I felt the tremors of an earthquake today! The tremors measured 4.7 on the Richter scale with no known damage. The floor shook noticeably beneath my chair as though heavy construction was drilling up through the floor or very nearby. This is actually the second 4.6 earthquake in two weeks (first one was March 6, which I didn't notice). The stresses originated in Korumburra, which is 90 km southeast of Melbourne.
