The USGS estimates that several million earthquakes occur in the world each year.
Many go undetected because they hit remote areas or have very small magnitudes. The NEIC now locates about 50 earthquakes
each day, or about 20,000 a year.
As more and more seismographs are installed in the world, more earthquakes can be
and have been located. However, the number of large earthquakes (magnitude 6.0 and greater) has stayed relatively constant.

Starting in January 2009, the USGS National Earthquake Information Center no longer
locates earthquakes smaller than magnitude 4.5 outside the United States, unless we receive specific information that the
earthquake was felt or caused damage.
The values in the tables for the most recent years may fluctuate due to magnitude
updates during the review process.

Earthquake Information for the 1990s
Graphs of Earthquake Statistics
We detect, but generally do not locate, about 50 mine blasts (explosions) throughout
the United States on any given business day. These blasts typically occur between noon and 6 PM local time Monday through
Saturday. Of these, about one event every two days is large enough that we compute a location for the blast and post it to
a separate explosions listing.
