How many earthquakes have occurred in the us in ten 100 years?

In the past 100 years, the United States has experienced thousands of earthquakes, with significant variations in frequency and intensity across different regions. The U.S. Geological Survey (USGS) estimates that there are about 20,000 to 30,000 earthquakes recorded each year, though most are too small to be felt. Over a century, this could amount to millions of seismic events, but only a fraction cause damage or are widely reported. The exact number can vary depending on the criteria used for counting and the monitoring capabilities.
