Christa Suchowski searches through a home destroyed by a tornado in Marysville, Indiana. Calm weather gave dazed residents of storm-wracked towns some respite on Sunday as they cleared up after the recent chain of tornadoes.

Washington - Americans in the South and Midwest were on Sunday searching for survivors and beginning to clear up the damage wrought by a series of around 100 tornadoes which killed at least 37 people.

According to CNN, 18 people were killed in Kentucky, 14 in Indiana, three in Ohio and one each in Alabama and Florida.

The tornadoes, which the National Weather Service called an “enormous outbreak” first touched ground on Friday and lashed a vast region of the central United States on Friday from Alabama to Indiana.

Some of the worst devastation was reported in the southern Indiana towns of Marysville and Henrysville, 15km apart near the Ohio River. With populations of about 2 000 each, Marysville was described as levelled, while Henrysville was severely damaged. - Sapa-dpa
