How We Really Measure Earthquakes: The Moment Magnitude Scale
In this video we discuss the destructive power of Earthquakes, how they are measured, and what impacts they can have.
00:00 Introduction
00:25 How do we measure earthquakes?
01:36 MULTIPLY! (How it really works!)
02:32 But it's all made up! How strong are they?

Moment Magnitude Explained—What Happened to the Richter Scale?
www.iris.edu/educate for more animations
Scientists have developed far-more sensitive seismometers that, with faster computers, have enabled them to record & interpret a broader spectrum of seismic signals than was possible in the 1930's, when the Richter magnitude was developed. The Richter Magnitude Scale is effective for nearby earthquakes below magnitude 7, but not for larger earthquakes. The Moment Magnitude Scale uses seismograms plus what physically occurs during an earthquake (which can also be derived from seismograms), known as the "seismic moment". The seismic moment defines how much force is needed to generate the recorded waves. That information is plugged into the moment magnitude scale to give us the amount of energy that is released during an earthquake.

Since we usually hear about earthquakes with ratings somewhere between 3 and 9, a lot of people probably think of 10 as the top of the scale and 0 as the bottom. In fact, there is no top or bottom to the scale!

Earthquake Magnitude Power Comparison
In this 5th episode, we compare the power released for the biggest earthquakes, from an everyday 2.0 earthquake, to a 5.0 objects shifting quake, we get a visualization of how powerful certain quakes are.
Each increase in magnitude is 33 times more powerful than the previous one.

How Does The Richter Scale Work?
Nepal has been hit by two huge earthquakes, a 7.8 and a 7.3 on the Richter Scale. What are the different ways seismologists measure earthquakes and what do these ratings mean?

Moment magnitude scale
The moment magnitude scale (abbreviated as MMS; denoted as MW or M) is used by seismologists to measure the size of earthquakes in terms of the energy released. The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped. The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale (ML). Even though the formulae are different, the new scale retains the familiar continuum of magnitude values defined by the older one. The MMS is now the scale used to estimate magnitudes for all modern large earthquakes by the United States Geological Survey.

3D Supermarket - 10 Earthquakes Comparison
🛑Watch my Empire State Building Simulation: https://youtu.be/YAVyGeF8jt8
Watch this 3D Supermarket being tested for 12 different sized earthquakes!
This project took me a full week of work to finish.
I hope these simulations will bring more earthquake awareness around the world and educate the general public about potential earthquake related hazards. SHARE this video on social media
to spread more awareness about
earthquake damage!
Huge thanks to @CaSeismograph for becoming sister channels! They are streaming a live seismograph from Los Angeles, California, 24/7. Make sure you check all their educational resources on their website! Important!!

How to Measure an Earthquake
Welcome to this Mometrix video lesson on measuring earthquakes! But before we talk about measuring earthquakes, let’s define them. The earth is composed of several layers, some of which are called mantles. The outermost layer is called the lithosphere, and the outermost layer of the lithosphere is the crust, which is what we stand on every day.
