Walhalla is a mountain city in Oconee County, South Carolina, United States. It is located 16 miles from Clemson University in Clemson, South Carolina and is also located in the Appalachian Mountains of South Carolina. It is the county seat of Oconee County.
The town is built mostly on types of granite rock. It is also near some minor faults and therefore subject to small and infrequent earthquakes. The last nearby earthquake had its epicenter in Newry, South Carolina, and occurred at 7:42 am EDT on May 19, 1971. The earthquake had an intensity of VI in Newry as measured by the Modified Mercalli Intensity Scale. The cause of the Newry quake was likely a slippage of the Brevard Fault and other faults in the area aided by the immense weight of the man-made Lake Keowee, created by the Keowee Dam.
Due to its German heritage, Walhalla is also known for its annual Oktoberfest celebration, which begins on the third Friday of October each year. The festival takes on Main Street in Walhalla (Hwy 28) and on the city's Sertoma Field, located between the high school and downtown (Hwy 183).
