Map of California….

The following link goes to a map of California. You can click on the map and see the MMI for each area. MMI stands for “Modified Mercalli Intensity.”

Usually, we hear about “Magnitude.” Magnitude measures the energy that quake produces. It’s a number that doesn’t change, whether you live near the quake or far from it. The quake in the California’s Ridgecrest area (epicenter) in on Friday, July 5, 2019 was a magnitude of 7.1.

On the other hand, intensity (what the map in the link above shows) measures how a certain area is affected, the intensity that area feels. If you are far from the epicenter, the intensity of your area will likely be lower than the intensity of an area closer to the epicenter–because the closer area will probably be feeling the tremors more intensely.


The “Big Quake” in Japan on March 11, 2011 had a magnitude of 9.0. or 9.1–I’ve heard both numbers.

Here is a link to the intensity felt in Japan during that earthquake:

My home of Fukushima was a 5+, so that is what I felt when that quake occurred.


I’ve heard that they’ve been having a lot of aftershocks in California.

❤ Or if you are now in California, YOU have been experiencing lots of aftershocks!!!!! ❤

Those aftershocks are terrifying.

With the following link, we can see the aftershocks that California is now experiencing:

Hang in there!!
