#FollowFriday

Every Friday, @CNNLightYears will suggest interesting and exciting space and science Twitter accounts to follow.

Today, @CNNLightYears is giving a #FollowFriday to the U.S. Geological Survey (USGS), specifically the accounts that tweet about #earthquakes.

The @USGS estimates that several million earthquakes occur each year, but many of these earthquakes go undetected because they happen in remote areas or have small magnitudes. The National Earthquake Information Center (NEIC) locates about 50 earthquakes each day, or about 20,000 a year, according to the USGS website.
