About the data
The Quake Tracker displays quakes from the past 30 days with magnitudes above 3.0 in Northern California, 4.0 in Southern California, 5.0 in the United States, and 7.0 anywhere in the world. Quakes below magnitude 3.0 are often not felt and do not appear on this map.
Intensity contours show how strongly a quake was felt and are displayed on the Quake Tracker when available. Rather than a gauge of pure shaking, intensity takes into account the effects on people and damage to infrastructure. The measure is designated using Roman numerals.
