Magnitudes 4.0 – 7.0

6.8 2018.JPG

In the image above, a Magnitude 6.8 is reported as occurring in 2018. An event of this size can look alarming. Is The Big One next? Since this earthquake is now nearly 2 years old, we can say no. Furthermore, others of this size should not cause distress. As such, this page is available to help alleviate any concerns regarding events of this type.

Let’s look at some recent history. Below is an Excel pivot table I generated using data from the United States Geological Survey (USGS). The table shows the number of times earthquakes have struck the region between 1/1/2010 & 7/22/2020 as of 1:00 pm. I only ran magnitude 4.0 and above! Magnitudes of 3 & below happen A LOT. FYI my last pivot table had shown “sum of magnitudes” rather than “count of magnitudes” Oops! My mistake. The below image has been corrected.

I’ve added this page because I think it’s important to know when to be worried. Yes, history shows us we are overdue, but seeing articles in the paper about these smaller quakes should not be cause for alarm. They are just business-as-usual for the region.
