does not occur for days at a time. The date of the minimum is described by a smoothed average over 12 months of sunspot activity, so identifying the date of the solar minimum usually can only happen 6 months after the minimum takes place. Solar minima is correlated with changes in climate.[citation needed]

lack of sunspots is what is causing the lack of high magnitude earthquakes.

This research inspects possible influence of solar cycles on earthquakes through of statistical analyses. We also discussed the mechanism that would drive the occurrence of increasing of earthquakes during solar maxima. The study was based on worldwide earthquakes events during approximately four hundred years (1600- 2010). The increase of earthquakes events followed the Maxima of Solar cycle, and also depends on the tectonic plate location. From 1600 until 1645 events increased during the Maxima in some of the tectonic plates as Pacific, Arabian and South America. The earthquakes analyzed during two grand solar minima, the Maunder (1645-1720) and the Dalton (1790-1820) showed a decrease in the number of earthquakes and the solar activity. It was observed during these minima a significant number of events at specific geological features. After the last minima (Dalton) the earthquakes pattern increased with solar maxima. The calculations showed that events increasing during solar maxima most in the Pacific, South America or Arabian until 1900. Since there were few records during these three centuries we needed additional analysis on modern data. We took the last four solar cycles events (1950- 2010) and made similar calculations. The results agreed with the former calculations. It might be that the mechanism for the Sun-Earth connection relies on the solar wind speed. In both records (1600-1900) and (1950-2010) the results showed a significant increase in earthquakes events in some of the tectonic plates linked to solar maxima. The Solar wind energy striking the Earth's magnetosphere affects the entire environment because the pressure on the region increases and the magnetosphere shrinks sometimes four Earth's radii. This sudden compression causes earthquakes in specific plates. During the times of solar minima the pressure from the solar wind on the earth decreases, then the magnetosphere expands and earthquakes happen in a different pattern according to the geological feature on earth's surface less frequently. Solar driven events include coronal mass ejections (CME) and coronal holes, which are at a maximum during the descending phase of solar activity. The tectonic are important because there is heterogeneity in the crust and the tectonic stress depends on each region. The geo-effectiveness of solar wind from a coronal hole only depends on the position of the hole relative to the Earth and for the CMEs an additional factor is their velocity. The influence of these solar events could be detected from electromagnetic variations on the ground prior the earthquakes. The goal in this research was to show the solar events influenced the earthquakes and seismologic events following some special display and also how the Sun's activity played to make earthquakes increase. This paper discussed details of this mechanism, calculations and associated factors.

Jordan;
This looks like another instance of correlation vs causation.
If the sun could exert enough force on the earth to cause quakes it would be sufficient to cause massive fatalities.

you're trying to dismiss this with a wave of the hand roger...there are other "forces" that could be causitive...especially if you consider that human activity affects sunspot cycles...course you have to understand that we are talking about living entities to gain any traction...

I have read it can be, but so far since I checked the archives, its about average for the last 9-10 years. thks for clarifying-had to ask, because no where did you mention the sun cycle.

Terral Blackstar tries to explain that. He is planning to take his group down a bottomless pit in Arkansas. His group makes and sells colloidal silver.

Yes, I've heard of him recently. And he's written lots of letters/reports to various geologists, and other scientists too. They don't seem to know why either. So why don't other so called experts, geologists here want to answer this?

Good question. In the link he responds to a government geologist named Lisa. He thinks she has to take the government line that nothing unusual is going on.

I don't understand your concern.
From 2010/1/1 to 2020/6/4 we have had 1544 quakes of mag 6+ globally.
