On average there are over 14,000 earthquakes with magnitude higher or equal to 4 each year. In this visualization, small yellow
) are earthquakes with magnitudes between 4 and 6, or 1-6 for Utah. Large red spheres (
) are earthquakes with a magnitude higher than 7. In between, the color and size of spheres are interpolated.
Earthquake depth is exaggerated by a factor of 6. The orange lines (
) represent the boundaries of the tectonic plates. Earthquake data from
to visualize the actual depth and the exaggerated depth. The list below displays the earthquakes with magnitude
higher than 7 in chronological order.
