Explanation of Colors - USGS Earthquake Hazards Program
The first example shows how the colors change as the shaking at a location progresses from no shaking through weak, moderate, and strong shaking, peaking at a violent shaking level (very dark red), before the shaking dies off (red becomes brighter).

The Earth's surface is transformed by movement along active faults, producing features that help us determine the location of the fault and are diagnostic of the fault's level of activity. Examples are provided in the block diagram below.
Map of earthquake probabilities across the United States
Ground shaking is the most powerful predictor of damage from an earthquake. The U.S. Geological Survey (USGS) National Seismic Hazard Map shows the strength of ground shaking that has a 1 in 50 chance of being exceeded in a particular place in the lower 48 states over a period of 50 years.
