How do they use seismometers to locate the origin of the earthquake?
You can think of this in the same way that satellites work to find your location for the GPS in your car. An earthquake happens and it is picked up on 3+ seismometers. These seismometers measure the waves that the earthquake produced and the velocity at which they are traveling and you look at where all the seismometer calculations run together. You have the epicenter of your earthquake.

What is the difference in earthquake measurement by the Richter scale vs the Modified Mercalli Intensity Scale?
The Richter scale measures the magnitude of an earthquake based on the energy released at the source, using a logarithmic scale. In contrast, the Modified Mercalli Intensity Scale measures the intensity of shaking and the damage caused by an earthquake at a specific location, using a descriptive scale from I to XII. The Richter scale provides a more standardized and quantitative measure of earthquake size, while the Mercalli scale gives a subjective assessment of the earthquake's effects on people and structures.
Where is an earthquake's focus located?
An earthquake's Focus is located directly under the Epicenter of an earthquake. The Epicenterof an earthquake is located on the surface of the earthquake.
