Late in the evening on Tuesday, March 14th, a small earthquake shook parts of east Georgia. According to Pam Tucker, the Emergency Services Director for the county which includes most of Augusta, citizens reported hearing a loud boom and feeling vibrations at around 11:20 PM.


The star on the above map shows the epicenter located by the U. S. Geological Survey (USGS) using seismographs in the surrounding region. While the Atlanta Journal-Constitution reported a 1.8 Richter magnitude, the USGS has a 2.1 magnitude. The USGS also estimates a 5 km depth for the focus, the point in the crust where the seismic energy originated. There are old thrust faults in this area, mostly inactive although they do sometimes produce minor tremors as apparently occurred Tuesday night.

Your school is apparently on an island off of Papua, New Guinea. It is wonderful that the internet is bringing together people with common interests so far apart in distance!

Saw your comment at my blog and came to check out your post. To answer your question, my husband felt it, and asked if I had heard an explosion, but I just thought it was one of the cats jumping off the fridge and knocking something to the floor.

Thanks for letting me know where the epicenter was located.

I am not sure exactly where that epicenter is myself. Would that along the shore of Russell Lake?
