Another 6.0 Magnitude Earthquake

How Many 6.0+ Magnitude Earthquakes Happen on Average Each Year?

About 4 hours ago, a 6.0 magnitude earthquake was recorded near Sand Point, Alaska, United States. The only real worry is if it causes a tsunami. At this point, there hasn't been a warning issued.

This is the 5th 6.0+ magnitude earthquake in the last 30 days.

6.0+ magnitude earthquakes are not exactly rare, what makes them rare is where they happen. We normally get between 130-200 of these earthquakes around the world each year. The range is a bit wide because I have found several images giving different values, even if they look like the exact same information.

Two of the graphs reference the U.S. Geological Study data. Here is thier chart on the number of earthquakes from 2000-2016 for each magnitude. This data gives about 141.9 magnitude 6.0 earthquakes on average between 2000 and 2016, with 2012 being the lowest at 108 and 2011 being the highest at 185.

According to Wikipedia's earthquake list, 2017 had the fewest so far with only 107 earthquakes. But, their data only shows 2008 to 2018. If we got back to the source, we see that the USGS also shows records for 1990 through 1999. In that period set, 1991 had only 96 magnitude 6.0 earthquakes.

Right now, we have had only 42 magnitude 6.0 earthquakes for the year. So, unless we see a major uptick in the 2nd half of the year, this year might be the lowest amount of hazardous earthquakes on record.

Even the number of 7.0 magnitude earthquakes is half of what it is normally. The average is 13.7 and currently there have only been 5 this year. Last year only had 6 magnitude 7.0 earthquakes.

We are in an earthquake drought.

But, since we only have a few decades of data, we don't know if this is normal. If you read my Space Weather reports, you know that I believe that there is a correlation between the Sun's activity and earthquakes. The Sun has been less active in the last two years and things seem to be changing in how it affects the Earth.

Without more data, we can't be sure if this is a sign of something bigger coming.

Could this just be a prelude to a much larger eruptions?

Or is it a sign of an impending polar shift, like discussed in the review I wrote: How it Ends : A prepper discussion
