The 2011 Southern Brookhaven Earthquake, was a series of foreshocks, a severely strong earthquake, and a series of foreshocks that occurred on March 11, 2011 from 2:35PM (UTC) to 5:45PM (UTC), with the most powerful earthquake being a 6.5. It was the longest series of earthquakes in Southern Brookhaven, killing an unknown number of Southern Brookhavers. The earthquake illustrated to the Robloxians that earthquake shelters were effective in preventing deaths from earthquakes. A railway train derailed as a consequence of the main earthquake. After the earthquake, some buildings were rebuilt as they had been destroyed by the earthquake, and some buildings that were slightly destroyed were repaired. This earthquake caused roads to crack, causing road closures as the gaps on the roads were considerably wide. The roads were closed until April 28, 2011, when the destroyed buildings and the damaged buildings reopened.
