Richter Scale Day
April 26 is the birthday of Charles Richter who invented the Richter Scale
For those not familiar with the Richter Scale, it compares the size of earthquakes. For those who live in earthquake areas, it is a very familiar term and after every earthquake, we all wait to see what the magnitude of the earthquake was.
Charles Richter (April 26, 1900 - September 30, 1985) spent his entire career at the California Institute of Technology (Caltech) as a seismologist. Along with Beno Gutenberg, the Richter Scale was invented in 1935. Richter gets the credit but all reports say they created it together.
Science Stuff
I can guess pretty accurately the magnitude of an earthquake that I feel because I have lots of experience. However, the designers of the Richter Scale knew their math and I don't which makes me trying to explain the formula almost impossible. Here is where you can go to find the actual formula and a lot more information on the process.
- Richter Scale Information and Formula
The original formula is: M_\mathrm{L} = \log_{10} A - \log_{10} A_\mathrm{0}(\delta) = \log_{10} [A / A_\mathrm{0}(\delta)],
I may not get the math but I do know the magnitude as it applies to me.

Supply kit that is easy to store
We collect our supplies and rotate them on a regular basis but still have a kit. It goes with us on road trips but in an emergency at home, it would certainly supplement what we already have. Even if you don't live in earthquake country, being prepared is never a waste of time or money.

What could be more fun? My ideal Saturday would be watching earthquake disaster movies with a large bowl of popcorn. - California Earthquakes
Earthquakes are a unique experience. We go about our daily business until the ground moves under our feet and we are reminded how small we really are.

The debate rages on
While I would never live in tornado alley, those who live there say they wouldn't live here with the chance of earthquakes. I find this fascinating so I am curious to see how this really turns out. We all know there are no safe areas. There are tornado's, hurricanes, and earthquakes. Even those who don't deal with those have other issues like blizzards. This is San Francisco in 1906.
Where would you prefer to live?
Emergency supplies to consider
We like this. There are a lot of things in our house that would fall and break. This is simple and easy to use.
Reading the reviews, I decided that even with the limitations they list, it would be worth the money to purchase the crank generator. We lost power when a "real" tornado actually hit our area. This is So Cal, we don't have tornadoes. It was pretty scary being unable to contact anyone, even for basic services.
Seismograph Machine
Every time there is an earthquake be it small or large, the first thing our local news shows is their Seismograph. It is so familiar that we scarcely look at it anymore but as children it was fascinating. The Griffith Park Observatory had one when I was small too and we would jump on the floor to make it move.

Real-time Seismogram Displays
USGS is my favorite website when it comes to anything earthquake. As I mentioned before, it is bookmarked for instant access. Today, the drum-type seismographs has been replaced by more modern technology, but the concept is the same.

This is part of the USGS website but a specific link to the seismograph display. - The USGS Website
This is a great site for those who want to know more about earthquakes and other geographical features.
Happy Birthday to Charles Richter - Leave a comment and wish him happy birthday too
Hi, Enjoyed reading your hub. I still find the Richter scale useful and very interesting. I already lived in tornado ally and now live in Hurricane state.
Congratulations on your Purple Star for this lens - a great and well deserved honour. Blessings.
When I saw the heading for this, I laughed. We always compared our burps to what they'd be on the Richter scale. What can I say? I grew up in a small town, nothing else to do!
Interesting read, and belated birthday wishes to a clever mathematician and seismologist. Charles Richters formula would be complete double-dutch to most of us, I guess.
What a neat, informative lens. Congratulations on your purple star, and on being included in the Best of Squidoo Silly Celebrations in April. Blessed.
Glad I read this article - hats off to Chas Richter, and to you, too! Great lens!
I learned something because I had never heard of Charles Richter - nice, informative lens! :>)
I am glad that this information is available it will help so many people to decide where they would rather live to minimize experience of natural disasters.
Happy Birthday, Charles!
I forgot to say, "Happy Birthday Charles Rickter"...and thank you from the ends of the earth!
Now how did I miss Richter Scale Day? Thank you for brining this important day to our attention and congratulations on being honored for your efforts on the Best of Squidoo - Silly Celebrations in April, how wonderful for you!
