Some local residents may have felt the rumble of two minor earthquakes recorded in the northwestern part of Greene County on Sunday afternoon.
The two earthquakes, at 12:31 p.m. and 12:36 p.m., were magnitude 1.8 and 1.6, respectively, according to data from the U.S. Geological Survey (USGS).
The first earthquake, of magnitude 1.8, was recorded at a depth of approximately 1.8 miles, an estimated 3.1 miles northwest of Greeneville.
Five minutes later at 12:36 p.m., a second earthquake of magnitude 1.6 was recorded at a depth of approximately 6.2 miles. Its epicenter was within a mile of the first quake.
According to the website earthquaketrack.com, which compiles and creates maps of the USGS data, the two earthquakes are the only ones to be centered in Greene County during the past several years.
The last Greene County-centered earthquakes were of magnitude 3.6 and 2.5 on Aug. 25, 2005.
