On May 31, 1897, Giles County, Virginia became the epicenter for a major seismic event that was felt throughout all of central Appalachia. Historically, the area near the West Virginia / Virginia border has been one of the most active seismic regions of the eastern U.S. This is because it's on the edge of the rock formations that were shoved (over hundreds of thousands of years) upward when the African Continent slammed into North America. This event is referred to as the Alleghenian Orogony. I'm not Bill Nye so you'll have to click the link to learn more. I will tell you that there is a very cool rock formation at the VA/WVA border along the Route 460 road cut, just past the big "Welcome to WVa" smokestack. You can see flat parallel rock to the west, layered in Limestone, Sandstone and Shale (with lots of mussel fossils visible) that was untouched by this event and folded/cracked/twisted rock to east where the impact of this slow upward thrust took place. Giles County is to the east as well so you can imagine what the the rock is like being on the edge of such a large happening. Add in large limestone deposits that have dissolved over eons from ground water, leaving huge caverns, and eventually something is going to fall. Geologist speculate that an earthquake thousands of year ago caused the side of Potts Mountain to collapse and dam up a mountain stream, creating Mountain Lake.
Getting back to '97, seismic measurement was determined by an event's effects on structures and humans since seismographs hadn't been invented yet. The U.S. used the "Modified Mercalli intensity Scale" (MMI) and measured intensity from the Roman Numeral I (weakest) to IX (kiss your ass goodbye). The Giles quake measured a MMI-VIII.
Here are some newspaper reports taken from Earthquake History of Virginia, 1774-1900 by M.G. Hopper and G.A. Bollinger (1970, pages 55-66):
Giles County, Va. and Pearisburg, Va: Report that "Angels Rest", a high mountain near Pearisburg, was cracked. (RD 6/l/97)
From Roanoke, Va.: Telegram from Giles County that Mountain Lake still intact. "Advices from Giles County, however, still report much uneasiness there. The courthouse at Pearisburg was badly cracked by the earthquake shock, and numerous chimneys were thrown down or badly damaged. In other parts of the county, it is said, several brick houses were seriously damaged, and some shaken down completely. Along the railroad track tons of rock fell from the overhanging cliffs. In one instance derailing a freight train, and causing a delay to traffic for five hours or more. At Pearisburg bricks rolled from the chimneys to the roof of the courthouse in such numbers and to such an extent that Judge Jackson, who was holding Circuit Court when the shock occurred, left the building, along with the lawyers and others present. For a week or more before the shock people throughout Giles County were much disturbed by subterranean noises, and all day Monday detonations like the explosion of distant artillery were heard throughout the county. As to the crack in Angels Rest Mountain reports are so conflicting that it is hard to get at the truth. For several days after the shock last Monday the water in many of the springs and branches were muddy. An attorney of this city who was in Pearisburg on Monday bears out some of the above statements, and says that for nearly fifty miles from that place he saw hardly a sound chimney standing. In his opinion, if the buildings throughout Giles had been largely of brick, the damage would have been very great, and serious loss of life would have occurred."
From Pulaski, Va.: "From what can be learned, all reports about cracks in the earth in Giles, etc., are fictitious. Your correspondent saw yesterday a lawyer from there who said there were no holes in Angels Rest Mountain or elsewhere there, that any one had seen, but people are afraid to go in the mountain to investigate. There was a great scare, as the earthquake was very severe, there having been four separate shocks on May 31st between 2 and 5 o'clock p.m." (RD 6/4/97)
From McDonald's Mill (Roanoke County): "I have been reliably informed that in Giles County, near Pearisburg (the county seat) earthquake shocks have daily occurred for some time past, and the citizens along the base of a lofty part of a mountain called Angels Rest are considerably excited." (RD 6/3/97)
Dr. Goodride Wilson, writing of the Town of Pearisburg: "While court was in session on Monday, May 31, 1897, Pearisburg experienced a moderately severe earthquake. The judge summarily adjourned court, jumped over the railing and ran out of the courtroom along with the lawyers and spectators. A number of chimneys were toppled in the town and some brick walls were cracked. The shocks were felt throughout the county and in several other counties in Southwest Virginia."
Mr. J. H. Hardy, in a letter, reports that his father-in-law, Mr. Sam D. May, was an attorney trying a case in Pearisburg at the time of the earthquake: "He told me that the quake was really severe there. Some thought Mountain Lake had caved in. I think the water did go down some but if there was a crack in the bottom it evidently filled up gradually." (Hardy, 1969)
Earthquake "especially strong at Pearisburg, where the walls of old brick houses were cracked and bricks were thrown from chimneys which had been damaged. A few earth fissures and small landslides were reported from this area, but no serious damage.... At Narrows (Va.) large rocks rolled down the mountains. The sounds were compared by veterans to those made by seige guns in action.... Minor tremors continued from time to time until June 6." (MacCarthy, 1964)
"There were fissures in the ground and small landslides in places where they were easy to start. At the Narrows ( Va.) it was claimed that a motion like the ground swell of the ocean was observed." (Eppley, 1965, p. 25).
"Earthquake shocks nightly in Giles County since the 25th; large fissures have been made." (MWR)
Noises heard from May 3 to May 31 and after. Shock most severe near Pearisburg. No serious damage, but old brick houses badly shaken and many chimneys cracked and top bricks knocked off. Much noise.

"It was a warm sunshiny day in early summer when, without warning, buildings along Main Street begun a rocking movement and the dry timbers in their frames popped and cracked and the air became full of dust. Many people ran out of the houses into the street, some whitefaced, and stared upward where the dust, shaken from the buildings was slowly settling toward the ground. The tremor lasted only a few minutes before the panic was over and normal business was resumed along the street.
