How is ground acceleration different from the Richter scale?
Earthquakes are one of the biggest natural disaster risks in some parts of the world. In this exercise you will add the USA Earthquake Risk layer to your map and assess the earthquake risk in several areas.
Find the USA Earthquake Risk layer by selecting “Add” then “Browse Living Atlas Layers.” Next select “Landscape” then “Ecology” and “USA Earthquake Risk.”
Add the layer to your map by clicking “Add layer to map (as layer).”
In the Content window on the left side of the screen, click on the ellipses below the layer name and then select “Show item details.” A new screen should appear in your web browser that describes the dataset in the Description and Dataset Summary sections. If more information about the dataset is desired, users can click on “Link to source metadata” toward the bottom of the page. Answer the question about the dataset.
Ground acceleration is not a measure of the total energy (magnitude, or size of) an earthquake event. It is the geographically specific effect of that event. Ground acceleration is the intensity of how hard the earth shakes sideways in a given area.
