March 1875 Southeast tornado outbreak

The March 1875 Southeast tornado outbreak was a deadly tornado outbreak that affected portions of the Southern United States from March 19–20, 1875. At least 19 tornadoes were recorded, including seven that were destructive enough to be rated F4 by Thomas P. Grazulis. The worst damage and most of the deaths occurred in Georgia. Most of the damage appears to have been the result of two tornado families that moved along parallel paths 12 to 15 mi (19 to 24 km) apart through parts of Georgia and South Carolina. These families each consisted of numerous long-tracked, intense tornadoes. The deadliest tornado of the outbreak was an estimated F4 that killed 28–42 people in and near Sparta, Georgia, and Edgefield, South Carolina, on March 20. A separate F4 that followed a similar trajectory may have killed as many as 30. In all, this outbreak killed at least 96 people, injured at least 377, and caused at least $650,000 in losses.[1][nb 1][nb 2][nb 3]

The ratings for these tornadoes were done by tornado expert Thomas P. Grazulis and are not official ratings.

Sparta, Georgia/Edgefield, South Carolina

A large F4 tornado tore a damage path 75 miles (121 km) long ranging from 300 yards (270 m) to over 1 mile (1.6 km) wide across portions of Georgia and South Carolina. The tornado caused its first damage northwest of Sparta, Georgia, in Hancock County, after which it destroyed dozens of farms. Four people were killed in Hancock county, three of them on one farm. A door hinge from the farmhouse was found embedded 3 inches (7.6 cm) deep in a tree more than 1⁄4 mi (0.40 km) away. At least six people died in Warren County, including one at a church west of Warrentown. The pastor attributed the survival of the majority in the church to the pews, which stopped some of the falling timbers. The tornado then moved through Camak, where 39 of the town's 40 homes were damaged or destroyed. At least seven people, possibly as many as nine, were killed in McDuffie County, most of them in small cabins. The death toll in Columbia County may have been as high as 20, though only eight deaths were confirmed. At least four people died in Appling, and as many as eight may have died on a plantation. The tornado then crossed the state line into Edgefield County, South Carolina where damage was less severe. Here, six farms and plantations were destroyed with three fatalities. The tornado finally dissipated south of Edgefield. The death toll from this tornado is listed at 28, but due to uncertainties, it may have been as high as 42.[13]

Notes

  1. ^ An outbreak is generally defined as a group of at least six tornadoes (the number sometimes varies slightly according to local climatology) with no more than a six-hour gap between individual tornadoes. An outbreak sequence, prior to (after) the start of modern records in 1950, is defined as a period of no more than two (one) consecutive days without at least one significant (F2 or stronger) tornado.[2]
  2. ^ The Fujita scale was devised under the aegis of scientist T. Theodore Fujita in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.[3][4] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[5] Canada used the old scale until April 1, 2013;[6] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[7]
  3. ^ Historically, the number of tornadoes globally and in the United States was and is likely underrepresented: research by Grazulis on annual tornado activity suggests that, as of 2001, only 53% of yearly U.S. tornadoes were officially recorded. Documentation of tornadoes outside the United States was historically less exhaustive, owing to the lack of monitors in many nations and, in some cases, to internal political controls on public information.[8] Most countries only recorded tornadoes that produced severe damage or loss of life.[9] Significant low biases in U.S. tornado counts likely occurred through the early 1990s, when advanced NEXRAD was first installed and the National Weather Service began comprehensively verifying tornado occurrences.[10]
  4. ^ a b All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time and dates are split at midnight CST/CDT for consistency.
  5. ^ a b Prior to 1994, only the average widths of tornado paths were officially listed.[11]
